Vacuum system is widely applied in the processing of exhausting, evaporating in chemistry, biology, pharmacy laboratory. It mainly used in combination with parallel evaporation, rotary evaporation, vacuum concentrator, or vacuum drying oven.
Feactures
1 Providing vacuum adjustment for evaporating, distilling, crystallization, drying, etc.
2 Pump head, diaphragm, and valve adopt Teflon, which can extract highly acidic and alkaline gas.
3 In order to control the accuracy of reaction, the vacuum degree can be adjusted. Conventional distillating can be realized in a closed system.
4 It is used with parallel evaporation as well, which can prevent waste liquid of organic solvent discharging into the atmosphere.
5 Oil-free system with long service life.
