Bioreactor Filter

Our sterile filtration system is meticulously engineered to meet the rigorous demands of modern biopharmaceutical manufacturing processes, ensuring superior sterility assurance and regulatory compliance. Constructed using PTFE, PVDF, and polyether sulfone (PES) materials that are fully compliant with USP Class VI, this system guarantees zero leachables or adsorption, making it ideal for sensitive biological products such as vaccines and monoclonal antibodies.

Fully compliant with GMP, FDA 21 CFR Part 11, EU GMP Annex 1, and other international standards, our filters provide traceability throughout the filtration process, meeting stringent audit requirements. With a filtration accuracy of 0.22 μm (absolute rating), these filters achieve a Sterility Assurance Level (SAL) of 10⁻⁶, effectively removing all bacteria and fungi. The system supports in situ sterilization (SIP) at 121°C wet heat sterilization or gamma irradiation, ensuring performance stability post-sterilization.

Each filter comes with a unique batch number and QR code, enabling full traceability from raw material sourcing through production and testing. Comprehensive validation documentation, including IQ/OQ/PQ reports, material certifications, and microbial retention validation, helps clients achieve swift GMP certification. Certified by CE, ISO 13485, and FDA registration, the system is ready for deployment in global biopharmaceutical facilities, minimizing compliance risks.

Designed without dead spaces or volumes, the system prevents microbial growth, adhering to sterile pharmaceutical production standards. It is adaptable across multiple bioreactor types, including stirred-tank, wave-mixed, and single-use systems, supporting cell culture, fermentation, and viral vector production. Filter membranes are available in various pore sizes (0.1 μm, 0.22 μm, 0.45 μm), accommodating diverse microbial retention and particle filtration needs.

The system’s broad flow rate range (1-1000 L/min) supports scalability from small-scale research (10L) to large-scale commercial production (10,000L). It withstands wide pH ranges (1-14) and temperature ranges (-20℃ to 135℃), suitable for both acidic/alkaline media and high-temperature sterilization processes. Compatibility extends to gas and liquid filtration, including air, oxygen, carbon dioxide, nitrogen, media, feeds, and buffers.

With high flux rates exceeding traditional filters by over 30%, low protein adsorption (<0.5%), and excellent anti-fouling properties, the system ensures minimal energy consumption and extended lifespan. Designed for robustness, the housing uses 316L stainless steel or food-grade plastics, offering strong corrosion resistance and structural integrity under high pressures (≥0.6 MPa).

For ease of maintenance, disposable models eliminate the need for cleaning and sterilization, reducing labor costs and contamination risks, while reusable models feature easy disassembly for efficient cleaning and membrane replacement. Optional differential pressure alarms monitor filtration status, prompting timely filter changes to prevent failure. This filtration system stands as a reliable solution for maintaining purity and sterility in biopharmaceutical operations, from R&D to commercial scale.
