Kurt J. Lesker Company Pump Classifications Technical ...

A pump's ultimate pressure, often called its ultimate vacuum, is a value measured when the pump's design is finalized and an example built. In general terms, it is measured by blanking the pump's inlet with a pressure gauge, operating the pump for some time, recording the pressure achieved, and calling that the ultimate pressure.

Vacuum Pumps: The Widest Dynamic Range of Any Lab

Vacuum pumps have perhaps the widest dynamic range of any lab device, operating from just under atmospheric pressure, 760 Torr, to 10 -17 Torr—a difference of almost 10-20. Most lab vacuum applications operate at pressures of between 1.5 Torr and 150 Torr, with the 75- to 150-Torr range typically served by house vacuum.
