So... anyone in the UK likely to be discarding one that meets minimal school safety standards (working interlocks and a full shield) and takes 15ml tubes? Or a microcentrifuge that takes 1.5ml and 2ml tubes - not ideal, but better than nothing?
If I was in the USA I would have no problems, there seem to be dozens on eBay.com. eBay.UK unfortunately sees a lot less, and they go for much higher prices.
I should add that we can make use of lots of other types of lab equipment too, within reason. A nice mass spectrometer (if not too big), some geiger counters, etc. etc. Can't actually afford to pay for it, but we could sure as hell use it.
