Polycarbonate Track Etch Membrane Disc Filters, 0.1um, 90mm, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1215150

Featuring a thin, microporous polycarbonate track-etched (PCTE) film with precisely defined cylindrical pores, these 0.1 um hydrophilic membrane discs provide absolute particle retention across a 90mm diameter format. The membrane is produced through a two-step manufacturing process in which polycarbonate film is exposed to ion particles that create tracks, which are then chemically etched into uniform, cylindrical pores. A polyvinylpyrrolidone (PVP) treatment renders the naturally hydrophobic polycarbonate hydrophilic, supporting efficient processing of aqueous and alcoholic samples.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: PVP-treated polycarbonate wets readily for consistent flow of aqueous and alcoholic samples.
• Absolute pore rating: Precisely cylindrical, narrowly distributed 0.1 um pores capture 100 percent of particles larger than the pore size on a single plane.
• Low protein binding: Minimal non-specific binding and low extractables promote clean, consistent results.
• Smooth, translucent structure: The thin, glass-like surface eases particle identification by optical and electron microscopy and resists chemical staining.
• Superior strength: The integral polycarbonate film maintains pore size and density without stretching.

Key Construction Characteristics

• Material: Polycarbonate track-etched (PCTE) film treated with PVP.
• Diameter: 90mm disc, not gridded.
• Color: White, translucent.
• Sterility: Nonsterile.
• Pack: 30 discs per pack.

These membranes deliver predictable, reproducible filtration backed by uniform pore geometry and a low-binding surface that protects sample integrity. The thin, planar structure captures particles for direct microscopic analysis without dissolving the filter or introducing background interference. Each disc maintains its physical properties to fit specifications reliably across general filtration and high-purity applications.

• Sterile and High-Purity Filtration The 0.1 um absolute pore rating supports microbial and small-particle retention in high-purity aqueous filtration workflows.
• Microscopy and Particle Analysis The smooth, translucent surface captures particles on a single plane for optical and electron microscopy without staining interference.
• Epifluorescence and Cell Counting Uniform cylindrical pores and low autofluorescence support fluorescent detection and enumeration of microorganisms.
• Blood and Cellular Assays Low protein binding and biocompatible polycarbonate suit blood assays and cellular-based filtration studies.
• General Laboratory Filtration Hydrophilic PVP treatment enables consistent flow of aqueous and alcoholic samples for routine clarification.
• Microbiology Sample Preparation Absolute retention of particles larger than 0.1 um aids capture of microorganisms for downstream testing.
