Hey @Dr.Bob, seeing as this thread was started so long ago lol, do you have any undamaged beakers, (1 or 3 neck) round bottom flasks left, or perhaps even distillation setups like the one you mentioned earlier in the thread still available?

Would love to buy some (am in northeast US) if you still do

Hello, I'm selling an empty co2 tank. It's good for up to 450ml of co2 and can be used for other gasses like nitrogen or argon.
Here are some images
I'm not very sure on what a good price would be so I'm going to start off at $75. DM to purchase.
Thanks

The rods would work, but I would also need something to use as a stand. I have tried using wood in the past but it does not work very well, mostly because of how light the wood is and that it rots if you spill something on it.
Do you have any 24/40 addition funnels? If so I would like to know which sizes you have and I would be willing to buy one or two.
Thanks

I have about 30 volumetric flasks and more pipetts that I can count, so I would be happy to sell them in large quantitys for a low price! My goal is primarly to get rid of the stuff, not to make a fortune.

Thanks Dr.Bob!

I just found anbother small box of hardware, mostly clamp holders, aka bossheads, and related items.

There are a few lots of items that I would be happy to sell as a group, or a few at a time, if no one buys them all.



First is 12 working and 2 stuck (free bonus in case you can fix them) anglular Castaloy clamp holders, these run about $200 in Ebay new, I would sell the lot of 12 for $60, they run from like new to well used or corroded, but all working, except for the extra 2 stuck ones. https://www.ebay.com/itm/364592963348

Next I have a set of the simpler Fisher Cataloy Flexframe Hook connectors, which are designed to simply hold 2 1/2" rods tight, can be used for lattice frames or holding clamps, but not as nice as the above ones. There are 17 of these, they run about $5 each on Ebay, I will do all 17 for $50, under $4 each, for the entire set. (I likely have more of these mixed in other lots of hardware if you want more.) https://www.ebay.com/itm/353813567122



Then I have the round Kimble type 1/2 inch lattice connectors, which are little aluminum balls with allen keys to tightten them, can be installed or taken off while lattice is intact, so very handy, but not really useful for clamps. I have 20 of these for $100, they sell for $20 new, and about $5-8 ea used on Ebay.
https://www.dwk.com/na/kimble-12-lattice-connector

Next are 8 working and 5 non-working Ohaus round lattice connectors. They are very sturdy, but harder to assemble and take off. I would ask $50 for the entire lot. https://www.grainger.com/product/404R21



And lastly I have some mixed, but similar clamp holders, unbranded, that look like the link below, and are very sturdy clamp holders. I have 12 working ones. They sell new for a lot, about $25, but I want to go with $5 each, so $60 for the lot of 12.
https://www.arborsci.com/products/90-degree-clamp

Lastly, I just found about 6 more large Fisher 3 prong Cataloy clamps, which sell new for almost $100, I will sell them for $15, as they are are all in almost new condition. There are a few VWR ones that are of similar quality as well.

I have many other clamps, rings, and clamp holders also, but these I have a bunch of similar items for people that want a set of matching ones. I also have more broken ones, if anyone wants to try to fix some for cheap.



[Edited on 11-12-2023 by Dr.Bob]

Some non-equilibrated addition funnels below. I have 2 x 125 ml ones that are PTFE stopcock. The top is a TS 222 stopper, I can provide one, this is not 24/40 compatible. There is also a graduated 125 ml one, with a 24/40 compatible top. I would ask $30 for any of them.

Also some 24/40 to 14/20 bump bulbs that I photographed for someone else, but figured I would post here before they go to Ebay. $20-25 each.

Also some Kugelrohr bulbs in many sizes and styles, all 14/20, from 5 or 10 ml up to 250, even some long ones for large amounts. They can also be used as Rotovap bump traps, or distillation bump bulbs or small solvent resevoirs for little columns, if you really reach for uses.






[Edited on 13-1-2024 by Dr.Bob]

Here are some photos of a bunch of 29/42 pieces that I have left and was photographing for someone, so I will post them for anyone what is interested in 29/42 glassware. There are many adapters, short paths (with 10/30 therm joints), vacuum adapters, gas inlets, Dean starks, addition funnels, and much more. I have more addition funnels somewhere, up to 2L size. If you should be interested in any of it, please let me know which items and either an offer or I can give you a price. Most things would be the same price as the 24/40 equivalent item.

