VacIon Plus 200 Pump

The VacIon Plus 200 L/s pump delivers faster pumpdown (peak pumping speed: 10–8 mbar) due to an optimized magnetic field and is ideal where UHV and XHV conditions are crucial. The pump undergoes a vacuum firing process to minimize hydrogen outgassing.

Available with three types of elements. Diode elements are for general-purpose UHV and XHV applications where highest hydrogen pumping speed is critical, and the system is seldom vented or prone to leaks. StarCell elements handle more noble gases than noble diode and more hydrogen than diode, with 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.
