I have what I need to do my job. There’s always something else though. I found myself wishing today.
What I’d like is something to monitor my rotavap so I can see when it is done. So I know when it is time to get up from my desk and add more solvent or take it off. I don’t know how many times I’ve been about ready to go home, but not until this stuff has had all the solvent removed. I’m imagining a little web cam type thing, with a feed to my computer. I can look to see if it has bumped or if it is actually removing the solvent properly. Anyone else ever done that? Left a flask on the rotavap over a seminar and come back to find it has removed precisely 3 mL out of the 250 mL in the flask. And if I increase the vacuum just a tiny bit, it is suddenly flying off.
And when it is done (but not before) I can spring into action, do what needs to be done and then get back to updating my note book or reading papers or other important business that I conduct from my desk.
Oh, and a way to alert me when my TLC is done. That would be great too.
(and right after I pressed submit on this post, I went into the lab and found my solvent had hardly gone down at all – see how useful this invention would be?)
