Adopting composite film packaging technology, with good breathability and antibacterial performance;

Adopting ultrasonic welding technology ensures airtightness and pressure resistance performance;

The pump tube is made of composite materials imported from Germany, which have high elasticity, long-lasting tension, wear resistance and compression resistance, and can ensure the smooth completion of maximum inspection capacity filtration;

100% pass the airtight performance test;

Adopting composite film packaging technology, with good breathability and antibacterial performance;

Adopting advanced ethylene oxide sterilization, SAL≤10-6， Compliant with the gas sterilization method requirements of the 2015 edition of the Chinese Pharmacopoeia;

Aseptic independent packaging, the packaging bag uses imported medical dialysis paper to maintain the sterility of the product for a long time, and can quickly resolve ethylene oxide, reduce ethylene oxide residue, and avoid the risk of false negatives;

Through microbial interception, microbial growth promotion (sensitivity), and sterility testing, ensure the authenticity and reliability of sterility test results;

Filter membrane: bubble point method, bacterial retention rate test;

Aseptic testing: 14 day cultivation period, consistent with the requirements of the European and American Pharmacopoeia.
