Polycarbonate Track Etch Membrane Disc Filters, 0.08um, 293mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1222096

Featuring a thin, microporous polycarbonate track-etched (PCTE) film with precisely defined, straight-through cylindrical pores, this hydrophilic membrane disc delivers accurate surface filtration with a sharp 0.08um size cutoff. The 293mm diameter disc presents a smooth, flat surface for even particle distribution in a single plane, and a polyvinylpyrrolidone (PVP) treatment renders the membrane hydrophilic for ready wetting in aqueous samples.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: PVP treatment promotes consistent wetting and uniform flow with aqueous solutions.
• Precise pore structure: Straight-through, cylindrical 0.08um pores provide a sharp, surface-based size cutoff for accurate separation.
• Low protein binding: Negligible adsorption and absorption preserve filtrate integrity and analyte recovery.
• Smooth, flat surface: Even particle capture in a single plane supports downstream microscopy and analysis.
• Chemical stain resistance: Resists chemical staining to ease microscopic visualization of captured particles.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE), hydrophilic.
• Format: 293mm diameter membrane disc.
• Sterility: Nonsterile.
• Pack: 20 discs per pack.

The track-etched screen structure captures particles at the surface, yielding more accurate cutoff than depth media and supporting reliable, repeatable separations. The thin yet durable polycarbonate film maintains sample integrity across general and high-purity filtration workflows.