I also have a number of 3 and 4 necked rbfs in 29/42 with straight and vertical necks of 250 and 500 ml size. i'd ask the same price as the equivalent 24/40 3 neck flaskand . I also have enough stuff to make one more "kit" with a claisen, dist head, condenser, gas inlets, and more.

Here are a couple of condensers I have, might sell one shortly, but I have several of the lower ones, which is a West condenser combined with a curved vacuum adapter, all 24/40 joints, asking $25 for it. The top one is a simple West with a 24/40 bottom joint but a simple joint at the top, like for a rubber stopper, I would only ask $10 for it.

A few more things to post I just found. Not sure what some are, but I will describe. make me an offer if you want to make one.

From the right side: 2 long fritted gas inlets - 24/40 joint on top - 2 gas barbs, tube is about 12" long. - Asking $15

Next two (and the 2 pieces on the far left are what's left of another) are 24/40 joint with upper inlet and top open tube, and a very long (~15") open ended tube going into the flask. No idea what this is for. Asking $15 each plus a free broken one to the first buyer.

Next a Snyder column with the middle floating ball broken. no idea if it will work, nexrly impossible to repair, happy to give to someone who buys anything else and pay shipping.

Lastly, some sort of bubbler thing with 2 24/40 joints anda fritted tube inside. $10 or make me an offer.

Here is another set of photos of the 19-22 kit I have slowly assembled from bits and pieces. It is nearly a full setup, with a variety of flasks (some all 19/22, some mixed with 14/20 or 24/40 joints), a few distilation heads, a claisen, 4 various condensers (one is a coil and outer jacket combo), a few odd Soxlets that may work with some of the condensers, gas inlets, and many other pieces and various adapters. Plus some adapters to other sizes, septa keck clips, and some stoppers. The one complex distillation head alone would sell for $400 new, but I am asking $150 for the entire collection. Or make me an offer. This is basically every 19/22 item I have found in the last few years all combined into one lot.

I just found a few boxes of bottles, some narrow mouth 1L amber ones, some wide mouth clear bottles, and some medium mouth amber bottles. I'm happy to sell them for $2 each, less in bulk, and would be happy to sell a box full for a good price. I also still have 100 ml clear, amber and plastic coated narrow mouth bottles, and many others. Please let me sell you a bunch and find them a nice home.

Found some cases of brand new chemicals, here are a few. The celite is a huge bottle, 1 Kg, the sodium carbonate and sodium potassium tartrate (Rochelle's Salt) are each 500 g. I would ask $20 each plus the shipping, easiest to combine a few things glass and chemicals into one package if possible.

Also, here are some of the Parr bottles, 500 ml, for hydrogenation apparatus, which was asked about recently.

[Edited on 10-7-2024 by Dr.Bob]

Here is a photo of a few of the media bottles I have available.

Someone asked me about UV lamps, so I gathered them all up and took some photos. I have tested them all, and they all work. The one wavelength 345 nm (UVL-21) ones I would ask $40 for, the single wavelength 254 (UVG-11) I would ask $50 for, and the duel wavelength (UVGl-25) I would ask $60 for.

Here is a photo of one of the 5L 24/40 rbfs I have (this one has a minor etch around the middle from a PTFE paddle, I suspect), plus a 2L and 4L sep funnel that I have cleaned up. i can provide a PTFE or glass stopper for either one. These are some of the last large sep funnels I will likely have. Asking $50 for the 5L rbf, $50 for the 2L sep funnel, and $65 for the 4L, plus the actual shipping costs. The 2L sep funnel has a straight cut drip tip, the 4L has a small chip on the tip, but in very good condition.

I have several Foxy 200 type fraction collectors available from the lab I am cleaning out. I am happy to basically give them away if you are willing to pay for shipping and handling (my cost of packaging materials) to your address. They weigh about 30 pounds, so not cheap, but likely $100 will get you one. I think most of them work, and I will ship the best ones first, so the sooner you claim one, the more likely it is to be working and cleaner. I have lots of racks as well, I'll send 2 or more with each, whatever fits into the package easily, they will each add a pound or so to the shipping. I just need to find them a home and get them out of the lab. I attached some generic photos as I have a few of them, but no photos yet.

I still have a large oven, a ductless hood for weighing and handling solids (filters the air and recirculates it), and a small benchtop hood to find homes for in the next few weeks. I also have a large stainless enclosure that is about 4 x 4 x 6 feet.

