Advancing metered-dose inhaler testing – Copley Scientific launches BAC™ 2100 Breath Actuation Controller

12 January 2017; Nottingham, UK: 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.

As an optional accessory to the BAC™ 2100, a new MDI Actuation Sensor has been made available; a discrete device that clips onto the MDI canister, it senses the manual actuation of the MDI and precisely triggers the BAC™ 2100 for subsequent time delay and/or flow volume control, simplifying testing for the user and enhancing reproducibility of testing.

Anna Sipitanou, Business Development Manager at Copley Scientific, comments:

“After the successful launch of our new TPK™ 2100 we identified the value of transferring much of the technology across to MDIs, where recent additions to the USP chapters relating to MDIs call for a range of parameters to be controlled and monitored, like for DPIs. This need led us to the creation of BAC™ 2100 which has been designed specifically for assisting analysts to perform MDI testing in a consistent and reproducible manner, but also eases the process of moving a drug application forward by satisfying regulators with robust data reporting functions. We can see the BAC™ 2100 becoming the new benchmark for MDI testing.”

In addition to the launch of the new BAC™ 2100, a new BAC™ 2100-R is being released in parallel. This is a modified version where the flow inlet and outlets are reversed to allow for different arrangements of the test equipment to be located on the laboratory bench.
