Copley Scientific launches new Critical Flow Controller Model TPK-R™ for streamlined DPI testing

31 October 2013; Nottingham, UK: Copley Scientific has launched a new critical flow controller model, the TPK-R™, to improve the ergonomics of test set-up when using the Next Generation Impactor (NGI) for dry powder inhaler (DPI) testing. A mirror image of the Critical Flow Controller Model TPK™ , itself an industry standard, the TPK-R produces the stable, defined air flow profile required for successful aerodynamic particle size measurement with the NGI. For more information on the new model, please visit www.copleyscientific.com

Measuring the aerodynamic particle size distribution of DPIs is an essential in vitro test during product development and for QC. Cascade impaction is the required technique with the NGI normally being the impactor of choice. Testing must be carried out at a constant, controlled air flow rate to ensure that the NGI delivers precise, calibrated performance.

Copley Scientific’s TPK Critical Flow Controllers incorporate all the functionality required to ensure the application of a stable, precisely defined flow profile, in a single integrated system. The brand new model is identical to the TPK in all respects except for the inlet, outlet and user interfaces, which have all been reversed to connect more conveniently with the right-hand outlet of the NGI. Using the TPK-R therefore allows the more efficient use of laboratory bench space, without compromising the validity of existing test methods.
