[Nhcoll-l] Drums, etc

[Dirk Neumann]

Hi Tonya,

if you consider rectangular stainless steel tanks, the design of the closure of the tank needs some attention to avoid condensation-moisture to get into contact with the seal/gasket of the tank.

An inner T-shaped welding serving as drainboard keeps the seal dry and prevents deterioration. Regarding the fumes, you could consider flexible extraction arms like these https://www.nederman.com/en-au/products/capture-and-extraction-units
For the ventilation of the room where you keep the tanks one solution could be to design the entire room as a wet-lab workspace, i.e. to consider higher ventilation rates (which of cause has pros and cons). But this setup in principle is used in the tank room at the NHM in London, the USNM has chosen a similar set up. Might be worth asking the colleagues there directly, in case they wouldn't chip in to this thread.

Hope this helps
Dirk

Hi again,

I do have one question regarding stainless steel tanks, for those of you who use them. Even the smaller ones I assume are quite heavy. Where do you store them, and how do you access them? Do you have specially ventilated areas for them, etc? Right now we try to do our work in a fume hood because of formalin fumes (some of our more historic specimens have very high formalin concentrations). I would love to know how or if people deal with this in their daily operations.

Thanks again!

Tonya

Hello all,

I am trying to figure out a nice solution for housing larger specimens. Right now we have them stored in either old canning jars (really rammed in, not great), or in buckets (don't seal properly and aren't archival) or drums with rubber (?) gaskets (they seem to leak when you tip them, no matter how much they are tightened). I really want a good, leak-proof or at least minimising solution, and I feel I haven't found it yet. It's really frustrating - the drums are even made for brewing, so you would think they would form a nice seal, but they don't seem to. If any of you have a solution you like for housing medium to larger specimens (and I actually mean anything over a 2L jar), or a solution for making gasketed drums work, I would love to hear it.

Thank you!

Cheers,

Tonya
