[Nhcoll-l] shelving in wet collection

[Lennart Lennuk]

Most of our fluid preserved collection is in 100, 300 and 500ml jars.
This far I have been asking the shelving company for perforated steel shelf plates finished with powder coating
but the company is trying to convince me to use the shelving shown on the picture in my previous letter.

Best!
Lennart

Hi Lennart,

to me this looks like storage for lab consumables, and even for this purpose you may need to prefer (closed) chemical cabinets instead of open storage (depending on the lab chemicals).

For ordinary fluid preserved collections, the recommendation is not to go below 75 ml fluid volume per container. Depending on the quality of the closures and the environmental settings in the storage area, containers below 75 ml may dry up fast, if the seal/closure is bad. Depending on the number of jars, you would need to adjust your monitoring regime to spot evaporation losses and to prevent damage to objects stored in smaller containers.

If you would need or want to store specimens in smaller volumes, it would make more sense to use closed cabinets with drawers. Ideally, as Simon recommends, the drawers are equipped with grids or boxes that stabilise the small vials or tubes. We have equipped our cool and refrigerated storage with such drawer-cabinets<https://www.lista.com/en/products/drawer-cabinets/>

Hope this helps
Dirk

Hi

Do you have any experience using this kind of shelving in wet collections?
I am worried about load-bearing capacity and also the stability of little jars.
Is it ok to place a rubber mat under little jars to maintain the stability?
