Thumbnail Filmstrip of Polycarbonate Track Etched Membrane Filter Discs, 0.2um, 90mm, Hydrophilic, Nonsterile, 30/Pk Images
Featuring a thin polycarbonate track etched (PCTE) film with precisely defined cylindrical pores, this 0.2um hydrophilic membrane disc delivers exact size separation across a smooth, flat 90mm filtration surface. The membrane is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, producing a translucent, low-background filter well suited to high-purity filtration and microscopic analysis. Each disc measures 90mm in diameter, is supplied nonsterile, and packs 30 per pack.
Key Polycarbonate Track Etched Membrane Characteristics
- Hydrophilic surface: PVP treatment provides reliable wetting for aqueous samples and consistent flow.
- Precise pore structure: Track etching forms uniform cylindrical 0.2um pores for accurate size separation.
- Low protein binding: Minimizes sample loss and nonspecific adsorption during filtration.
- Smooth, translucent surface: Resists chemical staining to ease microscopic visualization with optical or electron microscopes.
- Superior strength: The thin polycarbonate film maintains structural integrity under handling and filtration.
Key Construction Characteristics
- Membrane material: Polycarbonate Track Etch (PCTE), white and not gridded.
- Diameter: 90mm disc format.
- Pore size: 0.2um nominal rating.
- Sterility: Nonsterile.
- Pack: 30 discs per pack.
The defined pore geometry and high-purity construction deliver repeatable separation and clean backgrounds across analytical workflows. Low protein binding and stain resistance help preserve sample integrity and support clear downstream visualization. Each disc provides consistent, reliable filtration performance from one membrane to the next.
