This allows the Sartorius system to automatically capture all important data directly coded on the respective filter cartridges as data matrix code, such as filter type, lot number and date of expiration. Immediately after the data of a filter cartridge have been scanned in, the integrity test system selects the right test programme from its database, which makes the process more user-friendly and efficient.  
The Sartocheck 4 plus system also features fast test sequences and automatic timing for intelligent acceleration of testing. There is also automatic detection of errors in the test equipment set-up, such as a disconnected filter housing. Additional units can be connected to the integrity test system, making it possible for users to run independent as well as parallel tests of up to five different filters. 
The patented cleaning function of the integrity test system enables reliable sanitisation of the internal pneumatic components, even after aggressive cleaning agents (up to 1 M NaOH) have been used. There is also the option of using external vent valves.
The Sartocheck 4 plus has been designed according to GAMP guidelines and complies with 21 CFR Part 11 Requirements. This unit offers a choice of electronic data transfer options, such as PDF files, network connectivity, Profibus, SD cards, and can be interfaced with the appropriate process control systems for automatic control of integrity testing.
