Polycarbonate Track Etch Membrane Discs, 0.8um, 25mm, Nonsterile, 100/Pk
GVS SKU: 1215619

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, these 0.8um, 25mm membrane discs deliver controlled surface capture for high-purity and general filtration. The film is produced through a two-step track etch process in which polycarbonate is exposed to ion particles that create tracks, then chemically etched to form uniform, cylindrical pores. The result is a thin, translucent membrane with a smooth, flat surface that captures all particles larger than the pore size directly on the membrane face. These discs are supplied nonsterile in packs of 100.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic surface: Treated with polyvinylpyrrolidone (PVP) to render the naturally hydrophobic polycarbonate hydrophilic for processing aqueous and alcoholic samples.
• Absolute pore rating: Precisely cylindrical, narrowly distributed pores provide accurate size separation and capture particles larger than the pore size on the surface.
• Low protein binding: Minimizes sample loss and supports consistent, clean results.
• Smooth, glass-like surface: Thin, translucent planar structure eases particle identification and microscopic analysis.
• Superior strength: The integral polycarbonate film maintains pore size and density and resists stretching during handling.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE), hydrophilic.
• Format: 25mm membrane disc, plain (not gridded).
• Pore size: 0.8um.
• Sterility: Nonsterile.
• Pack: 100 per pack.

These membranes deliver predictable flow and trusted particle retention across high-purity and general filtration workflows. Their low extractable, low protein-binding surface helps preserve sample integrity and supports reproducible analytical results. The clean, translucent film makes them well suited to applications that require subsequent microscopic visualization.

• General Filtration Captures particles larger than 0.8um on a smooth surface for routine clarification and high-purity sample preparation.
• Microscopy Sample Prep The thin, translucent, glass-like surface supports clear particle identification by optical or electron microscopy.
• Cellular and Blood Assays Low protein binding and a defined pore structure suit blood assays and cell-based filtration work.
• Reagent Flow Control Precisely cylindrical pores provide controlled flow of reagents through assay formats.
• Particulate Prefiltration Surface capture of larger particulates protects downstream membranes and instrumentation.
• High-Purity Filtration Low extractable levels help maintain sample cleanliness in purity-sensitive workflows.
