  1. Hey still looking for any help on this final step in my extraction procedure. I've been carrying out the other steps and now just have a lot of methanolic and ethanolic extract waiting to be isolated. 2 interesting things I've noticed that might be of help. 1) when I increase pressure to above 20inHg the solvent starts to appear in the condensor. this may be a solution to my problem, but the vacuum that I am using is very finicky at this pressure and oscilates between extremely high negative pressure or reverts back to around 10inHg. Is 20inHg an acceptable pressure for a system
  2. Hey, I'm having a problem isolating a plant extract out of methanol. The solution is about 15% extract by mass. My institute has a rotary vacuum evaporator, however, I have been attempting to use this to no avail and no one here is especially experienced with the apparatus. I really don't know what the problem could be - here's my trouble shooting thus far: vacuum pressure on the system is 10inhg; none or very minimal leaks; water bath temp first attempted at 60C won't even evaporate off at 90C; tried different speeds of rotations; condensor is running. Yesterday it started workin
