Hard to find, high quality reagents and glassware for sale!

Texium - 18-2-2024 at 20:17

I have unpacked and sorted all of my chemicals! This thread will be updated every week or two until I have finished taking inventory.

To start this off, I have some high purity salts manufactured by Merck that are still unopened in their original packaging. Prices are in USD. I am willing to ship these worldwide:
Potassium bromide (500 g) (2 available) $50
Potassium iodide (500 g) (2 available) $80
Cesium chloride (1 kg) (1 available) $250
Cesium bromide (250 g) (2 available) $100
Cesium iodide (1 kg) (2 available) $250
Cesium iodide (250 g) (3 available) $100
Rubidium chloride (100 g) (2 available) $200

Below is a spreadsheet with many other reagents that I'm willing to sell in variable quantities. It now contains an updated list of inorganic chemicals and all of the bulk organic chemicals.

I tried to set reasonable prices based on other suppliers I could find, but I didn't spend incredibly long researching, so if you find a legit supplier with a better price, I will do my best to price-match. I am comfortable shipping many things worldwide, but international orders for less than $50 may not be worth the cost of shipping. I'm also not willing to ship particularly toxic water-soluble salts or oxidizers overseas. This is clarified for each item in the spreadsheet.

Finally, I have made another spreadsheet with more niche organic compounds that I have in smaller quantities (<250 g, some as low as 1 g). I didn't want to take the time to price these since most of them are very specific. The quantities listed are the original bottle size. The actual contents may be less, but I will measure them to confirm the precise weight on inquiry. Some of them I may want to keep a few grams of as well, so the quantity that I'm willing to sell may be lower. If you're interested in any of these, just send me an inquiry by U2U and we can discuss quantity and price.

Unless otherwise specified, everything is of high quality American or European make and is in good to like new condition. I know it pales in comparison to what Dr. Bob has to offer, but I do have a good selection of 24/40 distillation glassware, which I understand he is running low on.

More niche/specialty items will be posted below, with pictures.

Have you been able to inventory more of your chemicals?

Texium - 7-3-2024 at 16:05

I've been very busy the last few weeks, but I'm going to get to it this weekend. I'm aiming to have the rest of the chemicals inventoried and posted here by Saturday night my time. The only inorganics I have left to inventory are some miscellaneous potassium and sodium salts.

Then there's a ton of organics. There's a limited number of generally useful organics that I have in large enough quantity to sell in bulk like the inorganic salts. Off the top of my head: citric acid, phenol, benzophenone, n-butyl chloride, benzyl acetate, phthalic anhydride, phthalimide, oxalic acid. I also have dozens of niche compounds in small quantities, some of which I'll likely never have a use for myself. I'll post those as a separate list. Since many of them might have limited appeal, I won't take the time to price all of them. You can just make an offer if you're interested.

Just found unopened bags of aluminum sulfate and sodium sulfate decahydrate from Dharma Trading that are too cheap to be worth splitting up:
Aluminum sulfate (5 lb) (1 available) $10
Sodium sulfate decahydrate (5 lb) (1 available) $5

[Edited on 4-21-2024 by Texium]

Texium - 9-3-2024 at 18:31

There really weren't a lot of inorganics left that were actually worth selling. This is all I added to that list:
Potassium periodate
Potassium iodate
Sodium sulfate, anhydrous
Sodium dithionite/hydrosulfite
Sodium metaperiodate
Sodium pyrophosphate, decahydrate
Sodium bromate
Sodium fluoride
Sodium formate
Disodium EDTA dihydrate
Sodium nitrite

See the updated spreadsheet for amounts and pricing (in the first post of this thread). It is also updated with the bulk organics. Niche organics will be posted in a second spreadsheet tomorrow.

The only stuff that I haven't listed is liquids. I'm not sure if it's worth the risk and hassle to ship liquids. Feel free to inquire though if you are able to pick up locally.

Texium - 10-3-2024 at 13:52

The niche organic compounds spreadsheet has been posted (edited into the first post).

I purchased some chemicals and they showed up looking great! Big thanks to Texium for putting these for sale.

Dr.Bob - 29-3-2024 at 18:42

Got some stuff from Texium, a great deal. He even had a few things I did not already have, which is rare.

Texium - 21-4-2024 at 11:02

EL and Dr. Bob, thank you both for the good feedback!

