Featuring a thin, microporous polycarbonate track-etched (PCTE) film with precisely defined cylindrical pores, these 13mm hydrophilic membrane discs deliver controlled, absolute surface filtration at a 0.1um pore size. The polycarbonate base is produced through a two-step process in which the film is exposed to ion particles that create tracks, then chemically etched to open straight-through, uniform pores. Treatment with polyvinylpyrrolidone (PVP) renders the naturally hydrophobic polycarbonate hydrophilic for aqueous wetting. Each disc is supplied nonsterile, 100 per pack.
Key Polycarbonate Track Etched (PCTE) Membrane Characteristics
- Hydrophilic surface: PVP wetting treatment allows the membrane to wet readily for aqueous filtration.
- Absolute pore structure: Precisely defined, cylindrical pores capture particles larger than the pore size on the membrane surface for accurate size separation.
- Smooth, translucent surface: The thin, flat, glass-like surface supports microscopic particle identification and optical analysis.
- Low protein binding: Minimizes sample loss and supports consistent results.
- Superior strength: Resists stretching to maintain pore size and density under use, and resists chemical staining to ease microscopic visualization.
