Characteristics and features
Excellent high-tem resistance and extensive chemical compatibility.
All constituent materials comply with the biological test characteristics of USP Class VI 121 ℃ plastic products, and comply with the food contact materials listed in the relevant provisions of Chapter 21 of the United States Federal Regulations (CFR).
Excellent hydrophilicity, suitable for sterilization and filtration of strong acid and alkali liquid.
The sampling of filter element successfully passed the bacterial challenge test required by regulations, LRV≥7.Integrity can be maintained after repeated high-pressure disinfection.
Each filter element should pass the integrity test before leaving the factory. The limitations of integrity testing were correlated with the results of bacterial challenge experiments.
It is manufactured under ISO 9001 and ISO 14001 systems and Class 100 environment.
Production and usage are traceable.
Large air flow, low differential pressure and long service life.
