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. Kathy Kathryn G.

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. - Ralph Ralph Stuart, CIH Environmental Safety Manager University of Vermont Environmental Safety Facility 667 Spear St. Burlington, VT 05405 rstuart**At_Symbol_Here**uvm.edu
