Featuring a thin, microporous polycarbonate film with precisely defined cylindrical pores, these Polycarbonate Track Etch (PCTE) membrane discs deliver accurate surface separation at a 0.08um pore size in a 25mm diameter format. Polyvinylpyrrolidone (PVP) treatment renders the naturally hydrophobic polycarbonate hydrophilic, allowing the membrane to process aqueous and alcoholic samples without pre-wetting. Supplied nonsterile in a pack of 100, the smooth, translucent surface eases microscopic examination of retained particles.
Key Polycarbonate Track Etch Membrane Characteristics
- Hydrophilic surface: PVP-treated polycarbonate film wets readily for direct use with aqueous and alcoholic solutions.
- Precise cylindrical pores: Track-etch manufacturing produces uniform, straight-through pores with a narrow size distribution for accurate particle separation.
- Surface retention: Particles larger than the rated pore size are captured on the smooth, flat surface rather than within the depth of the film.
- Low protein binding: Minimal non-specific binding helps preserve sample integrity and recovery.
- Translucent, glass-like surface: Resists chemical staining and supports clear microscopic visualization of collected particulates.
Key Construction Characteristics
- Material: Single-layer polycarbonate track-etched film.
- Diameter: 25mm membrane disc.
- Color: White, not gridded.
- Sterility: Nonsterile.
- Pack: 100 discs per pack.
These membranes maintain consistent pore geometry and predictable flow behavior across the disc surface, supporting repeatable separation results. The low-binding, high-purity film helps protect sample integrity throughout filtration and downstream analysis.
