Critical Flow and Breath Actuation Control

Copley’s Critical Flow Control TPK range and Breath Actuation Control BAC range are designed based on the requirements set out by both the European and the United States Pharmacopoeia for testing MDIs, DPIs, Nebulisers, ADIs and Nasal Products.

BAC 2100 - Breath Actuation Controller

Providing and documenting all critical parameters measured in the delivered dose uniformity testing (DDU) and aerodynamic particle size distribution (APSD) of metered-dose inhalers (MDIs), our Breath Actuation Controller Model BAC 2100, features an electronically-operated timer-controlled two-way solenoid valve. Available with inlet/outlet reversed (BAC 2100-R), the BAC 2100 series features the same flow meter, temperature and relative humidity connections and printing capabilities as found on the TPK 2100/-R.

  • Ideal for DDU/APSD measurement of both conventional and breath-actuated/MDIs

  • Automatic calculation of test duration from volume and flow rate

  • Fully automated in situ impactor leak testing function with pass/fail

  • USB interface for data output and remote actuation

BAC 2100/-R Features:

  • Conforms to specifications - both Ph.Eur. Chapter 2.9.18 and USP Chapter <601>
  • Integrated timer for control of solenoid valve
  • 2-way/2-port solenoid valve
