Miniature Ion Pump

Agilent Miniature VacIon pumps, often called appendage ion pumps, are offered in a diode or noble diode configuration and provide a pumping speed of 0.4 L/s. These small ion pumps are lightweight, emit a very low magnetic field, and have a maximum baking temperature of 400 °C.

Since the invention of the ion pump by Agilent (Varian) in the late 1950s, Agilent mini pumps have set the pace in the industrial field in a wide range of applications such as defense, space, telecommunications, research, and medical devices. They are often used to maintain electron tubes for their operational lifetime at high or ultrahigh vacuum pressure.
