This miniature two stage pump features an alternative inlet connection position at the side of the pump so that overall installation height can be reduced to a minimum when required. The interstage version features an additional pumping port to provide a rough vacuum for auxiliary duties. This pump is widely used on mass spectrometers including the Agilent/HP 5971, 5972, 5973, 5975, and 5977.
