Rotary vacuum evaporators are efficient laboratory distillation units for applications like standard solvent distillations, concentration of reaction mass or solutions, separation of solvents from extracts, crystallization and powder drying.

Filtration


Connect the side arm flask to a vacuum source. Always use thick-walled tubing, since Tygon tubing will collapse under reduced pressure. Wet the paper with a small amount of the solvent to be used in the filtration. This causes the paper to adhere to the plate and keeps materials from passing under the paper during filtration. Turn on the vacuum ...
