Hydrophilic Polytetrafluoroethylene Cartridge

YWF series cartridges filter media is a hydrophilic PTFE membrane, being able filter low-concentration polar solvent. They have universal chemical compatibility, applicable to sterilization of such solvents as alcohols, ketones, and esters. At present, they are widely applied in pharmacy, food, chemical industry, and electronics. YWF cartridges show excellent heat resistance, they can be repeatedly used in online steam sterilization or high-pressure disinfection. YWF cartridges also have high interception efficiency, high guarantee, and long service life.

Key Features

◇ Fusion welding; no object emission, low precipitation, long service life;

◇ Stable hydrophile, easy to get wet, hydrophilic performance will not decrease as time passes by or temperature changes;

◇ Single- or double-layer, solid structure; endurable to repeated online sterilization;

◇ Cartridge independently numbered, production batch traceable;
◇ Passing 100% integrity test; quality safe and reliable;

Typical Applications

◇ Filtering low-concentration polar solvents and sterilization;

◇ Sterilization of acids and alkalis and particle removal;

◇ Purification requirements in chemical industry, electronics, and microelectronics;

◇ Sterilization of antibiotic solutions;
