An ion-sublimation combination pump is the best choice for creating an ultra-high vacuum environment for certain applications. Agilent’s titanium sublimation module creates extra-high pumping speed for getterable gases, while the ion-pumping mechanisms handle non-getterable gases, such as argon and methane.   
   
The VacIon Plus combination pump is a VacIon Plus 150, 300, or 500 with an extra side- or bottom-mounted 8-inch ConFlat Flange port. The sublimation cryopanel containing a titanium filament source is mounted on the extra port.   
   
The Agilent VacIon Plus series of pumps permits the addition of a cryopanel either on the bottom or the side of the pump. This flexibility can be a significant when height restrictions are a concern.