I also have an entire mid-sized hood left to remove (got 2 out already) if anyone wants to find a way to get it. I can't find a photo of it now.

Got another load of stuff processed and cleaned. The biggest thing is an automated Polarimeter. Someone had been interested in it before, but went with a manual one, so I still have the fancy one, an Azzoto® AUTOMATIC POLARIMETER +/-45 model. This used to sell new for ~$4000-5000 and sells used on Ebay for about $1500-2000. The newer model they sell now is over $10,000. I will be listing it for $1500, but if anyone is interested, let me know, it would save a lot of fees to sell it directly.

I also have a whole box of erlenmeyer flasks, mostly 1L Pyrex ones (asking $10), about 6 or so, but many other sizes as well, including one 5000 ml 29/42 stopper top flask (make me an offer). Plus I have a variety of TS 22 stopper top 125 ml erlenmeyers (5$ w/glass stopper). I am trying to catch up on all of the u2us and emails, but I have gotten very busy again, so I apoligze for the delays.

I have one or two Buchi Rotovap R114s frame and motors available from this lab cleanout. The motors works, and I have the glassware and parts to build a rotovap up from them. I do have some various water baths also, trying to test them currently. I also have all of the glassware for these, both water and dry ice condensers available. I would ask $120 for the base, the other parts would depend on which versions you want. This will likely be my last rotovap motors to sell. But I have lots of parts and pieces left.



[Edited on 13-10-2024 by Dr.Bob]

Another person asked me about pressure tubes. I have a large assortment of them, mostly from Ace, a few from ChemGlass. The larger ones use a large PTFE cap, I have a few but not enough for every bottle, so I would prefer to sell them in pairs of bottles with one cap. The smaller tubes are similar, there are two types of caps, the top sealing ones and the ones with a smaller inner O-ring, both work with any tube, but again I have fewer caps than tubes, so I would like to go 2 or 3 to one there. I would ask $20 per tube for smaller ones, $30 for larger ones, 40 for the small bottles, and $50 for the large bottles. Then $20 for the smaller caps, and $30 for the larger ones for the bottles. If you wanted more tubes or buy other things at the same time, I can provide discounts, same for acedemic buyers.

I have sold some of the flasks previously listed, but have another box of them to list. Most have larger joints than 24/40. I show an asking price, if you want more than a few I can go lower with a volume discount. Or make me an offer, I am trying to sell these to make space as I have a lot of glass right now. I do have lots of 29/42 accesories, condensers, adapters, and much more.

N - 2L Chemglass - 4 neck all 29/42 - in great condition - $35
O - 2L Chemglass - 1 neck 45/50 - in great condition - $20
P - 2L At-Mar - 4 neck - 45/50 center 29/42 x 3 sides - in great condition - $35
Q - 2L Ace - 45/50 center 24/40 x 2 sides - in good condition - $30
R - 3L unmarked, might be custom or label just work off - two 24/40 necks - in fair condition - $35 - has a very small chip on one neck.
S - 2 of these - 500 ml 29/42 one necks - one is Chemglass, other is unmarked - $10 ea
T - 1L 24/40 long neck rbf - Pyrex brand, like new - has about 3-4 inch longer than normal neck
U - 1L Chemglass - 4 neck all 29/42 - in dirty condition bu otherwise good. - $20
V - 2L Ace - 29/42 3 neck in good condition - $30
W - 2L Chemglass - 29/42 1 neck - in good condition - $20
X - 2L Chemglass - 29/42 1 neck - in good condition - $20
Y - 2L Chemglass - 29/42 3 neck - with 24/40 adapter stuck in middle joint - in fair condition - $30
Z- 2L unmarked - 29/42 3 neck - in fair condition - $30

I also have lots of 5 and 10% Pd on carbon, wet, hard to ship large amounts, but smaller amounts should be doable in the US. Also Palladium hydroxide on Carbon, which is reduced to Pd black in situ.

~10 g of Rhodium on carbon, wet, Degussa type G10 NB/W Rhodium 5%. - $ 150.00
Ruthenium (III) chloride hydrate – 5g - $100
a few small vials of 500 mg of trans-benzyl(chloro)bis(triphenylphosphine) palladium (II) - $5 ea




[Edited on 7-12-2024 by Dr.Bob]

Next 4 large flasks. I can provide more photos of any of them if you given me an email address.

Here's the last batch.

