Ultra High Vacuum Pump

As the market leader in vacuum technology we can offer a complete range of vacuum pumps and gauges from atmosphere to ultra high vacuum.

Ultra high vacuum pump.

Seals and gaskets used between components in a uhv system must prevent even trace leakage. Ultrahigh vacuum conditions allow the usage of in situ monitoring such as reflection high energy electron diffraction rheed low energy electron diffraction leed and analytical instrumentation such as auger electron spectroscopy aes and x ray photoelectron spectroscopy xps to get information about crystallinity texture and composition. The pressure range of xhv is usually defined as 10 12mbar and lower while uhv is between 10 7and 10 12mbar and hv between 10 7and 10 3 mbar. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km so the gas is in free molecular flow and gas molecules will collide with the chamber walls many times before colliding with each other.

Units are compact so they fit on top of a workbench or table. What is the definition of high ultra and extreme high vacuum. Ultra high vacuum stp pumps the stp magnetically levitated turbomolecular pumps are the first choice for high up time hydrocarbon free pumping. Across international rv8 edwards rv8 dual stage high capacity vacuum pump with fittings 6 9 cfm 110 220v 50 60 hz 2 437 37 2 437.

Gamma vacuum pumps ultra high vacuum technologies edwards offers a range of ion pumps titanium sublimation pumps non evaporable getter pumps and accessories exclusively through gamma vacuum. The multi axis magnetic bearing system is used to suspend the rotor during operation ensuring there is no risk of contamination while minimizing vibration noise and maintenance requirements. Uhv conditions are created by pumping the gas out of a uhv chamber. Therefore nearly all such seals are all metal with knife edges on both sides cutting into a soft gasket typically copper.

Ultra high vacuum ligo s optical components quietly reside in a colossal vacuum chamber encompassing 10 000 cubic meters 353 000 cubic feet with an air pressure of 10 9 torr or one trillionth of an atmosphere. 37 2 690 00 2 690 00 get it as soon as tue sep 22. Ultra high vacuum is the vacuum regime characterised by pressures lower than about 100 nanopascal. Capture pumping technologies create high vacuum hv and ultra high vacuum uhv environments for a variety of applications ranging from portable mass spectrometers to large scale particle accelerators.

Electric ultra high vacuum pumps achieve vacuum levels up to 1 x 10 12 torr with these ultra high vacuum pumps. In order to achieve ultra high vacuum conditions special materials and pumping procedures are needed.
