Turbomolecular Pumps for Mass Spec and Electron Microscopy Applications

Edwards has launched a new range of turbomolecular pumps that provide high vacuum performance in a compact size for laboratory applications such as mass spectrometry and electron microscopy. The innovative nEXT pump 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. This enables nEXT pumps to be maintained easily as users can carry out

servicing in-house, which reduces the cost of ownership. The efficient pumps have low power consumption and also feature a standby mode, which allow users to make further energy savings.

nEXT pumps have extra low vibration and low magnetic field signature variants for sensitive electron microscope applications.

The compact design means the pumps fit together neatly in high product density applications. They are easy to configure and have an intelligent control interface accepting a 24 to 48Vdc input power supply voltage range and can be controlled using a simple parallel control or serial communications in both RS232 or RS485 formats.
