BPS filters are multipurpose products that excel in bioburden reduction, clarification and the prefiltration of aqueous fluids when sterilizing is not the goal. They consist of a single layer of Polyethersulfone (PES) membrane and deliver high flow and throughput across a wide pH range.

πŸ“ BPS Filter pore sizes range from 0.03 to 1.2 Β΅m, and the optional pre filter pore sizes range from 0.2 to 1.0 Β΅m
πŸ“‰ BPS filters have low binding characteristics which is necessary when filtering fluids with high proteins and preservatives.
πŸ›‘οΈ Installing the BPS Filter (single or dual layer) protects the final filter from premature fouling, and extends its useful life.

πŸ“° "Filter Integrity Testing Without Capital Expenditure"

For many filter users, it's crucial, if not essential, to have a method for testing your filters to ensure their proper functioning. This test can be conducted before filtration to verify that the process will operate as intended, or after filtration to check for any issues that may have arisen during processing. In some critical applications, it may be beneficial to perform both types of tests. The most prevalent method involves conducting a filter integrity test.