Someone asked me about the aldehydes that I have left, someone just took about half, and now have about 50 left. i just took photos of what is left, if you are interested in any, let me know and I will see how I can ship it. I have a few more basic ones as well, in larger bottles, that I would have to ship an aliquot of, to make shipping possible. That would include benzaldehyde and a few other simple ones.

Update on the round bottom flasks. Here is what is left now:

I have sold some of the flasks previously listed, but have another box of them to list. Most have larger joints than 24/40. I show an asking price, if you want more than a few I can go lower with a volume discount. Or make me an offer, I am trying to sell these to make space as I have a lot of glass right now. I do have lots of 29/42 accesories, condensers, adapters, and much more.

Q - 2L Ace - 45/50 center 24/40 x 2 sides - in good condition - $30
R - 3L unmarked, might be custom or label just work off - two 24/40 necks - in fair condition - $35 - has a very small chip on one neck.
T - 1L 24/40 long neck rbf - Pyrex brand, like new - has about 3-4 inch longer than normal neck
V - 2L Ace - 29/42 3 neck in good condition - $30
Z- 2L unmarked - 29/42 3 neck - in fair condition - $30

Plus I have more items in the photographs below:

A - ChemGlass 12L 3 neck flask - 1 center neck 55/50 - 2 side 45/50 necks - used but good condition, slightly dirty. Asking $150 here, will be $200 on Ebay shortly - SOLD NOW

These sell for $400-800, this one is new and unused - asking $150 for now, will list on Ebay for $200, I think I have at least one more similar one of these around. - SOLD NOW



[Edited on 11-1-2025 by Dr.Bob]

Not sure why the photos are on their side above, but you can figure it out, I hope. If anyone ants better photos, I can email them, just u2u me with your email (I can't send photos in the u2u system...). Here is E to H:

And lastly I and J:

I just photographed the remaining 24/40 jointed flasks, I have 2 Morton type rbfs, 1000 and 500ml, 2 250 ml 3 necks, one straight/one angled, a 1L 3 neck, a 500 ml 3 neck with an extra 10/30 therm port, and some other smaller rbfs.

I also found another box of columns, these are just a sample, but I have them from 1/2" to 2 or 3" diam, with and w/o reservoir, w and w/o frit, and w/ or w/o stopcock. I am happy to make deals on multiple columns, typically $10 each, more for larger ones, but I can do a set of different sizes for $60 with lots of extras, including silica gel, flow regulators, extra reservoirs, and you can think of more, I am sure.

I also have yet more various bottles, jars, vials, tubes, and more, hard to list it all.

Quote: Originally posted by Dr.Bob

I have a few things in that list. I took photos a while back but have not yet posted them, as they are mostly in storage right now, but I can dig them out given a little time. I have one 2000 ml 24/40 3 neck rbf with a bottom drain. - I have not set a price but it is quite a nice flask, looks like new I might have had one in 1000 ml but cannot find a photo of it so far. And I have a small variety of jacketed fixed kettle reactors, mostly from 250 ml to 1000 ml, maybe one at 2000 ml, but not sure off hand on a 2000 ml one. I do have one big one, 5 or 6 L, but it will be pretty pricey, I still need to research that one and will likely list it on Ebay, they sell new for $5-6000, and this one is pristine. I had some 10/18 glassware, a micro set which I sold, but I might have a few pieces left, so I will look to see what is left. [Edited on 17-12-2018 by Dr.Bob]

I do still have most of the reactors show in the previous listing:

http://www.sciencemadness.org/talk/viewthread.php?tid=15667&...

I also just found a 2L reactor while looking around, it is shown below.

For the 250 ml reactors, I would ask $75, for the 500 ml ones - $90, for the 1L ones, I'd ask $125, and the 2L one below, I'd ask $200. Those are about 2/3 of the lowest Ebay prices I see, which are just for the bottom piece in most cases.

I will have to try to find a matching top, I only have a few of those to choose from. What I DON'T have are the needed O-rings and seals to connect the two pieces. I don't know where they went, but I don't have them, you will need to find them. But they are available. If anyone knows a good source, please let me know. As I get more time, I will try to make sets with those parts, but I have not had time to do that yet.

I don't know if burning benzene will work in these, but it likely won't hurt it. I might even have a porcelin dish that would fit in it.



