I've been toying with the idea of using some of the sample containers at the lab I work at. We've got all kinds of different tubes.

I can get them for free, and they are often kept in -20C (-4F) or -80C (-112F) freezers. I am dubious about the ones in the first link, I may put them through some testing first. But I think all the others should work great, what do you all think?
