Rotary vane vacuum pump for rotary evaporator. This series of pumps have been improved on the 2XZ type. We adopt foreign advanced technology and experience. It is used to pump water vapor in sealed containers, so that the containers are in a vacuum state. It can also be used as a front-stage pump for high vacuum or ultra-high vacuum equipment.
The air vacuum pump is a venturi-type AC pump that eliminates moisture from air conditioning systems, making it safe and easy to add refrigerant. The air vacuum pump is easy to operate and pulls full vacuum within two minutes of being connected to an air line. Includes 1/2 .
By utilising a pump to place the rotary evaporator under vacuum, distillation efficiency is greatly improved. By reducing the pressure within the glassware of the rotary evaporator solvents can be evaporated off at lower temperatures ensuring the bath can be kept at a safer temperature.
Efficient solvent distillation requires vacuum balanced to achieve sufficient pressure reduction and molecular flow without losing sample or overrunning the condensing capabilities of your rotovap. When selecting a vacuum pump for rotary evaporation: 1. Select a chemical resistant dry diaphragm vacuum pump for routine evaporations. 2.
