The MPS membrane is a hydrophilic polyethersulfone (PES) membrane with asymmetric pore structure which ensures high flow rate at minimal differential pressure and high thermal and chemical stability. The polyethersulfone membrane has very low binding ability to prevent the loss of product caused by adsorption of proteins and preservatives.
Main applications
- Fine and sterilizing filtration of solvents with high and low pH levels, protein containing solvents and blood preparations.
- Bioburden reducing filtration and sterilizing filtration of parenterals and pharmaceutical liquids, high viscosity media including ophthalmic solutions.
- Filtration of biological solutions containing high amount of colloid particles.
- Prefiltration and sterilizing filtration of aggressive media (acids, alkalis, solvents and photoresists).
- Microbiological control.
- SDI detection (filterability test).
Features and advantages
- High filtration rate.
- High thermal and chemical stability.
- Extremely low content of extractable substances.
- Withstand not less than 20 cycles of steam sterilization in autoclave at t = 121°C without any changes of mechanical, structural and filtration properties as well as gamma-radiation.
- Resistant to alkaline solutions, alcohols, chemicals and solvents.
