Ralph,
Some in the pharmaceutical industry moved from having solid sample collecti
ons to solvated collections in the 1990's. Concentrated historical samples
were stored in DMSO in glass vials. Well plates were used for large collect
ions, and as stock plates for high throughput screening.
There are the usual safety issues with handling materials in DMSO, but I th
ink the glass vials worked well.
Maybe someone with more recent experience could speak to the long term stab
ility of solvated collections in plates, and if there are newer more effici
ent systems than this.

Subject: [DCHAS-L] Consolidating historic sample collections
We have chemistry faculty members who have historic collections of material
s they have developed themselves that are at the bottom of the round bottom
flasks. These collections take up a lot of space and are hard to manage in
accordance with good practice. During a discussion of this concern, the qu
estion arose whether what the best practices are for collecting and catalog
ing these materials into easily identified and managed collections. For exa
mple, are there well plates or other systems in place that are appropriate
for collecting large numbers of small quantities of materials?
I said that the wisdom of DCHAS-L might have some information about this an
d that I would forward the question to the collective intelligence. Any goo
d experiences or ideas out there?
Thanks for any information.
