Polypropylene Membrane Cartridge Filters ChemifilTM cartridges are manufactured using a polypropylene membrane of uniform thickness and high voids, with a homogeneous structure and controlled pore sizes. Designed for the removal of sub-micron organic and inorganic particulate matter, the inherent structural stability of the membrane eliminates any risk of media migration and minimises the release of particles. For solvent and aggressive chemical filtration applications, ChemifilTM cartridges offer a wide range of chemical compatibility. Suitable for the most demanding microfiltration applications, the cartridges can be used for the filtration of aggressive chemical solutions including acids, alkalis, solvents and etchants. ChemifilTM cartridges can also be used for a wide range of sterile venting and gas filtration applications. Applications ChemifilTM polypropylene membrane cartridges meet the demanding filtration requirements of pharmaceutical, semiconductor and fine chemical manufacturers. They can be used for the fine filtration of aggressive chemical solutions including acids, alkalis, solvents and etchants. They are also suitable for a wide range of sterile venting and gas filtration applications, including the filtration of wet gases. • Fine chemicals and solvents The removal of submicronic particles from processing chemicals and solvents. • Photoresists and developers The microfiltration of photoresists and developer solvents, susceptible to contamination and precipitation during manufacture, storage and processing. • Pure water supply systems For use in de-mineralised and de-ionised water systems, for the supply of ultra-pure water, for example in the semiconductor industry. • Sterile process gases The supply of sterile gas for critical applications in the pharmaceutical, biotechnology, food and beverage markets. • Sterile vents The safe sterile venting of processing vessels in pharmaceutical, fermentation, and food and beverage processes. “Quality for Less” World Class Filtration Solutions

Polypropylene Membrane Cartridge Filters • ChemifilTM cartridges The all polypropylene cartridge construction makes it an ideal choice for the filtration of aggressive chemicals. • Controlled manufacturing environment ChemifilTM cartridges are manufactured in an ISO Cleanroom environment by fully gowned staff, minimising the risk of contamination. • Guaranteed microbial ratings ChemifilTM cartridges are validated for bacterial removal according to HIMA guidelines and ASTM F838-05, with a log reduction value >7.

Filter membrane: Membrane support: Irrigation mesh (support): Drainage layer: Inner core: Outer support: Minimum total extractables. Please refer to the ChemifilTM Validation Guide. Fusion bonding Integrity Testing Each ChemifilTM module of every cartridge is individually integrity tested using the Diffusive Flow Test, which correlates to the HIMA and ASTM F838-05 bacterial challenge tests. Non-destructive integrity tests, such as Diffusive Flow, Water Intrusion, Pressure Hold and Bubble Point, can be performed by customers. Procedural details are available from Porvair.
