Polycarbonate Track Etched Syringe Filters, 12um, 25mm, Nonsterile, 100/Pk
GVS SKU: 1215984

Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, this 12 um, 25 mm polycarbonate track etched (PCTE) membrane disc captures all particles larger than its pore size directly on a smooth, flat surface. The film is produced through a two-step track-etch process in which ion particles create tracks that are then chemically etched into precise, cylindrical pores, giving tight control over pore size and density. Although polycarbonate is naturally hydrophobic, this membrane is treated with a polyvinylpyrrolidone (PVP) wetting agent to render it hydrophilic. It is supplied white, not gridded, nonsterile, in packs of 100.

Key Polycarbonate Track Etched Membrane Characteristics

Hydrophilic surface: Treated with a PVP wetting agent so aqueous samples wet the membrane readily.
Precise surface capture: Absolute pore size and controlled density capture 100 percent of particles and cells larger than the pore size on the membrane surface.
Smooth, translucent film: The glass-like planar surface supports particle identification by optical or electron microscopy.
Low protein binding: Negligible absorption and adsorption maximize critical solution recovery and promote consistent results.
Superior strength: High tensile strength maintains pore size and density without stretching during handling.

This membrane delivers uniform, single-plane particle distribution that supports reliable microscopic analysis and reproducible separations. Its low extractables and negligible adsorption maintain sample integrity, while the controlled pore geometry provides predictable flow and precise size separation. The result is consistent performance across general filtration, blood studies, and high-purity applications.
