Sterlitech Polycarbonate (PCTE) Membrane Filters

Sterlitech Polycarbonate Track Etch (PCTE) membranes are precision-manufactured from a thin, microporous polycarbonate film. These membranes feature uniform pore structure and low protein binding, making them ideal for use in blood assays, particle analysis, and general laboratory filtration where high flow rates and precise retention characteristics are critical.

Engineered for high-purity filtration, PCTE membranes support a wide range of applications including cytology, microbiological studies, and diagnostics. Their chemical resistance and compatibility with multiple sealing methods make them versatile for various device integration techniques such as ultrasonic sealing, heat sealing, RF bonding, and insert molding.
