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.

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.
