TSP22
The Titanium Sublimation Pump is a true UHV pump. It is used to supplement the pumping action of other UHV pumps, (normally Ion Pumps) as it can be more effective at pumping certain gases. The main advantages of this type of pump is, it is a simple, low cost solution, that gives you high pumping speeds

Description
The type TSP22 sublimation pump cartridge replaces all previous sublimation pump cartridges (type STI, ST2A and ST3), which are now obsolete. This design incorporates three 2.0mm diameter TiMo alloy hairpin style filaments. It is available with a standard insertion depth of 203mm (8″); non-standard depths from 120mm up to 400mm can be supplied to special order. The cartridge is manufactured principally from high quality stainless steel with alumina insulated feedthroughs, mounted on an 70mm OD flange. The conductors have a generous cross section to carry the current required by the three 2.0mm diameter hairpin filaments, and terminate in replaceable alumina insulation bushes and filament clamps.
