Copley Scientific Launches BAC™ 2100 Breath Actuation Controller

Capitalising on the success of the Critical Flow Controller Model TPK™ 2100 for dry powder inhalers (DPIs), Copley Scientific has launched the BAC™ 2100, an advanced Breath Actuation Controller to help automate flow control when testing metered - dose inhalers (MDIs) for delivered dose uniformity and aerodynamic particle size distribution.

The new BAC™ 2100, which replaces its predecessor, the BAC™ 2000, provides flow control for a range of MDI applications, including a time delay feature for the actuation of MDIs when used with spacers and valved holding chambers (VHCs) according to new USP Chapter <1602>. It can also be used for flow volume control when testing regular MDIs according to USP Chapter <601> and for the automatic actuation of breath-actuated MDIs. Advanced features include a fully automated in situ cascade impactor leak testing function and extensive data reporting capabilities, with the choice of outputting data to a printer or computer. Test duration is calculated automatically from the required flow volume – typically 2 litres in the case of MDIs – based on the measured flow rate, derived from a connected flow meter. The menu system has further been enhanced to guide the user through the required steps to ensure consistency and error free completion of the test method.
