Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, this Polycarbonate Track Etch (PCTE) membrane disc delivers controlled surface capture at a 0.4um pore size across a 13mm diameter. All particles larger than the pore size are captured on the smooth, flat surface, making the membrane well suited to high-purity and general filtration as well as microscopy-based particle analysis. The membrane is treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate hydrophilic, supporting consistent wetting and reliable flow control.
Key Polycarbonate Track Etch Membrane Characteristics
- Hydrophilic: Treated with PVP wetting agent so the polycarbonate film wets readily for aqueous filtration.
- Precise pore structure: Track-etch process produces uniform, cylindrical 0.4um pores for predictable size separation and surface capture.
- Low protein binding: Minimizes sample loss and supports clean, reproducible results.
- Superior strength: Tensile strength exceeding 3000 psi (207 bar) maintains pore size and density without stretching.
- Resists chemical staining: Smooth surface eases microscopic visualization and reduces background interference.
Key Construction Characteristics
- Material: Polycarbonate Track Etch (PCTE) film.
- Format: 13mm diameter membrane disc, white, not gridded.
- Pore size: 0.4um.
- Sterility: Nonsterile.
- Pack: 100 per pack.
The track-etch manufacturing process holds pore size and density to tight tolerances, delivering dependable separations run after run. The smooth, glass-like surface keeps captured particles in a single plane for straightforward analysis while low protein binding protects sample integrity.
