Copley Scientific Critical Flow Controller TPK/-R

Ensure all equipment is connected properly

Verify the BAC 2100/-R is powered on

Is the BAC 2100/-R flow meter calibrated?

Conventional Metered Dose Inhalers (MDIs) Testing

Set the air volume for DDU testing

Is the MDI Actuation Sensor properly clipped onto the MDI canister?

Select the operation trigger method

Test Set-up - Delivered Dose Uniformity (DDU) of DPIs

Enter the desired pressure drop for the inhaler (e.g. 4.0 kPa)

Replace the inhaler with a suitable flow meter (unless inline method used)

Check for critical (sonic) flow conditions (P3/P2 > 0.5)

Is the flow rate required to generate the pressure drop more than 100 L/min?

Automatically measure and report test set-up parameters

Test Set-up - Aerodynamic Particle Size Distribution (APSD) of DPIs

Connect a suitable flow meter to the inlet of the impactor and turn on the vacuum pump

Enter the flow rate required (e.g. 60 L/min)
