Alternatives For Rotovap How to use a Rotary Evaporator - University of California ... Apr 01, 2010 3. A metal or Keck clip is used to secure the flask and the bump trap. The green one shown below fits 24/40 ground glass joints. Similar blue clips fit 19/22 joints and the yellow ones fit 14/20 joints, which will most likely used in the lab.
Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.
Apr 10, 2019 CentriVap holds up to 132 samples of up to 25 mL in size.

Rotary evaporation is accomplished using a rotary evaporator, also known as a rotovap or rotavap. It is a commonly used technique for separating a compound of interest from a low-boiling solvent, such as an organic, inorganic, or polymeric substance. Separation is accomplished by heating a mixture of solvent and compounds inside an evaporation ...

The motor in the rotovap turns the flask rapidly, providing a greater surface from which evaporation can occur and speeding up the process. Cooling coils in the rotovap condense the vapors and drop them into a collection flask so that they can be recycled or properly disposed. The roto-vap is connected to a vacuum source, and again, this speeds ...
