The filter produced is compliant with the 2015 edition of the Chinese Pharmacopoeia. It features a membrane pore size of no more than 0.45µm and a diameter of 50mm. The following step-by-step instructions will guide you through the proper operation method, ensuring ease of use and safe handling.
1. Before use, immerse the filter membrane in sterile water for 6 to 8 hours to ensure it becomes fully moistened. This helps prevent damage during installation and ensures optimal filtration performance.
2. Loosen the round nut located at the bottom of the filter head, then lift the metal holder. Carefully remove the glass tube and place a rubber washer inside the filter bucket. Next, insert a stainless steel filter plate and position a tetrafluoroethylene film gasket on top. Place the microporous membrane, followed by the membrane gasket and silicone gasket. Then, reinsert the glass cylinder into the base, replace the metal holder, and tighten the round nut securely. Finally, cover the top cap to complete the assembly.
3. Unscrew the valves on the base, connect a rubber tube to the drain port, and wrap the tubing neatly. Cover the base with kraft paper to maintain cleanliness and prevent contamination.
4. Avoid over-tightening the round nuts at the bottom of each filter head. Keep them slightly loose to allow for better air circulation and easier handling. Wrap each filter head with kraft paper to protect it during storage or transportation.
5. After steam sterilization at 121°C for 15 minutes, place the filter head and base in a 37°C incubator to dry completely before use. This ensures that all components are fully sterilized and ready for immediate application.
Consumables such as glass cylinders, rubber gaskets, film gaskets, silicone gaskets, rubber stoppers, and microporous membranes should be purchased in advance to avoid delays during critical operations. Proper preparation and maintenance are essential to ensure the long-term efficiency and reliability of the filtration system.
