[Nhcoll-l] Drums, etc

Dear all,
I'm curious about ways of separating specimens in the steel tanks, as specimens that are too large for glass jars often do not fill a stainless steel tank. To maximize use of the tanks, we're looking into how we might put several lots in one. It raises many issues, shared preservative, physical contact/compression, etc... 
Thanks for your insight, 
Nathalie

I agree with Andy, the Delta Design steel tanks are vastly superior to any others on the market.

I also second his choice for the "Gamma Seal lid" containers. Laura Abrazinskas has used these at the Michigan State University Museum for years with great success--they seal really tight.

Keep all polyethylene (usually stamped PE on the bottom) out of sunlight and interior UV sources (such as fluorescent lights), as exposure to UV will cause the PE to deteriorate over time.

We too use metal tanks from Delta Designs (we have found that they are superior to Steel Fixtures tanks) – see attached.  They come in three sizes and can also be custom made to pretty much any size.  You may be able to shop these designs around in Australia to see if there is someone there who would make them for you.  The drawback is that these are pretty expensive – as attached from some time ago.  Steel prices and supply chain issues have increased these I am sure.

As a cheaper alternative we have had some success with using these in the field and they are very sturdy and leak proof.  We have shipped specimens back from the field in these without issue.  They too come in various sizes and have a gasketed lid and indentations for carrying - https://www.chewy.com/gamma2-vittles-vault-pet-food-storage/dp/101384

I would however warn you off these - https://www.universityproducts.com/polycarbonate-storage-pails-for-wet-collections.html.  Our herpetology division played around with these some and they are not alcohol safe – they crack over time and do not seal well at all.

Hope that helps

Andy

 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