[Edited on 22-1-2025 by Dr.Bob]

I also just took new photos of my remaining condensers. I got some for some trades, some I just dug out, and others I have had. I also have a few Wests I have in some 24/40 kits that I am putting together.

I have a bunch of Allihans for $20 each for the unlabelled ones, $25 for the LG longer one. The Fredrichs both have issues, one is new but the inner tube is broken, easy enough to fix, the other one is missing the inner tube and adapter, they would be $20 each. The Vigreauxs are $20 each, and I have two small liebigs for $20 each. The coil condenser are $25 for the Chemglass coils, and the like new Synthware reflux coil one.

I also has someone ask me about stirrers, I have three working ones. I don't have any heating stirplates right now, but trying to get some fixed. The Corning PC-410 is the newest, the dial is damaged, but otherwise it is great, I would ask $60. The Corning PC-310 is older, $50, and the VWR 310 is $50.

Here are two boxes of books I would like to give away for postage only. First come, first serve, but I will be out town soon for a little while, so I may have to arrange shipping then, but books will be allocated basedd on the first to u2u or email me. Cost would be ~$5 for one or two books, ~$10 for a medium sized box, and about $15-20 for a large box, as media mail rate is low for large boxes.

These have been claimed so far:
CRC Handbook
Protective groups in organic synthesis
The excitement and fascination of science
Effective writing for Engineers, Managers, Scientists


[Edited on 3-2-2025 by Dr.Bob]

@Dr.Bob, looking at the condensers in this reply:

1. Are either of the condensers still in stock?
   
2. Do either of the condensers include the feedstock valve like what you posted here?
   
3. On both of those condensers I see a red fastner nut thing, do you know what that's for? Im wondering if it could be used for a temperature probe for an R-205 rotovap.
   

Here is another list of books to give away, I have a few people that asked before but were too late, they get first dibs on these, but any other requests will be first come first serve.

Superoxide,

I don't have any water condenders like shown above, but I do have several of the simpler ones like shown below. They can also be set to allow adding more material while in use. The red nut is a cap that seals the vacuum inlet, but can be replaced by an inlet adapter or other 5mm tube. The first two has threaded hose adapters, the second two have standard hose barbs for the water and vaccuum lines. I can provide the stopcocks, threaded connector and other parts as well. These are listed on Ebay for up to $200, but I would sell them here for about $150, plus shipping, depending on what other parts you need.




[Edited on 26-2-2025 by Dr.Bob]

Here are a few more flasks I just unpacked. These are mostly 24/40 joints.

A - 24/40 2L evaporating flask - Chemglass - $30
B - 24/40 2L RBF with 1 neck - Pyrex - $25
C - 24/40 1L RBF with 3 necks - Pyrex - $25
D - 29/42 evaporating flask - ? - $20
E - 24/40 1L RBF with 1 neck - Prism (local Co) - $15
F - 24/40 1L RBF with 1 neck - Chemglass - $15
G - 24/40 2L RBF with 1 neck - Kontes - $25 (lost photo, working on it.)





[Edited on 2-3-2025 by Dr.Bob]

I have yet a few more big things to sell. First off is a large rotovap, which I do not know much about. It likely worked, but I don't know for sure, and don't have the space or time to test it. The good news is that means I just want to sell it for parts or repair, and you can have it for a fraction of its original cost. Shipping would likely be more than the cost, so if you are near NC it would be easier to arrange a low cost way to pick up or deleivery it. But I can try to arrange shipping as well, for enough money. Make me an offer or let me know if you are interested.

Next up is a chiller/heater circulator system. From USA Lab, a UHC-50/40 system that sells new for $10K. It is fairly new and was working recently. It was used with a large jacketed reactor. This we are looking for an offer of $3000 to $3500, plus shipping or pickup. Also available, a huge vacuum/pressure pump from GAST, a 4565-V150, a 6HP motor, runs on 208V 3 phase. A big momma. And last I have a portable clean room, 8 x 8 x 8 feet, with Hepa filters, fans, lights, and more.

I misposted this originally but here are some photos of my remaining 14/20 short path condensers. I am asking $50 for most but would do $40 for the top left one.

Here are some more heating mantles I just unpacked. They are for 150, 250, 500, and 1000 ml rbfs, all are Glas-Col, cords are included. The prices would be the ones in the spreadsheet, except for that second 1000 ml one is very beat, so it would be 1/2 off of the listed price for used.

