Speed adjustment stops pump completely when vacuum level is reached and runs intermittently at a low speed to hold vacuum constant. Intermittent operation results in increased diaphragm performance life, low energy consumption, and noise and vibration reduction. Operates without vacuum valve. 3-stage 3-stage pump can distill high boiling point solvents such as DMF and DMSO at low bath temperatures. Chemical resistant.Specification: Item: Rotary Evaporator VacuumPump Type: rpm RegulatedNumber of Motor Stages: 3Vacuum Pressure: 2 mbarSuction: 1700L/hr.Watts: 160Height: 7-45/64"Length: 6-37/64"Width: 9-19/64"Features: Even If The Gas Ballast Valve is Open An Excellent Ultimate Vacuum is Reached When Working with Easily Condensable Vapors, This Makes Distilling High Boiling Point Solvents Such As DMF or DMSO Possible At Low Bath Temperatures"
