New super-hydrophilic cartridge for sterile filtration

1 min read

Biofil™ R cartridges are an addition to the Biofil™ polyethersulphone Food Safety and USP Class IV approved range of filters, and feature a novel technology which renders the product super-hydrophilic.

Integrity testing of sterilising filter cartridges requires the membrane to be fully wetted; a cartridge that is insufficiently wetted will result in a false failure and require a retest or rejection of an intact filter.

This development extends the availability of Biofil™ cartridges to users that are currently unable to easily wet and integrity test filter cartridges due to low feed pressure and flow.

Mike Hughes, General Manager, said: “Many of our existing clients tell us that the new Biofil™ R cartridges are a welcome addition to our range of cartridges.”

“Conventional PES membrane filters offer significant process advantages with respect to flow and fouling resistance compared to others, but difficulties with wetting have hindered their easy adoption. The BiofilTM R overcomes this barrier”

“The launch of this range represents another step forward in our commitment to serve the scientific, medical, pharmaceutical, and R&D sectors.”

Manufactured based on a polyethersulphone membrane with an asymmetric pore structure, the cartridges have optimal filtration pack construction to maximise the available filtration area and to ensure an efficient flow.

Porvair will be exhibiting at Achema 2015 in Frankfurt 15–19 June 2015, Hall 5.1, Stand A16.
