Hydrophilic filters posses an affinity for water and can be wetted with almost any liquid. Sterlitech carries a wide variety of hydrophilic membranes, including:

• Silver Metal
• Polyethersulfone (PES)
• Glass Fiber
• Polycarbonate Track Etch (PCTE)
• Polyester (PETE)
• Mixed Cellulose Esters (MCE)
• Nylon
• Cellulose Acetate

 

Hydrophobic filters lack an affinity for water and are best suited for venting applications. Example of hydrophobic filters are Sterlitech polypropylene membranes and Sterlitech PTFE (Teflon®), either laminated or unlaminated.
