Features and benefits
• Ultra-Mem PF-PES cartridges
Careful media selection means that Ultra-Mem PF-PES cartridges are available to suit a wide range of process critical and general purpose applications.
• Guaranteed microbial ratings
Ultra-Mem PF-PES cartridges are validated for bacterial removal according to HIMA guidelines and ASTM F838-05, with a log reduction value >7. They are therefore suitable for applications requiring sterilising grade filtration.
• Low protein binding
Ultra-Mem PF-PES cartridges have excellent low protein binding characteristics, typically 10 times lower than nylon, 2 times lower than polysulphone and similar to PVDF.
• Will not hydrolyse
Compared with other membranes such as nylon, the polyethersulphone membrane used in Ultra-Mem PF-PES cartridges is extremely resistant to hydrolysis. Capable of exposure in excess of 2 years, they are ideal for hot deionised water applications.
• Excellent chemical compatibility
Resistant to many process chemicals, Ultra-Mem PF-PES cartridges are suitable for use in a wide range of process applications.
• Cartridge integrity and low TOC levels
Each Ultra-Mem PF-PES module of every cartridge is individually integrity tested. Each complete filter cartridge is flushed with pure water which is inspected daily for pyrogens using the standard LAL test. When required, they can be pulse flushed with 18MΩ.cm pyrogen-free ultra-clean water.
• Suitable for steam sterilising
Ultra-Mem PF-PES cartridges incorporating a stainless steel support ring can be subjected to steam sterilisation at 125°C (257°F) without loss of integrity.
• Full traceability
All Ultra-Mem PF-PES cartridges are individually and batch identified with a unique serial number. Each Ultra-Mem PF-PES cartridge is supplied with a Certificate of Quality and an operating instruction leaflet.
• Controlled manufacturing environment
Ultra-Mem PF-PES cartridges are manufactured in an ISO Cleanroom environment by fully gowned staff, minimising the risk of contamination.
