I have a single neck 1 L RBF 24/29, a 250mm 24/29 Alihn condenser and (maybe) a 500ml sep funnel to swap for stuff if anyone's interested?

NEMO, how much for 500 g KOH + shipping to CA?

I am having a mare getting a quote, no idea about shipping yet but the 500mg is around $4

Actually I might have a better contact for you over there.

NEMO I’m in the same boat as ninhydric1, I’d like some KOH but I’m in CA so shipping is probably not practical. If you have a local solution and it’s not too much trouble I’d appreciate it, thanks!

I have an extra 24/29 distillation head, thermometer adapter, and straight path condenser, but there is a chip in the condenser, and they are just cheap Chinese and heavily used. I think I have a lightly used 24/29 105 degree vacuum takeoff adapter around here somewhere... I'm somewhat interested in DMF and acetic anhydride, but seeing how you can get a distillation setup from Nanshin for around $30 I think, you probably don't want my old glassware. But feel free to drop me a message if you would like to trade a small amount of one or both.

You might want to check with Dr. Bob; he sometimes has some 24/40 and 19/22 items.

I actually need a small 24/40 pressurized addition funnel (125-250 mL), a small 24/40 Squibb funnel (125-250 mL), and a small 24/40 glass frit (60-350 mL). I'm somewhat interested in powder addition funnels with an auger and pressure equalizing arm. I'm looking for bulk potassium nitrate since all the local sources seem to have dried up. I have lots of basic bulk chemicals and a few hard-to-find exotics, but I'm not likely to give up the exotics except for other exotics.

I've been thinking about doing a bulk potassium iodide buy. Would anyone be interested in $70 kilograms?

I have an unopened 4l of ACS Acetone from Sigma stock# 179124-4L, a little formic acid 95%. Also a Clay-Adams Safety-Head Centrifuge / Model No. 0011
I’m sure I’ll add a few more things to this as well.

ninhydric1, KOH is fairly easy to find if you know where to look.

Artisanal soap makers use it. So somewhere, probably close to you, KOH is hiding in plain sight.

Would anyone be interested in an older flash evaporator? I may be looking to get rid of it if I decide I won’t have much use for it.

Do you still have the KMnO4, the erlenmeyers and the Na2S? I would be interested in two 250ml elrlenmeyer flasks, 200g of potassium permanganate and 100g of Na2S. I am willing to trade multiple items or to pay. U2U me if you'd like to sell/trade.
