Edwards has expanded its range of nEXT turbomolecular pumps with two larger models that provide faster pumping performance and excellent compression ratios for longer cycle times and lower ultimate...
1. Basic types and characteristics.
Water ring pumps can be divided into the following types according to different structures.
■ Single-stage single-acting water ring pumps: single-stage means th...
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...
High vacuum manual angle valves, swith manual rotation of the handle to drive the opening and closing of the valve plate. with the advantages of smooth action, small size, reliable use, good sealin...
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...
