I have to agree with Kristi. I did the same thing in grad school and had great success with it. The Teflon-l ined caps worked well with a lot of the solvents I used. And there was another kind I used (it might have also been Teflon) that worked really well with DMSO. I think we used the VWR brand and the boxes were easy to categorize and you could stac k 2-3 in a regular lab drawer.

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 stor age. 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 be fore hooking in up, and boom, you can rotovap samples directly in the vial.

historic sample collections
We have chemistry faculty members who have histo
ric
collections of materials they have developed themselves that are at the bot
tom
of the round bottom flasks. These collections take up a lot of space and ar
e
hard to manage in accordance with good practice. During a discussion of thi
s
concern, the question arose whether what the best practices are for collect
ing
and cataloging these materials into easily identified and managed collectio
ns.
For example, are there well plates or other systems in place that are
appropriate for collecting large numbers of small quantities of materials?<

Thanks for any information.

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 good
experiences or ideas out there?
