Bioprocessing of cell cultures, serum and plasma

Increase process efficiency and ensure product quality by installing prefilters and bioburden control filters in key process steps. Prevent bacterial contamination in cell culture and fermentation tanks. Provide consistent fluid quality to protect vital downstream sterilizing and viral clearance filters.

Pharmaceutical formulation and filling

Protect product quality and patient safety with filters that are strategically placed in upstream and downstream processes. These highly configurable filters remove particles and bacteria from raw ingredients and intermediates before reaching final filters to ensure a sterile product.

Making the Transition to Critical Process Filtration.

Quality Assurance and Standards

Critical Process Filtration filters are designed for use in cGMP compliant processes. Our state-of-the-art manufacturing facility and quality-management system both meet ISO 9001:2015 standards. Each operation from assembly and test to cleaning, drying, and packaging is done in appropriately rated clean rooms, and each filter is assigned a lot code to ensure the traceability of manufacturing data and materials. A sophisticated MRP system collects and processes real-time data from manufacturing centers and inspection points.

USP Biosafety and FDA Compliance

The materials used to construct pharmaceutical-grade filters are non-toxic and meet the requirements for the MEM Elution Cytotoxicity Test and the requirements for Biological Reactivity Tests in the current version of the United States Pharmacopeia (USP) for Class VI - 121 °C Plastics. Critical Process Filtration filters comply with Title 21 CFR sections 210.3 (b)(6) and 211.72, for non-fiber-releasing filters. The levels of bacterial endotoxins in aqueous extracts from pharmaceutical-grade filters are below current USP limits as specified for water for injection.
