Copley Scientific Ltd's new Sample Preparation Unit (SPU) Series automates post-test rinsing of the induction ports and delivered dose sampling apparatus used in testing inhaled drugs. The SPU aids drug recovery from USP/Ph. Eur. induction ports and delivered dose sampling apparatus. Applicable for both metered dose and dry powder inhalers, it is available in two configurations, with either one or two rinsing positions.
The SPU is a cost-effective, labour-saving addition to Copley's extensive range of equipment for inhaled drug testing. A small footprint system it ensures complete and repeated wetting of the component's internal surfaces during rinsing, optimising the drug recovery process. Any combination of four different interchangeable fixtures can be selected, allowing the user to match rinsing capabilities with laboratory demands. While the SPU 1000 model has a single rinsing fixture position, the SPU 2000 model has two, allowing simultaneous rinsing of any two components.
Both units offer variable speed rotation in the range 20 60 rpm and have automatic reverse rotation. Rinsing can be controlled on the basis of time (in the range 0 8 hours) or number of turns (0 to 9999). The required rinsing parameters are simply selected once solvent has been dispensed into the component, the open ends have been capped, and the component is secured in the fixture.
