Polycarbonate Track Etch Membrane Filter Discs, 1.0um, 19mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1227203

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, these hydrophilic membrane discs deliver a 1.0um pore size in a 19mm diameter format and ship 100 per pack. Because polycarbonate is naturally hydrophobic, the membrane is treated with a polyvinylpyrrolidone (PVP) wetting agent to render it hydrophilic, allowing it to process aqueous and alcoholic samples without pre-wetting. The track-etched structure captures all particles larger than the pore size on its smooth, flat surface, making it well suited to high-purity and general filtration.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic: Treated with a PVP wetting agent so the membrane wets out in water and aqueous solutions without pre-wetting.
• Precise pore geometry: Cylindrical, narrowly distributed pores formed by a two-step track-etch process provide exact surface particle capture.
• Smooth, glass-like surface: The thin, translucent planar film captures particles on the surface, making it ideal for particle identification by optical or electron microscopy.
• Low binding and low extractables: Negligible adsorption and absorption of filtrate help preserve sample integrity.
• Withstands elevated temperatures: Rated to a maximum operating temperature of 140 degrees C (284 degrees F) and autoclavable.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film.
• Format: 19mm diameter membrane disc, 1.0um pore size.
• Sterility: Nonsterile.
• Pack: 100 discs per pack.

The track-etch manufacturing process maintains tight control over pore size and density for consistent, reliable separations from disc to disc. Surface capture of all particles larger than the pore size supports accurate microscopic analysis while preserving sample integrity. These characteristics make the membrane a dependable choice for high-purity and general laboratory filtration.

• Microscopy and Particle Analysis The smooth, flat surface captures particles in a single plane, making them easy to view and identify with optical or electron microscopes.
• Blood and Cellular Assays Precise surface capture supports blood studies and cellular-based filtration assays such as removal of red blood cells from plasma.
• High-Purity Filtration Low extractables and negligible filtrate adsorption make the membrane suitable for high-purity sample preparation.
• General Laboratory Filtration The 1.0um hydrophilic membrane provides flow control and reliable particle removal for routine aqueous and alcoholic samples.
• Flow Control of Reagents Precisely defined cylindrical pores meter the passage of liquids and reagents through assay workflows.
• Prefiltration and Sample Clarification Surface capture of larger particulates protects downstream membranes and clarifies samples prior to analysis.
