[Nhcoll-l] Holotype specimens on SEM stubs

We use single-stub storage tubes for long-term storage of SEM type material, coated and uncoated:

These are sufficiently airtight that their internal conditions will equilibriate, and we keep them in cabinets within our normal collection space, which is 50-65 degrees F and 50-70% rH.
Of course, this likely will prove too expensive for large-scale storage, in which case a dry chamber or dry room is likely to be more economical.

External.
Hi All,

We have received a request to deposit a holotype of a protist into our collection, but the specimen was used for SEM. We have desiccation chambers for storing SEM stubs for working research, but I wanted to know if there is a best practice for long-term storage of SEM specimens that are designated holotypes/type material. Do other collections utilize sequestered chambers for type material, or is there another way to store unicellular type material that was coated?

Thank you for all of your input and suggestions,

Katrina
