Palltronic® Flowstar IV Filter Integrity Test Instrument
•Brochure: Palltronic® Flowstar IV Filter Integrity Test Instrument
The Palltronic Flowstar IV integrity test instrument is a highly sensitive measurement instrument for gas pressure and flow. Highly sensitive pressure sensors are available from many sources, but highly accurate gas flow sensors for a measurement range of 0.01 to 1000 mL/min are not. However, such a range is required for an integrity test in pharmaceutical production.
The Palltronic Flowstar IV integrity test instrument utilizes a method that was developed by Pall for use in integrity test instruments and patented as "volume-dosed flow measurement technology". The current version of this flow meter consists of a valve block with three high precision pressure sensors, a pressure regulator, three defined volumes and a specific control algorithm.
The benefits of this technology are:
- Integrity test is much faster, as upstream volume does not have to be measured
- The flow measurement loop is directly calibrated
- The flow rate does not need to be calculated out of volume determination and pressure decay measurement
- The Forward Flow and Water Intrusion Tests are run at constant pressure over the complete test time
