What Affects Working Efficiency of Rotary Evaporator

The rotary evaporator is a commonly used instrument in the laboratory, which is composed of a motor, a distillation flask, a heating pot, a condenser tube, etc. It achieves a rapid evaporation effect through heating and rotation, and the evaporated material is recovered from the solvent by the condenser to achieve purification and separation. It is widely applied in chemistry, chemical industry, biomedicine and other fields.

Four factors that affect the efficiency of vacuum rotary evaporator:

1. Vacuum

The pumping capacity of the vacuum pump, the tightness and service life of the gasket, the fit degree of the glass grinding port, and the control of the vacuum degree;

2. Heating temperature

Heating capacity and stability of water/oil bath;

3. Cooling capacity of condensate

Cooling capacity of cooling water circulation tank, circulation power and head of cooling water circulation tank;

4. Rotation ability

The stability of the rotating motor, the concentricity of the glass shaft and the host.

Digital rotary evaporators are widely used for large-scale concentration, drying, extraction and recovery of samples, especially for the concentration and purification of biological products that are easily decomposed and denatured at high temperatures. It is an ideal equipment for scientific research experiments and industrial mass production in chemical, pharmaceutical, food, environmental protection, universities and other fields.
