Featuring a thin, translucent polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, these 142mm membrane discs deliver consistent 1.0um filtration with a smooth, flat surface ideal for high-purity and general separations. All particles larger than the pore size are captured on the membrane surface, providing predictable flow control and clean recovery. The membrane is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate hydrophilic, and is supplied nonsterile in packs of 20.
Key Polycarbonate Track Etch Membrane Characteristics
- Hydrophilic surface: PVP treatment converts the naturally hydrophobic polycarbonate into a wettable, hydrophilic membrane for aqueous filtration.
- Precise cylindrical pores: A two-step track etch process controls pore size and density so all particles larger than 1.0um are captured on the surface.
- Smooth, translucent surface: A glass-like planar surface eases particle identification by optical and electron microscopy and resists chemical staining.
- Low protein binding and low extractables: Negligible adsorption and absorption maximize critical solution recovery and promote clean, consistent results.
- Superior strength: The film maintains pore size and density under load and will not stretch.
Key Construction Characteristics
- Material: Polycarbonate track etch (PCTE) film, plain (not gridded).
- Format: 142mm diameter membrane disc with a 1.0um pore size.
- Maximum use temperature: Rated for use up to 140 degrees C.
- Sterility and pack: Supplied nonsterile, 20 discs per pack.
These membranes deliver reproducible, high-purity separations while protecting sample integrity through low binding and negligible adsorption. The dimensionally stable polycarbonate film maintains pore geometry under pressure, supporting clean filtration and reliable downstream analysis.
