Product Stories from Liquids and Gas Handling

The nEXT range of turbomolecular pumps from Edwards, which are used to create the vacuum systems for laboratory applications such as mass spectrometry and electron microscopy, have been designed to provide high vacuum performance in a compact size. The range offers a wide variety of sizes and variants giving OEMs and end users a greater choice and the flexibility to tailor the most appropriate vacuum solution to meet their individual needs.

The nEXT pumps offer reliable, high-speed, high vacuum performance, and are available in three sizes offering a choice of true 240, 300 and 400 litre per second N2 pumping speeds. Each is available in three variants: the S-Type is a simple turbo; the D-Type combines turbo and drag stages; and the T-Type adds Edwards' unique fluid dynamic stages and the option of additional booster ports for increased system rationalisation. Custom interface splitflow variants are also available in three sizes for further vacuum system optimisation. 

The pumps feature a field replaceable oil cartridge and bearing assembly and the user is notified as to when service intervention is required.
