Product Description

RE-501 5L Rotary Evaporator
RE-501 5L Rotary Evaporator

The RE-501 5L Rotary Evaporator’s maximum capacity is 5000ml, the rotating speed is 5-120r.p.m, and the motor power is 40W. The RE-501 5L Rotary Evaporator is the basis of Lanphan’s existing rotary evaporators. It has a manual lifting handle, a self-developed machinery and a well designed glass component. The location of the glass component can be accurately set. The digital display of the rotating speed and the heating kettle’s temperature can help optimize and control all distillation processes. The new type of fixing mechanism greatly simplifies the operation process of changing the evaporating flask.

The rotary evaporator, also known as rotavap or rotovap, is a common lab instrument used in chemical laboratory. It’s mainly adopted to distill a large amount of volatile solvents continuously under the negative pressure. It is capable of separating and purifying reaction products especially for the concentration of liquid extract and distillation of receiving fluid during the chromatographic separation. As the evaporator is vacuumized, the boiling point of the solvent to be distilled decreases. In general, the component distilled from the sample is the target component in the chemical research, such as extracting some natural component from organic synthesis sample. Generally, the rotary evaporator is used to separate components with low boiling points, such as ethane and ehtyl acetate, which are liquids at room temperature and normal pressure. Furthermore, some component in the sample can be removed through standard operation.
