Filter Testing Interview: No Compromise on Accuracy in Filter Testing
All mover the industry, separation processes play an important role. But what use is the best filter setup, if the cartridge are defect? PROCESS talked with Dr. Jens Meyer, Product Manager, Integrity Testing & Air Filtration, Sartorius Stedim Biotech (SSB), about the company's new Sartocheck 4 Filter Integrity Testing system...
PROCESS: What are the advantages and main features of Sartocheck 4 Plus?
DR. JENS MEYER: One clear benefit is the short test time without compromising test accuracy. The design of the unit enables the user to set parameters in an intelligent manner, reducing test time by more than 80 per cent compared with standard settings. For example, the test time of a standard diffusion test can be reduced from 10 min- 1-2 min. by activating the automatic test time mode in Sartocheck 4 Plus.
I think the most important feature of Sartocheck 4 is its cleaning function. Sartocheck 4 Plus enables the internal pneumatic parts to be cleaned using NaOH of up to 1 M. A subsequent rinsing step with pure water, followed by drying, guarantees that the internal pneumatic components are thoroughly cleaned. This liquid-based cleaning function is really unique on the market and helps avoid potential cross-contamination when the unit is connected to anotherfilter housing.
A last example, I would like to mention is the barcode scanner. Barcode scanner cannot only enter the data in the system but also can be used for programming the Sartocheck 4 Plus. Once a complete list of test programs has been defined (up to 250) and the unit is set to start automatically, it will select the suitable test program(s) from the entire database as soon as the cartridge is scanned.
This enhances the safety and reliability, eliminating the risk of operator errors. In addition, Sartocheck 4 Plus considerably reduces the time it takes to program and start a test.
