Sartocheck® 4 plus Bag tester –
Fully automatic post installation pre-use testing of bags

The Sartocheck® 4 plus Bag tester is the result of a clear market request for testing single use bags and bioreactors, post installation pre-use and post-use. It is based on the same market leading software and hardware platform as the Sartocheck® 4 plus Filter tester and assures full communication compatibility between the both. As bags require lower test pressures and therefore also higher pressure accuracies than membrane filters, the pressure range has been reduced for an overall optimization of pressure accuracy and pressure drop measurement accuracy. The Sartocheck® 4 plus Bag tester provides the same combination of benefits as the Sartocheck® 4 plus Filter tester:

Testing of STR Cultibag

The Sartocheck® 4 plus Bag tester is the ideal tool for eliminating the risk of filling a defective single use bioreactor with high valuable cell cultures. The STR Cultibag is tested pre-use after installation into the STR holder. A unique patented fleece avoids direct contact between the plastic film of the bag and the smooth stainless steel surface of the holder. Any kind of potential masking effect is therefore eliminated and environmental heat transfer is reduced giving unrivalled test accuracy.
