Thumbnail Filmstrip of Polycarbonate (PCTE) Membrane Disc Filters, 1.0um, 47mm, Hydrophilic, Nonsterile, 100/Pk Images
Featuring a thin, microporous polycarbonate film with precisely defined, cylindrical pores, this 47mm polycarbonate track-etched (PCTE) membrane disc delivers an absolute 1.0um pore rating for accurate size separation. Produced through a two-step manufacturing process with tight control over pore size and density, the membrane offers a smooth, translucent, glass-like surface that captures particles on a single plane for simplified microscopic and SEM examination. A polyvinylpyrrolidone (PVP) treatment renders the membrane hydrophilic, allowing it to process aqueous and alcoholic samples without prewetting. This 1.0um, 47mm membrane is supplied nonsterile, 100 per pack.
Key Polycarbonate (PCTE) Membrane Characteristics
- Hydrophilic: PVP surface treatment enables use in water and aqueous solutions without prewetting.
- Absolute pore rating: precisely cylindrical, narrowly distributed 1.0um pores capture particles on the surface for precise size separation.
- Low protein binding: among the lowest non-specific binding of any membrane type, ideal for blood and biological assays.
- Superior strength: the integral polycarbonate film provides a strong, thin, translucent structure.
- Resists chemical staining: the smooth, glass-like surface eases microscopic visualization and particle analysis.
Key Construction Characteristics
- Material: polycarbonate track-etched (PCTE) film.
- Format: 47mm membrane disc, plain (not gridded).
- Pore size: 1.0um.
- Sterility: nonsterile.
- Pack: 100 per pack.
The uniform, absolute-rated pore structure delivers predictable flow and trusted particle retention for reproducible results. With its smooth surface and low extractables, this PCTE membrane maintains sample integrity across general filtration and analytical applications.
