Validation

PTM filters are validated using test procedures that comply with ASTM F 838-15(ae1) protocols for the determination of bacterial retention in filters used for liquid filtration. The challenge level is a minimum of 10⁷ organisms per cm² of filter media. CPF filters have > 7-log removal when challenged with the organisms (0.10µm and 0.22µm meets the FDA definition of sterilizing grade filters).

0.10µm: Brevundimonas diminuta
0.22µm: Brevundimonas diminuta
0.45µm: Serratia marcescens

Validation Guides available upon request.

Quality Assurance

PTM filters are 100% integrity tested. CPF filters are developed and manufactured under an ISO 9001:2015 certified Quality Management System and designed to be used in cGMP-compliant processes.
