Polycarbonate Track Etch Membrane Discs, 0.08um, 142mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1222095

Featuring a thin, microporous polycarbonate track etch (PCTE) film with precisely defined cylindrical pores, this 142mm membrane disc delivers absolute size separation at a 0.08um pore size. Though polycarbonate is naturally hydrophobic, the membrane is treated with a wetting agent (PVP) to render it hydrophilic, making it well suited to high-purity and general filtration where precise particle capture is required. The smooth, translucent surface captures all particles larger than the pore size in a single plane.

Key Polycarbonate Track Etch (PCTE) Membrane Characteristics

• Hydrophilic: Treated with polyvinylpyrrolidone (PVP) wetting agent for ready wettability with aqueous samples.
• Absolute pore size and density: Precise, cylindrical pores capture 100 percent of particles larger than the rated pore size on the membrane surface.
• Smooth, glass-like surface: The thin, translucent planar surface makes the membrane ideal for particle identification and observation by optical or electron microscopy.
• Superior strength: High tensile strength maintains pore size and density and resists stretching during filtration.
• Low protein binding and low extractables: Negligible absorption and adsorption maximizes recovery of critical solutions and promotes clean, consistent results.

Key Construction Characteristics

• Membrane material: Polycarbonate Track Etch (PCTE), hydrophilic.
• Format: 142mm diameter membrane disc, plain (not gridded).
• Maximum use temperature: 140 degrees C (284 degrees F).
• Sterility: Nonsterile.
• Packaging: 20 membrane discs per pack.

The track etch process provides increased control over pore size and density so the physical properties of each membrane precisely fit specifications. This consistency maintains reliable flow control and dependable particle retention, while the low-extractable, low-binding film preserves sample integrity from filtration through downstream analysis.
