Subject: Re: Consolidating historic sample collections
I suggest using glass scintillation vials.  These are cheap, come in a variety of sizes and come in boxes that are amenable to cataloging and storage.  I used them for all of my synthetic samples in graduate school.  My Chemglass representative recently told me that they now have varieties with teflon lined lids.  You can rotovap samples in these as well using a septum and a needle, so you don't need to store items in round bottom flasks.  The 24/40 septa fit nicely over the end of the vial, with the other end fitting into a 14/20 male-end bump bulb.  Insert a needle before hooking in up, and boom, you can rotovap samples directly in the vial.

Subject: [DCHAS-L] Consolidating historic sample collections

We have chemistry faculty members who have historic collections of materials 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 question arose whether what the best practices are for collecting and cataloging these materials into easily identified and managed collections. For example, 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 and that I would forward the question to the collective intelligence. Any good experiences or ideas out there?

Thanks for any information.
