VacIon Plus 300 Pump

The VacIon Plus 300 L/s pump provides high pumping speed in a moderate footprint and weight and is used in laboratories where ultrahigh and extreme high vacuum conditions are crucial.

This pump is available with three types of elements. Diode elements are for general-purpose UHV and XHV applications where the highest hydrogen pumping speed is critical and the system is seldom vented or prone to atmospheric leaks. StarCell elements handle a high amount of noble gases (better than noble diode) and hydrogen (comparable to the diode). StarCell also provides the highest speed and capacity for methane, argon, and helium. Noble diode elements are for general-purpose UHV and XHV where pumping of residual argon and other noble gases is required.
