The Sartocheck 4 plus bag tester is designed for pre-use testing of single-use bioreactors after installation.
The pre-test device is based upon a proven pressure decay measurement method and the company claims it offers enhanced security and assurance.
Sartocheck 4 systems are designed for cell cultivation and single-use BIOSTAT Cultibag STR bioreactors, with operation volumes of 50 & 200 litres, can now be tested by this latest system.
The bag tester is capable of performing a pre-use test across an entire bioreactor, including the tubing and has the means to detect any leaks that may have been caused by operator handling errors upon installation.
Additionally, its fleece system acts as a porous spacer, which prevents direct contact between the bag and the surface of the holder which reduces heat transfer eliminates the effects of masking of any pinholes.
Sartorius has stated that later during 2013 the technology within the pre-test kit will be extended to allow testing of 500 & 1,000 litre systems.
