This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure...
Mass Flow Controllers(MFC) provide precise measurement and control of the mass flow of gases.
I. What is the difference between a MFC and a MFM?
Mass flow meter(MFM) is a kind of instrument that ...
The molecular pump is a vacuum pump that uses a high-speed rotor to transfer momentum to the gas molecules so that they gain directional velocity and are thus compressed, driven towards the exhaust...
