Polyethersulphone Membrane Cartridge Filters A range of microbially rated cartridge filters from Porvair Filtration Group, featuring the latest developments in membrane technology, BiofilTM II cartridges are based on a naturally hydrophilic polyethersulphone membrane with a mirrored asymmetric pore structure. When combined with quality all-polypropylene cartridge components and high integrity manufacturing techniques common to all Porvair cartridge filters, the polyethersulphone membrane provides a high strength, long life cartridge of consistently precise particle retention across a wide range of particle sizes. BiofilTM II cartridges exploit the narrow pore size distribution and high void volume of the media to provide a choice of cartridges capable of meeting the requirements of most applications. Careful media selection ensures that BiofilTM II cartridges are also very suited to critical particle control down to 0.04 micron ratings. BiofilTM II cartridges offer high flux rates and low differential pressures, a feature common to polyethersulphone membranes. BiofilTM II cartridges benefit from the low non-specific protein binding characteristics of polyethersulphone membranes. They are also highly resistant to integrity failure caused by steam sterilisation and have excellent chemical compatibility characteristics. Furthermore, since they will not hydrolyse, BiofilTM II cartridges are ideal for use in ultra pure water supply systems (18MΩ.cm). As a consequence Biofil II cartridges provide a combination of features and benefits not hitherto available from cartridges based on PVDF, nylon, mixed esters of cellulose or polysulphone membranes. They are suitable for applications ranging from sterile filtration, bioburden reduction and the clarification of a wide range of process liquids and end products. TM Applications BiofilTM II cartridges are suitable for the sub-micronic filtration of a wide range of process liquids, in applications where the characteristics of a naturally hydrophilic membrane are required. Typical applications include: • iopharmaceuticals B For the sub-micronic filtration of ingredients, intermediates, make-up waters and final products, including sterilisation, clarification and bioburden reduction. • Electronics and semiconductors For the sub-micronic filtration of process water and chemicals, including solvents, developers and photoresists. Applications typically include central water plant treatment and critical ‘wet bench’ point of use filtration. • Fine chemicals For the clarification and sterilisation of a wide range of process chemicals. • everages B For the clarification and sterilisation of various beverages, including the removal of yeast and spoilage organisms. Low colour removal is an additional advantage. • Pure water supply For use in de-mineralised and de-ionised water treatment systems, as either a resin trap sterilisation filter, or for bioburden reduction. • Opthalmic solutions Shelf life assured through the non-removal of preservatives. “Quality for Less” World Class Filtration Solutions

Please refer to the BiofilTM II Validation Guide. Integrity Testing Each BiofilTM II 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 Pressure Hold, Diffusive Flow and Bubble Point, can be performed by customers. Procedural details are available from Porvair. Clean...

Additional Information Material Conformity and Validation Suitable for use in Porvair filter housings and as direct replacements for existing cartridges, BiofilTM II cartridges can be supplied with end fittings to suit most hardware installations without modification. They are available in single or multiple module units of 5, 10, 20, 30 and 40 inches, and in a choice of six microbial ratings: 0.04, 0.10, 0.20, 0.45, 0.65 and 1.2 micron. BiofilTM II Junior versions are also available. Each cartridge is supplied with all necessary seals or O-rings to ensure chemical compatibility. The...
