Laboratory Analysis Instrument

Linear Stand and Round Stand

The evaporation bottle rotates at a constant speed, the water bath is heated at a constant temperature, under this condition: the material forms a large area of uniform film on the inner wall of the evaporation bottle and evaporates rapidly, which can improve the evaporation efficiency under vacuum conditions (need to connect the vacuum device), and the solvent steam is cooled into a liquid when the glass condensation coil (need to connect the cooling device), and is recovered in the collection bottle.

The use of this series of products requires supporting vacuum devices (circulating water, rotary vane, diaphragm and other vacuum pumps), cooling circulation device composed of system devices.
