TefloGas Filter Cartridges

Hydrophobic PTFE Membrane · Sterilizing Grade

Cobetter TefloGas^® Filter Cartridge is made of inherently hydrophobic PTFE membrane and thick thermal-resistant polypropylene core. They are characterized with non-metallic ion release, dead-free corner and easy to clean when compared to those with a stainless steel core. As a result, they are highly recommended for the sterile filtration of gas, air in pharmaceutical, biological liquids and fermentation industries.

Features and Benefits

Inherently hydrophobic.
Exceptionally high flow rates with and low pressure drops.
Steam sterilizable up to 150 cycles at 121°C.
100% Integrity Tested by all methods including Water Intrusion Test.
Absolute rated filtrer.

Quality and Biological Safety

Integrity Testing
All cartridges are integrity tested by the aerosol challenge test methods with VALAIR DATA II. Diffusional Flow<16 ml/min at 0.8bar(11.6psi). Water intrusion<1.35ml/min. Values are for cartridges wetted with 60/40 IPA/Water.

Steam Sterilization
71-GPF cartridges can be repeatedly in situ steam sterilizal for up to 150 cycles at 121°C,30min at a maximum differential pressure of 0.5 bar

Validation
71-GPF cartridges have been fully validated as sterilizing grade
filter cartridges, for compressed air and gas applications. It passed the DOP test with DH VALAIR DATA II.
Food and Biological Safety
Extractables < 30mg per 10 inch
Endotoxins < 0.25EU/mL
Meets the requirements for food contact: European Regulation (EC) Number 1935/2004
