PNC Filters: Positively Charged Nylon 6,6 Membrane

By Critical Process Filtration

Filtration efficiency in pharmaceutical and bioprocessing applications depends on removing contaminants without compromising flow or product integrity. Positively charged membrane technology offers a targeted solution by attracting and capturing negatively charged impurities such as endotoxins, viruses, and cellular debris.

This mechanism enhances overall contaminant reduction while supporting reliable sterile filtration performance across a range of aqueous and nonaqueous fluids. With multiple pore size options, operators can tailor filtration to specific process requirements, balancing retention and throughput. Validated bacterial retention, low extractables, and compatibility with standard sterilization methods further support consistent, compliant operation. Designed for scalability from laboratory to production environments, this approach provides flexibility for applications such as process water and high-purity water systems.

To protect sterility and lower contamination risk, teams must understand how charge-based filtration supports stronger control and consistent performance. Click to learn more.
