PF-BEV
Polyethersulphone Double Layer Cartridge Filters
A range of microbially rated cartridge filters from Ultrafilter, featuring the latest developments in membrane technology, PF-BEV 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-BEV 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. Consequently, PF-BEV Serie cartridges provide a combination of features and benefit 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.Typical applications:
- Biopharmaceuticals
- Ophthalmic solutions
- Electronics and semiconductors
- Photoresists and developers
- Pure water supply system

PF-PES
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.Typical applications
- Biopharmaceuticals
- Ophthalmic solutions
- Electronics and semiconductors
- Photoresists and developers
- Pure water supply systems

PF-PP
Polypropylene Membrane Cartridge Filters
PF-PP Serie cartridges are manufactured using a polypropylene membrane of uniform thickness and high voids, with a homogeneous structure and controlled pore sizes. They are designed for the removal of submicron organic and inorganic particulate matter. The inherent structural stability of the membrane eliminates any risk of media migration and minimizes the release of particles. For solvent and aggressive chemical filtration applications, PF-PP Serie cartridges offer a wide range of chemical compatibility. They are suitable for the most demanding microfiltration applications and can be used for the filtration of aggressive chemical solutions, including acids, alkalis, solvents, and etchants. PF-PP Serie cartridges can also be used for a wide range of venting and gas filtration applications.Typical applications:
