Since Scimad is not running well, if you want info or to buy or ask about stuff, email me at craigslistinnc@gmail.com (my public spammed email) and I
will reply from my normal email. I have had a time getting into scimad lately...

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.
