Choosing the right condenser - Chemistry Stack Exchange

An Allihn Condenser on a rotovap would run the risk of breaking/create undue stress the bearing junction. Nearly 5 Feet and (Roughly - not certain but HEAVY) 35 lbs of condenser, containing 15 lbs of coolant = roughly 50 lbs, on a slant.

BHO with old trim - THCFarmer

Feb 15, 2016 Nov 9, 2012. #4. I'm going to start doing some tests by re-hydrating old dry trim and blasting it to see if it comes out the same as naturally fresh trim. I know the trichomes also change but I think the darker oils just come from dry trim that breaks down really easy. If you lock up everything in water (besides the trichomes since they are not ...

Mar 07, 2012 Winterizing: When using non polar solvents like butane and hexane, some non-polar waxes, fats, and lipids are extracted as well. An easy way to get rid of them is to simply re-dissolve the non-polar extraction in 190 proof (~95.5% azeotropic) polar ethanol and stick it in the freezer for about 48 hours at -18C/0F, for the waxes to coagulate.

The RotoVap Limitations. For years, the industry standard for solvent recovery has been the rotary evaporator, or otherwise known as the RotoVap. A generic 20L RotoVap has a recovery rate of about 1.5 gallons per hour. For small-scale setups, this may suffice, but large-scale manufacturers have been forced to run multiple RotoVaps.
