Polycarbonate Track Etched Membrane Discs, 0.1um, 142mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1215304

Featuring a thin, translucent polycarbonate film with precisely defined cylindrical pores, this hydrophilic Polycarbonate Track Etched (PCTE) membrane disc delivers exact surface-capture filtration at a 0.1um pore size across a 142mm diameter. All particles larger than the pore size are captured on the smooth, flat membrane surface, making it well suited to high-purity general filtration and surface particle analysis. The membrane is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic and is supplied nonsterile in packs of 20.

Key Polycarbonate Track Etched (PCTE) Membrane Characteristics

• Absolute pore size and density that captures 100 percent of particles and cells larger than the pore size, providing precise size separation
• Hydrophilic surface achieved through PVP treatment for consistent wetting in aqueous applications
• Smooth, thin, translucent surface that eases microscopic visualization and resists chemical staining
• Low protein binding for clean recovery of filtered samples
• Superior mechanical strength that maintains pore size and density without stretching

Key Construction Characteristics

• Polycarbonate track-etched membrane formed by ion-beam exposure followed by chemical etching to create precise cylindrical pores
• 0.1um pore size on a 142mm diameter disc, white, not gridded
• Nonsterile, supplied 20 discs per pack

The controlled two-step track-etching process maintains tight pore size and density tolerances so each disc performs predictably across runs. The planar, glass-like surface supports reliable particle identification by optical or electron microscopy, while low protein binding helps preserve sample integrity during recovery.

• High-Purity General Filtration Captures particles larger than 0.1um on the membrane surface for clarification in applications where high purity is required.
• Microscopy and Particle Analysis The smooth, translucent, glass-like surface supports particle identification and surface sample viewing by optical or electron microscopy.
• Cellular-Based Filtration Assays Precise cylindrical pores provide flow control for reagents and capture of cells larger than the pore size.
• Blood and Plasma Sample Prep Surface-capture filtration supports removal of cells from samples for downstream analysis.
• Precise Size Separation Absolute pore size and density enable defined fractionation of particles by size.
• Microbiology and Sample Clarification Hydrophilic surface and low protein binding suit aqueous sample filtration with clean recovery.
