ZZKD is expert in lab instruments, Rotary evaporator is one of our main products,such as re-201d rotary evaporator, re-501 rotary evaporator and so on.

Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is that under vacuum condition, the temperature is heated at a constant temperature, so that the rotating bottle rotates at a constant speed, and the material forms a large-area film on the bottle wall, and evaporates efficiently. It is especially suitable for the concentration and purification of biological products that are easily decomposed at high temperatures.
Rotary evaporators include small volume rotary evaporator and large scale rotary evaporator. When using the rotary evaporator, pay attention to the glass parts should be handled gently, cleaned, dried or dried before loading. A vacuum grease is applied to each grinding port, sealing surface, seal ring and joint before installation.

Before turning on the power, turn the speed control knob to the left and press the power switch. After the indicator light, slowly turn to the right to the required speed. Generally, the large evaporation bottle uses low speed or medium speed, and the high viscosity solution uses lower speed. It is suitable that the amount of the solution is generally not more than 50%.
