RE-2002 20 Liter Rotary evaporator are distillation units that incorporate an efficient condenser with a rotary flask system. The evaporating flask capacity is 10L,as the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface. This gives a very large surface area for evaporation that is effected by heating from the accessory water or oil bath.

The rotary evaporator functions by subjecting a mixture to heat which removes the volatile components fast by the action of vacuum & rotation. The volatile components are condensed & collected. By this way, Temperature sensitive materials(such as beta-carotene) can remove solvents from the mixture without damaging the product. Rotary evaporator is faster and easier  than steam distillation which needs more time and labor, so it is widely used for condensation, crystallization, separation, recovery in laboratory experiment and pilot production and has become one of the necessary necessary instruments in the chemical industry, pharmaceutical industry, universities, and research laboratories and other units etc.

The rotary evaporator is the essence of domestic and foreign similar products, and sets our company successful practical experience. We have developed 10 liters, 20 liters, 50 liters large capacity rotary evaporator. And the equipment’s design follows efficient, practical, economic principles to meet customer’s requirements maximally.

Features:

  • International advanced EL gas-tight system keeps high vacuum degree. Gas-liquid separator, no reflux.
  • Double condenser, collection rate over 95%.
  • The rotating flask is easy to install and setup.

Application

Rotary Evaporator is a laboratory common equipment which composed of motor, distilling flask, heating bath, condenser, receiving flask and so on. It’s mainly 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.

It’s the ideal tools for lab applications, such as:

• Concentration of solutions;
• Reclamation of solvents;
• Vacuum drying of wet solids;
• Essential oil extractor;
• Efficient and gentle removal of solvents from samples.

Mainly used in Pharmaceutical, Biotechnology, Chemistry, Food Industry and laboratory, ect.
