Rotary evaporator is a device used to separate solvents through evaporation in a partial vacuum. It is widely used in chemical, chemical industry, biomedical and other fields.
Process for rotary evaporator:
Firstly, with sample placed in evaporation flask, evaporation flask keeps rotating to facilitate evaporation by enlarging evaporation area.
Secondly, solvents evaporated from sample are transported into condenser and then condensed into liquid from air.
Thirdly, the liquid solvents flow into receiving flask for users to get.
Tips for rotary evaporator:
- In the beginning, remove gas from the sealed equipment to get a partial vacuum before rotate the evaporation flask to prevent evaporation flask falling down.
- In the end, stop the rotation before stop vacuum pump to prevent evaporation flask falling down or suck-back.
- Make sure there is water or oil when thermostatic water or oil bath is working.
- Receiving flask: a device used to collect solvents.
- Condenser: a device used to condense gaseous solvents matching with chiller.
- Motor: a device powered by electricity used to supply motive power for the whole rotary evaporator equipment.
- Evaporation flask: a device used to contain sample and keep rotating to facilitate evaporation by enlarging evaporation area.
- Thermostatic water or oil bath: a device used to heat evaporation flask.
- Thermostat control: a device used to control the temperature of thermostatic water or oil bath
- Vacuum pump: a device that removes gas from sealed equipment to leave behind a partial vacuum.
- Chiller: a device used to cool equipment .
