Non-Evaporable Getter Pumps

NEG Pumps or Non-evaporable getter pumps, utilize high porosity sintered materials and pump through surfaces sorption of gas molecules. Often used in UHV and XHV applications because of their high pumping speed for light gases, in particular hydrogen, which is the main residual gas at such pressure levels.

Being able to achieve 10e-14 mbar range, they are extremely compact and can be installed in any direction. Making them perfect for installation in narrow and hard to reach places. One activated, the pump does not require power to operate making it highly energy efficient. Being vibration free makes it perfect for applications that are vibration sensitive such as electron microscopy and other surface analytical instrumentation. This is due to their passive nature making their interaction with magnetic fields negligible.
