Installed Bag Test - Sartorius Sartocheck 4 plus Operating Instructions Manual

7.14 Installed bag Test

Fig. 7-30 | Test parameters for installed bag test
This test sequence is designed for leak testing of 3 dimensional bags (e.g. STR
Cultibags) being installed in the appropriate STR holder equipped with fleeces.
The test sequence is based on the change in pressure within the bag system including
connected tubes and vent filters.
The pressure drop measured in the process can be used as a direct measure of the
bag set-up leak tightness and absence of flaws or similar defects, provided that the
upstream volume of the system is constant.
Enter parameters for the plate holder test
Test pressure: from 3–50 mbar
Stabilization time: 1-1080 minutes.
Test time: 1-1080 minutes
Max. pressure drop: 1-programmed test pressure
Filling time: 1-1080 minutes
Please verify the test parameters for the bag being tested. Applying too high a test
pressure may jeopardize the integrity of the bag.
Since the viscosity of remaining liquid may influence the leak rate of an eventual
flaw, please do not mix up pre-use test values with specifically validated post-use
values.
This test can also be used for testing vessels as long as they resist the applied
pressure.
