Vacuum-Pump-for-Inhaler-Testing-The requirements of the various pharmacopoeia for flow control clearly define the need for high quality vacuum systems. Westech in conjunction with Erweka GmbH, Germany, supply enclosed rotary vane vacuum pumps to perfom this function.

High-Flow-Rate-Pump-for-Inhaler-Testing-The high resistance of some inhaler devices will not allow the standard pump (210lpm with control valve) to operate at the flow rates required by the Pharamcopoeia.
The High Flowrate Pump will overcome this although for high resistance devices at the highest required flowrates (>/= 100lpm) two such pumps may need to used in series.
