BRPES

Summary

Product Identification

The BRPES-Series High Purity Bio-Burden Reduction Grade Filter Polyethersulfone Cartridges are validated and 100% integrity tested. They provide bio-burden and small particle removal across a wide range of food & beverage, biological liquids, and intermediate bulk pharmaceutical fluids. These cartridges are constructed with a unique single-layer hydrophilic asymmetric polyethersulfone membrane, offering broad chemical compatibility, high flow-rates at low pressure drops, and low extractables. BRPES cartridges are suitable as either a final filtration stage or as an effective prefilter to a sterilizing stage. Manufactured in a clean-room environment for high standards of purity and cleanliness.
