Laboratory digital vacuum pump regulator vacuum controller

Review

This Vacuum controller with excellent performance, it  can control the vacuum degree precisely .It can connect with the rotary evaporator to control the rotary evaporator’s vacuum degree and then improve the recovery rate of low boling point reagent like: Methylene chloride,benzene, Trichloro ethane,and ethanal etc .Vacuum controller can replace the inert gas so that sample is not affected by oxidation and contamination,which avoid reducting the sample concentration.