I am happy to announce that glassware is now available! See the first post for the spreadsheet. I have some other more niche things that I will begin posting pictures of as well. I'm also planning on putting together some "bargain bins" of things that are either impractical to use (e.g., no ground glass joints), somewhat broken, or just plain weird.

Special Glassware

129: This is a cheap Chinese distillation apparatus. It actually has a bit of a story. It was the first distillation apparatus I purchased about 10 years ago. I christened it with bromine. Didn't use it for much after that because I acquired better equipment. I sold it to Atrum several years ago, and now it has returned to me. The boiling flask takes a 24/29 stopper but I couldn't find it. The condenser's top joint is 14/20. It's a strange little rig. I'm asking $25 for it (clamps and stands are not included).

130: Two cold traps for a vacuum system. Could also be used for gas washing. 130A is 24/40, 130B is 19/38 and has holes in the downtube likely to prevent suckback. $15 each.

IMG_1451 2.jpg - 956kB
131: Miscellaneous 14/20 cow adapters. 131A and 131B require a special vacuum take-off adapter to function, which I don't have available. 131A has teflon-wrapped joints. It seems to be permanently bonded to the glass. Pretty nice, and I've never seen anything like it before. C, D, E, and G are compatible with a 14/20 short path distillation setup. C has 4 3 mL graduated tubes. The graduations are worn off on some and it looks like it was repaired once or twice. I am reserving F to be sold with 133C because it is the only one that fits it, unless someone elects to by 133C without it.

IMG_1452.jpg - 850kB IMG_1453.jpg - 894kB
132A: Complete 24/40 cow receiver setup. Compatible glass stopcock will be provided.

132B: 19/22 cow receiver, missing distribution adapter. Comes with 1 10 mL receiver.

133A: 24/40 400 mm Vigreux column with built in still head. 10/30 thermometer joint. $40

133B: 24/40 Kontes Claisen still head with built-in 200 mm Vigreux column. 10/30 thermometer joint at top of column. $50

133C: 14/20 short-path distillation setup with built-in 200 mm Vigreux column. The column was originally vacuum jacketed, but the jacket is broken. It still functions, just perhaps not as efficiently. 10/18 thermomter joint at top of column. Angled blue glass drip tip to be used with cow. I recommend purchasing 131F cow receiver for compatibility. The other cows I have are too small. $100

133D: 24/40 all-in-one distillation setup. Built-in 100 mm Vigreux column with 10/30 thermometer joint at top. 200 mm West condenser, vacuum take-off. $60

133E: 24/40 200 mm Liebig condenser with built-in still head. 10/30 thermometer joint at top of still head. $30

Old non-ground-glass condensers

Texium - 21-4-2024 at 16:31

IMG_1461.png - 7.5MB
134A: 600 mm Alihn condenser. Two available. $20
134B: 400 mm Alihn condenser. $15
134C: 200 mm Graham condenser. $15

Keep in mind that the 600 mm condensers will be particularly expensive to ship. I consider these a "glassblower's special," because if you have the ability to retrofit these with 24/40 joints, it will increase their value significantly.

$1 Bargain Bin

Texium - 22-4-2024 at 09:19

Here's the $1 Bargain Bin glassware! Every item in these pictures costs $1. Plus, if you order at least $20 of glassware and/or chemicals, I'll throw in one item of your choice for free, while supplies last.

They look like those microfilter funnels. Pregl or something.

Dr.Bob - 25-4-2024 at 11:15

Man, you have almost as much weird stuff as I do. Good luck selling it, if anyone likes Texium's stuff, I likely have more stuff like it, but he has even a few things I have never seen. Would be great for someone in Hollywood trying to make a scientific looking set... Maybe they can use some of it when they make the Breaking Bad sequel, eventually.

Texium - 15-5-2024 at 10:23

Found some volumetric pipettes that I’m willing to sell for $2 each. Note that you’ll probably want to buy these with other items since they’re long and the shipping for them alone would cost a lot more than the item. I have six 15 mL and ten 20 mL ones available.

Also found some new test tubes:

3 cases of 10x75 mm disposable test tubes. Each case contains 250 tubes. I’d be willing to sell these for $20 each.

2 cases of ~15x130 mm screw top test tubes, NO LIDS. 250 tubes per case. I’m asking $30 for each case of these.

dettoo456 - 25-5-2024 at 19:17

Goes without saying, but Texium ships fast, is extremely helpful and fair with items and pricing, and sends glass packaged great. Thanks
