The quality of the rotary evaporator will seriously affect the work efficiency, so how to choose a rotary evaporator with good quality and cost-effective.ZZKD is professional Lab equipment manufacturer in China,rotary evaporator is one of our main products and include:2L rotary evaporator, 5L rotary evaporator, 10L rotary evaporator, 50L rotary evaporator.

First of all, we must look at several key points that determine the quality of the rotary evaporator:

1.A lifting motor is installed inside the rotary evaporator. This device can automatically lift the flask to a position above the heating pot when the power is cut off.
2.Reduce the centripetal force and friction between the liquid sample and the evaporating flask, because the liquid sample forms a liquid film in the evaporating flask, and the heated area will have a certain friction.
3.The force generated by the rotation of the sample effectively inhibits the boiling of the sample.
4.About the motor heating up
The motor of the rotary evaporator adopts three-phase electricity, 220V special motor, E-class insulation, and the motor winding group adopts polyester high-strength enameled wire. When the altitude does not exceed 1000 meters and the ambient temperature does not exceed 40 ℃, the surface temperature of the continuous use motor will rise high.
(The difference between the motor surface temperature and the ambient temperature), as long as it does not exceed 45°C, it is normal. If the temperature rises above 45°C, check the relevant transmission lubrication system.
 
5.Four factors affecting the evaporation speed of the rotary evaporator:
(1) The temperature of the water bath;
(2) The vacuum degree of the rotary evaporator;
(3) Whether the condensation recovery unit is efficient;
(4) The rotation speed of the sample bottle.