Also just found a Coors 60245 Buchner funnel which is listed as 125 mm filter paper (this one seems tight for that, but works OK.) They have a 600-700 ml working volume above the filter plate. Made of Porcelain. This particular unnel seems to have a rough interior due to what looks like a medocre glazing job by Coors. Otherwise it looks almost new, barely ever used. Someone asked for me one of these a while back, if they contact me, I will give them first dibs, but otherwise it can be yours for $40, plus I have a partial box of 125 mm Whatman filter paper I will include with it. Shipping might be $10 or more as it weighs over 2 pounds.

I found a few more working stir and hot plates, have a bunch I am trying to get fixed as well. The first is a simple Cole-Parmer stirring only plate. It works smoothly at various speeds, great for use with a heating mantle or for RT reactions. I would ask $45 for it, plus shipping, likely about $10-15.

Next is an old Corning PC-351, which dates back to when I was in college, but also works well and is very reliable. But due to its age and condition, I would only ask $75 for it, plus shipping, likely about $12-20 (east to west coast).

Lastly, I have a nearly new 2L heating mantle that I just found (asking $60 as it is so nice), it appears to be barely used, and I have a matching 2L 24/40 rbf available for another $20, if you buy both I will go $75 for the pair, again, about $15-24 for shipping both, a little less for either one. (Please ignore the 1L heating mantle under the cord, it is already sold.)

500 ml Sep funnel sale. I have found another box of sep funnels, and will post some group photos of them. I have individual ones as well, but can't post them all here practically. So they will be in two groups of 4 each. The prices would be: (All are 500 ml capacity, all have #27 stopper except G, which is 24/40.) If anyone wants multiple items, I can offer more discounts. If you want detailed photos of one or two to consider, please let me know.

A. Chemglass with intact - glass stocpcock - #27 glass stopper - $35
B. Kimex with intact, replaceable, tip - PTFE stocpcock - #27 glass stopper - $35
C. Kimex with slightly chipped tip - PTFE stocpcock - #27 glass stopper - $30
D. Lab Glass or Atmar? with broken tip over 1" - PTFE stocpcock - #27 glass stopper - $25
E. Chemglass with broken tip about 1" - PTFE stocpcock - #27 glass stopper - $25
F. Chemglass with broken tip about 1/2" - PTFE stocpcock - #27 glass stopper - $20
G. Not sure with intact tip over 1" - PTFE stocpcock - w/ 24/40 stoppper - $35
H. Pyrex with intact tip - PTFE stocpcock - #27 glass stopper - $ 35

Just unpacked some more frits. I have 3 similar 150 ml 29/42 jointed glass frits, plus an entire box of mostly smaller frits, a few have 14/20 or 24/40 joints, but most are just straight outlet tubes, which are way cheaper and less fragile, which work well with standard filter flasks, which I also have many of. I have pretty much any size from 1ml to 60 ml in course, medium and fine, plus a few 150 ml frits, only one or two have 24/40 joints.

The prices would be the ones in the spreadsheet, less if they are dirty or the outlet tube is chipped. If you are interested in more than a few frits I can offer good discounts, or I can offer really good deals if you are willing to take an assortment, including some dirty ones, if you are able to clean them.

Been having a hard time getting on here, but here are a few more stir/hotplates for sale. I can provide more photos and details if you send me an email to email them to. B and D are being checked still, they might need some work to stir smoothly. Feel free to make offers. I posted a few stir plates a few posts back.

A. PC-320 Stirring hotplate – Corning – 575 watts - Well used, but working. Stirring is smooth and heating appears to work sell. High power for heating. Ebay price is $125 to $150, I will take $120 here plus shipping, which will be about $12-20.

C. PC-353 – Corning – Stirring only, an older unit, but still working well. 25 watts Cord is worn and frayed a little. Stirs perfectly from slow to fast with smooth stirring at all speeds. Asking $25 for this as it is old, but works well.

E. IKA analog heating stir plate – model RET S1 basic - has slow ramping stirring to avoid wild stirbars. 630 watts. Missing one foot, so will need shimming to sit level or replacement foot. The stirring does not seem to ever get to full speed, might be limited in overall stirring speed. Asking $125

F. IKA digital heating stir plate – RET CV 81 – 620 watts – Has digital speed and heating controls, slow stirring ramp up to full speed. Dials have a very slow adjustment, so need multiple turns to get to full speed or heat. Ebay price is $125 to 150, so asking $125
