TPK - Critical Flow Controller

The Critical Flow Controller TPK is designed to control the test conditions needed when analysing Dry Powder Inhalers. The factors that affect these test conditions are:

  • The resistance to flow posed by the inhaler under test

  • The appropriate flow rate, Q, required to generate a 4 kPa pressure drop over the inhaler

  • The duration of inspiration required to give the specified test volume

  • The stability of the flow rate in terms of critical (sonic) flow

Product Features

  • Conforms to specifications - both Ph.Eur. Chapter 2.9.18 and USP Chapter <601>
  • Differential pressure meter for measuring pressure drop, P1 (Range: 0 to 100 kPa, Resolution: 0.1 kPa)
  • Flow control valve to adjust flow rate
  • Timer-controlled solenoid valve to adjust duration of flow (Range: 0 to 999.9 seconds, Resolution: 0.1 seconds)
  • Absolute pressure meter for confirming sonic flow, P2 and P3 (Range: 0 to 100 kPa, Resolution 0.1 kPa)
  • Membrane keypad control
  • LED display of differential and absolute pressure values
  • LCD back-lit display of set and elapsed actuation times
  • 2-way/2-port solenoid valve
  • Electronic timer for control of solenoid valve
  • Conforms to specifications - both Ph.Eur. Chapter 2.9.18 and USP Chapter <601>
