PRODUCT OVERVIEW
Designed for low-binding, high-value fluid filtration
The PT69SPSTMS sterilizing-grade cartridge combines a double-layer hydrophilic polyethersulfone (PES) membrane with an all-polypropylene construction.
The dual-layer membrane design increases dirt-holding capacity and throughput while reducing the risk of premature clogging. It also delivers broad chemical compatibility, low extractables and exceptional flow rates at low pressure drops.
The low-binding nature of the PES membrane minimizes product loss through adsorption, making the cartridge especially well suited to high-value biologicals, vaccines and protein-containing solutions.
