PALL Palltronic Flowstar IV FFS04R
**This unit has been tested to specifications. Has broken right and left corners (Does not affect functionality) See photos for further details.
The Forward Flow Test is designed to test the integrity of hydrophilic and hydrophobic membrane filters. The test is based on measuring the gas flow across a completely wetted membrane at a defined test pressure on the upstream side. When the downstream side of the membrane is at atmospheric pressure a diffusion flow of gas is established due to the pressure differential. Larger pores and defects will be dewetted at the given test pressure causing a higher gas flow across the membrane. The measured flow is compared to the flow limit dependent on membrane type and filter area. If the filter exceeds the flow limits established by the membrane validation it is considered that the filter may be defective. under 21 CFR compliance that includes IQ/OQ.It is a device that performs automatic diagnosis, is light, compact, with a touch screen and built-in printer that allows:
Test filters in a reliable and repeatable way
Faster integrity testing
That the Diffusive Flow and Intrusion tests are carried out at a constant pressure
Electronic data management and remote control
This instrument provides the ability to perform either a Forward Flow Test, Bubble Point Test, combined Forward Flow and Bubble Point Test, Water Intrusion Test or Leak Test. The filter can be tested in place or off-line and its performance capacity remains unaffected by the test when
suitable protocols are followed. The instrument provides direct flow measurement of the filter under test. This measurement is independent of upstream volume over a wide range. Extensive internal Self Test features and use of high precision components virtually eliminate the possibility of significant measurement errors. The instrument is connected upstream of the filter under test. The measurements are, therefore, non-invasive of the downstream side of the filter and risk of contamination is eliminated. This is particularly important in installations where the filter has been sterilized before integrity testing.
The test instrument is a small and lightweight portable unit, which has been specifically designed for ease of use and accuracy of measurement. Data input is carried out using a touch screen that also displays other essential information. The instrument measures flow and pressure in real time and displays them graphically on the touch screen. An automatic control of the test system enables reduced test times to be achieved under stable test conditions.
Test times are automatically extended when unstable conditions are present. An integral printer provides a permanent record of the test parameters and results. In addition, up to 10,000 test results can be stored electronically in the instruments memory. The test instrument is dustproof and splash proof to a rating of IP54, providing protection against severe laboratory and production conditions. The venting system includes an External Vent Valve to prevent test liquid from migrating into the instrument on completion of the filter integrity test
