DIPTFE Membrane Pleated Filter Cartridge
- Commodity name： DIPTFE Membrane Pleated Filter Cartridge
Description
Product Introduction
DIPTFE series pleated polytetrafluoroethylene filter cartridges use imported hydrophilic modified polytetrafluoroethylene filter membranes as the filtration material. They possess broad chemical compatibility, resisting strong acids and alkalis. The modified hydrophilic properties allow for direct filtration of polar aqueous solutions. 100% integrity testing is performed before shipment to ensure absolute sterilization.
Performance Characteristics
● Excellent high-temperature resistance and broad chemical compatibility.
● Excellent hydrophilicity, suitable for sterilization filtration of strong acid and alkali liquids.
● High flow rate, low pressure drop, and long service life.
● Filter cartridge batch sampling has successfully passed the bacterial challenge test required by regulations, with an LRV >7, and maintains integrity after multiple autoclave sterilizations.
● Each filter cartridge undergoes integrity testing before leaving the factory. All integrity testing limits used have been verified and correlated with bacterial challenge test results.
● All constituent materials comply with the biological testing characteristics of USP Class 6 121°C plastic articles and meet the requirements for food contact materials listed in Chapter 21 of the US Federal Regulations (CFR).
● ISO 9001 and ISO 14001 systems.
● Traceable product production, testing records, and usage.
