I'm looking at buying a used rotary evaporator, because the price for a new device is quite steep for a hobby device. Now I was wondering whether that's a bad idea, considering the fact that there's a good chance they have been used to extract highly volatile chemical substances in a lab.
Is this really as unsafe as I think? Is there a reliable way to clean the glassware of such a second hand rotavap? How do the lab guys do this, since I guess they don't want to mix their chemicals with those from previous experiments either?
thanks!
