Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, this Polycarbonate Track Etched (PCTE) membrane disc delivers accurate, surface-capture filtration at a 12.0um pore size in a 13mm diameter format. The membrane is treated with PVP (polyvinylpyrrolidone) wetting agent to render the naturally hydrophobic polycarbonate hydrophilic, and its smooth, flat surface captures all particles larger than the pore size directly on the surface for straightforward microscopic examination. Each pack contains 100 nonsterile, white, non-gridded discs.
Key Polycarbonate Track Etched (PCTE) Membrane Characteristics
- Hydrophilic surface: Treated with PVP wetting agent so the polycarbonate film readily wets out for aqueous filtration.
- Precise cylindrical pores: A controlled two-step track-etch process produces well-defined pores that capture 100 percent of particles larger than the pore size on the membrane surface.
- Smooth, glass-like surface: The planar surface makes the membrane well suited to particle identification and optical analysis by microscopy.
- Low protein binding and low extractables: Minimizes sample loss and helps keep filtrate clean for consistent results.
- Superior strength: The track-etched polycarbonate film maintains pore size and density and resists stretching under use.
Key Construction Characteristics
- Material: Polycarbonate Track Etched (PCTE) film.
- Diameter: 13mm disc format.
- Pore size: 12.0um.
- Color and grid: White, not gridded.
- Sterility and pack: Nonsterile, supplied 100 discs per pack.
This membrane provides reliable surface filtration and flow control for liquids moving through the membrane, with negligible absorption to support critical solution recovery. Its precise pore structure and clean, low-extractable construction help maintain sample integrity from filtration through downstream analysis.
