Science equipment looking for a home

I have another box of tall dewar flasks for sale now. There are basically three of the larger ones, nearly identical, about 2L, I would guess, and three smaller ones, about 1L or less capacity. The 1L ones are a little over 12" tall, about 2.5-3" ID and about 3-3.5" OD. These are about the minimum size needed for a normal sized to small vacuum trap. I'll sell these for $40 for the one that is wrapped in tape, $50 for the nicer ones. These start at $100 on Ebay, $200 new.

The 2L ones are about 14" tall, ID of 95 mm (~3.5") and an OD of 140 m (~5"), inner depth about 300 mm (~12"), overall hight about 350mm (14"). These will hold a med to large vacuum trap and enough coolant to keep it cold overnight in most cases. They have small site holes in the alumnium sides, so you can check on the contents. These were made by HS Martin in Vineland, NJ, home of most US glassblowers. I'm asking $200 plus shipping on Ebay, but will only ask $125 on SciMad. These sell for about $500 new now.

Here are some photos of what is left in my 14-20 glassware. I'm making one kit for someone currently, mostly from the first photo, but I have enough to make a second mostly complete kit, plus three boxes of extra condensers, columns, flasks, and more. If anyone is interested, this is what I have left, plus about 3 more boxes of pear flasks, multinecks and other odd bits that are still packed in a box. I typically make a kit for $80-100 for a basic set of 5-6 rbfs, dist head, claisen and curved vacuum adapters, condenser, and more. But I can add much more or make a small one.

Here are three manifolds that I just found while looking to se what I had let for them. They are all not quite complete, but I likely have the pieces to fix them, just wanted to show what I have, if you are interested, please let me know and I can try to find whatever pieces are needed to complete them. Part of which inlet and outlet type you would want. I have lots of shperical joint adapters and fittings. I have not researched prices much yet, these would be a lot new, but worth less as used, so make me an offer, and I can see if I can find whatever pieces you need to make it complete. Third one will be on the next post due to photo size limits.

Third manifold photos:

Next up are some sohxlets, vacuum traps, random things, and more. I have many more Soxhlets, but just found these huge and medium size, like new, these are just a few, I have more. The prices are in the spreadsheet for them. The traps, make me an offer, I have two huge ones with little 1/4" nipples (asking $60), and one with spherical inlet/outlets (asking $25), again I can also find the fittings to match those joints. Then a few odd items, make me an offer. I also have 6 250 ml erlenmeyer flasks with screw tops, I think they work with caps from 4L bottles, I am trying to find some to test that. They would be $4 each or all 6 for $20.

Here is another batch of 14-20 photos, these, along with the ones a few posts back, are much of my 14-20 materials. But I am sure I have more stuff that I will find later, just much duplicates this.

And more 14-20
