Main features

1 Provide vacuum regulation for reactions such as evaporation, distillation, crystallization, and drying;    

2 The pump head, diaphragm, and valve plate are made of Teflon material, which can be used to extract strong acid and strong alkali gases;         

3 The vacuum can be adjusted, which facilitates precise control of the reaction and can realize conventional distillation of sealed systems;        

4 Use it in conjunction with parallel evaporation to recover solvents and prevent organic solvent waste gas from being discharged into the atmosphere;

5 Oil-free, maintenance-free, long service life.
