What is the best way to evaporate diethyl ether from a mouse plasma extaraction? I am trying to extract indole from the mouse serum, using diethyl ether, and my sample size is very small (< 1 mL). Would it be possible to evaporate off the diethy ether by just putting it under a fume hood?
Our rotovap can fit 45 mL tubes at the smallest and it's not under a fume hood so I'd prefer to not have to use it. Would I need to evaporate under a flow of nitrogen?
