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.

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.
