I also recently put together a 29/42 distillation kit for someone, and while doing that was able to put together a second one while I was doing it.

I attached photos of the basic type kit, it would have a 100, 250, 500, and 1000 ml rb flask (either 1 or 3 necks on each), plus your choice of either a combination distillation head/claisen, or a separate distillation head (from the 2 shown, and a claisen adapter (simple or complex), gas inlet or 2, stopper, a few 29/42 septa, a Dean Stark Trap, and a choice of reflux or jacketed type condenser. I try to add any other items I can think of as well. That would be $100, plus you can add an addition funnel for $25, as well as other items you might want. I have lots of other addapters and pieces in 29/42 as well. I also have a simple distillation head in a3 29/42 joints, but it has a small crack in one joint. I can throw that in free if you want it.

Got my 4 litre PYREX Erlenmeyer today. Can fire up my EToH production1 again! Thanks Dr. Bob.

If I ever get down that way, I expect to sample of that science grade EtOH... Or at least go get a beer.

Glad it made it intact, had mixed luck with FedUPs lately, but always nice to hear a package made it in one piece.

I have been looking for some things, and found an entire box of addition funnels that just needed stopcocks that I sat aside a while back. I have managed to play the dating game with them and a box of stopcocks, and now have a bunch more working addition funnels in many sizes. from 125 to 500 ml. Some are PTFE stopcosks (first box), some are glass or PTFE coated glass stopcoks (second box), and then I have 2 more 500 ml ones, one is a needle valve type stopcock, the other is a PTFE one. I would ask the normal prices in the spreadsheet, with $10 off for the all glass ones. If you want more photos on any one, email me, please.

I also was looking for thermometer adapters and someone asked for a photo, so here is one of just some of the ones I have, not including a whole pile of 29/42 ones in a box of that stuff. i would ask $15 for the PTFE ones and $20 for the glass ones, as I am running out of the top black threaded part for them. I have some for 3 mm thermocouples, and more for 5 mm thermometers. i also have many more odd ones, some have two ports, some are larger bore inlets (10 mm and larger are common), and lots more odd things.

I also have a simple stirplate for $60, a Corning PC-310, iin very good condition and a fairly used PC-351, stiring hotplate for $80, which looks old and used, but works. These are among my last ones to find and/or get working. Shipping extra. I have a few more left, but not much, and still trying to find and test/fix them.

I have been lookinf for various things for people and found some boxes of glassware that Ihave not yet listed well or photographed, so I will be posting photos of many items per picture, if you are interested in any, please let me know which batch photo, and what items and either make me an offer or ask me for a price. Most simple items will be $5-10, more complex $10-20, including many adpaters and simple condensers, and more complex things will be higher, but feel lree to make an offer if you want. This is almost all 24/40 joints.

This is batch A and B of the pile, mostly adapters of all types:

Here is a 24/40 kit that I made for someone a while back, and they never bought it, so it is up for grabs. BTW if you were the person who asked, please let me know, sometimes emails get lost, stuff in span or I just forget. So if you asked for it, please let me know. I would ask $100 plus postage as is, I can try to swap or add things to customize it, as well as add more items for more money. You can pick any one of the three dist heads on the right side of the photo, I have a choice of all 24/40 or one 10/30 therm joint.

Then I have 2 views of most of the remaining 24/40 flasks that I have left, batch C. They would be prices as per my spreadsheet prices or again, make an offer.

Next are three batches of condensers, reflux columns, and related 24/40 items and adapters. Most condensers are $20-25, everything else is make an offer or ask for a price. BTW, all items subject to prior sale, so they may sell at any time, first come, first serve in most cases.

Next is a box of various still heads, dist heads, adapters, fittings, inlets, outlets, and many things I am not sure what they are:

A few photos I missed yesterday, 2 short paths some pig type fraction collectors and other stuff. Also one of 4 solid addition funnels, 3 are similar ones for 125 ml, and then a huge one for 500 ml in the same design. I can post photos of the others if needed. The 125 ml shown is the worst of them, the graduations are worn mostly off, but there.

Here is another pile of books that I would like to give away, prefereably a medium sized box at a time to keep the shipping easy. If you would like a pile of books, I would just ask that you pay the postage, which would be media mail, and likely $10-15 for a medium sized box of books (they are heavy ones). For math geeks, I have a copy of Wolfram's "A New Math" which is perfect for computer/math geeks (like myself), for new organic chemists, a copy of Vogel's books, and then a whole bunch more. Local people are welcome to arrange pickup for free. Happy New Year.

I have an updated spreadsheet of the basic glassware inventory. There is still some basic glasware, like beakers, erlenmeyers, volumetrics, grad cylinders, and more. Then lots of 14/20 glassware, then some 24/40 items, and still much 29/42 glassware as well.

I am selling in Europe a >150,000ml Glass Reactor in used but fairly good condition from a German manufacturer. I'm only doing simple chemistry at a rather small scale so I'm not using it. I think I'd let it go for 1400€ since I'm not putting
it in use myself but I have no idea what it's worth so please inform me if you know better than I do.

Comes with its Metal Stand (the equivalent of a cork stand but in Metal and very solid). It has a lower ball joint which is very handy whether for cleaning / draining / or mechanical stirring from underneath (like overhead stirring but from the bottom). It also comes with a big glass lid with a single central ball joint, with two metal rings and numerous stainless screws used to tightly connect / seal this or any other lid on top and with a large joint (PTFE I think) for the upper mouth. The upper mouth is fairly large which is practical (you could get a thin person in and out from it). I think it's possible to get additional custom manufactured lids, whether in stainless steel or glass, for different / more conformations.

The reactor is very solid with the glass being 0.5-10mm thick. It certainly also can make for an amazing aquarium.

If someone is seriously interested I may at some point take the time to make a photo of it.

I may be able to deliver it myself depending on where the buyer lives and what I'm up to. I'd be happy to know it's being used somewhere.

Here are some more photos I have taken for people lately of a few more things I have left.

I have 4 plastic coated 1L media bottles left, a Scott/Duran one, a Pyrex one, and two with very thick plastic coatings from Weaton. Ideal for acids or solvents that you don't want to spill if you break the bottle. They all come with PTFE lined white plastic caps. They are $4 each, plus shipping, which is about 1 1/2 pounds each, so 2 or 3 might be a good deal for a flat rate shipping box.

I also put together some assortments of magnetic stir bars for a few people, and made up some extras, $10 for 10 mixed stirbars. They each have 10, mostly small, stirbars, but most have at least one or two odd ones, and lots of fleas, a small oval, and some 1-3" straight ones. Just tell me which one you want if you prefer a specific one. First come, first gets.
