Polyethersulphone Membrane Cartridge Filters
A range of microbially rated cartridge filters from Ultrafilter GmbH, featuring the latest developments in membrane technology, PF-PES Serie cartridges are based on a naturally hydrophilic polyethersulphone (PES) membrane with a mirrored asymmetric pore structure. When combined with quality all-polypropylene cartridge components and high-integrity manufacturing techniques common to all Ultrafilter cartridge filters, the polyethersulphone membrane provides a high-strength, long-life cartridge of consistently precise microbial retention.
PF-PES Serie 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 PF-PES Serie cartridges are also very suited to critical particle control down to 0.04-micron ratings. PF-PES Serie cartridges offer high flux rates and low differential pressures, a feature common to polyethersulphone membranes.
PF-PES Serie cartridges benefit from the low non-specific protein binding characteristics of polyethersulphone membranes. They are also highly resistant to integrity failure caused by steam sterilization and have excellent chemical compatibility characteristics. Furthermore, since they will not hydrolyze, PF-PES Serie cartridges are ideal for use in ultra-pure water supply systems (180 МΩ.cm).
As a consequence, PF-PES Serie 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.
