Taylor Wharton VHC 35
35L / 9.2 gallons
Double walled steel.
Large neck, with specimen cannisters
4 month (130 day) static holding time.
Bought them as a group, but I only need one.
All are university surplus, and in good condition.
$275 - have 3 available. All on casters.
I’m guessing that price is for each one? Or is it for all three?
I wonder if this is something that @Team_Science would be interested in purchasing for anything…???
It is each - though I’d be open to an offer on more than one.
can we keep liquid Nitrogen at the space?
It is not flammable, so the fire marshall shouldn’t have a problem with it. 
Aside from cryoburn, I’m not aware of any major safety issues with storing it in an approved vessel. It does evaporate over time, though - the static holding time is how long it would take for a full tank to empty itself.
At Texas A&M they had a LN2 dewar explode due to an issue with the safety valve. Not common, but it can happen…
These are not pressurized (hence the relatively short storage life). They are float tops, so I cannot begin to imagine how that could happen with these.
DMS already has a dewar, so yes. If not I can loan you 4 or 5.
That’s good to know, Thanks!
It’s probably a good time to remind others reading this thread that there are three used dewars for sale at what seems to be (according to a quick search on Google and eBay) a pretty decent price.
Science would jump on this except that we already have one and I couldn’t ever really see us needing more than the one… it is missing its cap though
It’s just a reference picture - but I’m not sure what cap you mean. What cap is missing?
We have a liquid N2 dewar, but it’s missing the cap/plug that sits on top. It’d be like the blue piece in your pic
Ah, that makes more sense. I thought you were saying that ours was missing the cap.
Hello - do you still have these for sale? I am interested in buying one. Thanks!
Since this old thread floated to the top and someone mentioned this failure, I thought I’d link to this information about it. It’s not just that the pressure relief valve failed, it’s that after it failed someone “fixed” it by simply putting a metal plug in its place. And now, I leave you with the excellent writing of Derek Lowe (if you haven’t poked around his blog before, it’s a real treasure).
Wow, what a fantastic descriptive story. A must read. Here’s a snippet…
“The explosion blew all of the tile off of the floor for a 5’ radius around the tank turning the tile into quarter sized pieces of shrapnel that embedded themselves in the walls and doors of the lab.”
