Featuring a thin, microporous polycarbonate track-etched (PCTE) film with precisely defined cylindrical pores, this 5.0um, 47mm membrane disc captures all particles larger than its pore size on a smooth, flat surface in a single plane. The polycarbonate base film is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polymer hydrophilic, supporting aqueous filtration, blood assays, and high-purity general filtration. Each translucent disc delivers narrow pore distribution and low non-specific binding, and is supplied nonsterile in a pack of 100.
Key Polycarbonate Track Etch Membrane Characteristics
- Hydrophilic surface: treated with PVP to wet readily for aqueous sample filtration despite the polymer's natural hydrophobicity.
- Precise cylindrical pores: a two-stage track-etch process gives tight control over pore size and density, capturing 100 percent of particles larger than the 5.0um rating on the surface.
- Smooth, translucent film: the flat surface distributes captured particles in a single plane and resists chemical staining for easy microscopic visualization.
- Low protein binding: exhibits negligible adsorption and absorption of filtrate for high-purity work.
- Thermally stable: withstands a maximum operating temperature of 140 degrees C and is autoclavable.
Key Construction Characteristics
- Material: polycarbonate track-etched (PCTE) film, white, non-gridded.
- Format: 47mm diameter membrane disc with a nominal thickness of 5 to 20um.
- Sterility: nonsterile.
- Pack: 100 discs per pack.
The precisely controlled pore geometry delivers consistent, repeatable surface capture for accurate particle sizing and analysis. Negligible leachables and low trace element levels help preserve sample integrity across high-purity filtration and microscopy workflows.
