Rotary evaporator manufacturer supplier price for sale, ZZKD professional rotary evaporator includes R series rotary evaporator and RE series rotary evaporator, please contact us for specific specifications and model parameters.

The rotary evaporator is a device that uses a rotary evaporation flask (flask) to increase the evaporation area while being placed in a water bath under a reduced pressure while heating, and the solution in the bottle is diffused and evaporated. It is an ideal basic instrument for chemical industry, pharmaceutical industry, universities and research laboratories for the manufacture and analysis of experiments, such as concentration, drying and recycling.

Rotary evaporator structure principle

  The distillation flask is an eggplant-shaped or round bottom flask with a standard ground port, connected to a pressure reducing pump via a highly refluxing serpentine condenser, and the other opening of the reflux condenser is connected to a receiving flask with a grinding port for The organic solvent that is evaporated is received. There is a three-way piston between the condensing pipe and the decompression pump. When the system is connected to the atmosphere, the distillation flask and the liquid-receiving flask can be removed and the solvent is transferred. When the system is connected with the decompression pump, the system should be reduced. Pressure state. When using, depressurize first, then start the motor to rotate the distillation flask. At the end, stop the machine and then pass the atmosphere to prevent the distillation flask from falling off during rotation. As a heat source for distillation, it is often equipped with a corresponding constant temperature water tank.

Rotary evaporator working principle

  By electronic control, the flask is rotated at a constant speed at the most suitable speed to increase the evaporation area. The evaporation flask was brought to a negative pressure by a vacuum pump. The evaporation flask was heated in a water bath while rotating at a constant temperature, and the solution in the bottle was subjected to heat diffusion evaporation in a rotating flask under a negative pressure. The rotary evaporator system can seal the pressure to 400~600 mmHg; the solvent in the distillation flask is heated by a heating bath, the heating temperature can be close to the boiling point of the solvent; and the rotation can be performed at a speed of 50-160 rpm. The solvent is formed into a film to increase the evaporation area. In addition, under the action of a high-efficiency cooler, the hot vapor can be quickly liquefied to accelerate the evaporation rate.
