Rotary evaporators have wide application in laboratory/pharmaceutical areas nowadays. A rotary evaporator, which often known as rotovap/rotovap/rotavapor, usually 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.

Before you buy a rotary evaporator, please consider below problems:

  • What is the evaporating speed of the rotary evaporator?
  • What is the solvent you want to distillate?
  • What is the boiling point of the solvent?
  • What is the volume of the sample want to be distillated?

We can choose a most suitable model for you after you confirm above questions.
1L/2L and 5L rotary evaporators are often used in lab-scale test; 5L/10L/20L/50L rotary evaporators are often used in pilot-scale test and production.

 

The vacuum degree, temperature of bath and cooling medium can affect its distillation effect.

With recirculating chiller and vacuum pump, the rotary evaporator can be expanded into a high efficient complete evaporator system.
