Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, this 25mm Polycarbonate Track Etched (PCTE) membrane disc delivers controlled 10um size separation across a 100-piece pack. The membrane is produced through a two-step track-etch process in which polycarbonate film is exposed to ion particles that create tracks, which are then chemically etched into precise, cylindrical pores, providing tight control over both pore size and density. Treated with polyvinylpyrrolidone (PVP) for hydrophilic wettability, it captures particles larger than the pore size directly on its smooth, flat surface.
Key Polycarbonate Track Etch Membrane Characteristics
- Hydrophilic surface: Treated with PVP wetting agent to wet readily with aqueous samples while the base polycarbonate is naturally hydrophobic.
- Precise, cylindrical pores: Track-etch manufacturing yields a defined pore size and narrow pore distribution for accurate size separation, capturing particles larger than the pore size on the surface.
- Smooth, glass-like surface: The thin, translucent, planar film is well suited to particle identification by optical or electron microscopy.
- Low protein binding and low extractables: Negligible absorption and adsorption promote clean results and maximize critical solution recovery.
- Resists chemical staining: Eases microscopic visualization of captured samples.
Key Construction Characteristics
- Material: Polycarbonate Track Etched (PCTE), 10um pore size.
