At the heart of every inhaler testing system is the Pump. The Pharmacopoeias are careful to point out that “a vacuum pump with excess capacity must be selected in order to draw air at the designated volumetric flow rate” through the system and in the case of Dry Powder Inhalers, to generate sonic flow.
Copley offers a choice of three pumps dependent on the set-up concerned and the capacity required.
Designed for optimal operation at low flow rates, the Low Capacity Pump Model LCP5 is ideal for MDIs and Nasal Sprays tested at 28.3 L/min. The flow rate can be adjusted between 0 and 133 L/min using the control valve on the front of the unit.
