Rotary Evaporator

Rotary Evaporator

A rotary evaporator (sometimes abbreviated to rotavap) is a piece of equipment primarily used to remove solvent from a sample through “evaporation under reduced pressure”. The presence of reduced pressure in the apparatus causes the solvent (in the round bottom flask) to boil at a lower temperature than normal.

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts. The main components of a rotary evaporator are: 1. A motor unit that rotates the evaporation flask or ...

What is the purpose of using the rotary evaporator? - Lab Instrument Manufacturer

A rotary evaporator works by the general assumption that at each given time, the boiling point of the solvent in question is much lower than the boiling point of the liquid surrounding it. As the boiling point of liquids slowly reduces when you decrease their pressure, it allows the solvent to be vaporized at lower temperatures than their ...

Buchi 20/40/60 rule for Rotary Evaporators Optimal Distillation parameters for a rotary evaporator vary according to solvent in use: 1. Set water bath temperature to 60oC – It does not need to be higher! 2. The cooling water temperature should be below 20oC. 3. Adjust the needed vacuum for a solvent boiling point of 40oC according to list below.

Mar 01, 2021 Pressure Is Reduced. To begin the process of rotary evaporation, a solvent is placed in a round-bottomed flask in the water bath of the rotary evaporator system. The system’s pressure is then reduced below atmospheric pressure through the use of a vacuum pump. Reducing the pressure in the rotary evaporator has numerous benefits.
