Polycarbonate (PCTE) Membrane Discs, 1.0um, 293mm, Hydrophilic, Nonsterile, 20/Pk
GVS SKU: 1215145

Featuring a hydrophilic Polycarbonate Track Etched (PCTE) film with precisely defined 1.0um cylindrical pores, this 293mm membrane disc captures all particles larger than the pore size on a smooth, flat surface for even, single-plane particle distribution. The thin, translucent polycarbonate film is treated with a PVP wetting agent to render the naturally hydrophobic polycarbonate hydrophilic, supporting aqueous filtration and microscopic sample examination. Supplied nonsterile in a pack of 20 discs.

Key PCTE Membrane Characteristics

• Hydrophilic surface: treated with polyvinylpyrrolidone (PVP) so the polycarbonate film readily wets out with aqueous samples.
• Precise pore structure: a two-step track-etch process produces precisely controlled pore size and density for accurate size separation.
• Surface capture: particles larger than the pore size collect on a smooth, flat, single plane, simplifying optical and electron microscopy.
• Low protein binding: negligible adsorption and absorption of filtrate help preserve sample integrity.
• Visualization friendly: resists chemical staining to ease microscopic examination of captured material.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film.
• Format: 293mm membrane disc, plain (not gridded).
• Pore size: 1.0um nominal.
• Sterility: nonsterile.
• Pack: 20 discs per pack.

The track-etch structure delivers a narrow pore distribution and reproducible flow behavior across the membrane surface. Negligible filtrate adsorption and low protein binding help maintain sample integrity through filtration, while the flat capture surface keeps retained particles ready for downstream analysis.

• General Filtration Clarifies aqueous samples and removes particulates 1.0um and larger from a range of laboratory fluids.
• Microscopy Sample Prep Captures particles on a single flat plane for clean optical and electron microscope examination.
• Particle Analysis Provides precise, narrow pore distribution for accurate size separation and surface particle capture.
• Blood and Cell Studies Suited to blood assays and removal of cells from suspension thanks to low protein binding.
• Prefiltration Serves as a precise prefilter to protect downstream membranes from larger particulates.
• Environmental Sample Prep Collects suspended particles from water and other samples for subsequent enumeration or imaging.
