Polycarbonate Track Etched Membrane Discs, 2.0um, 47mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215629

Featuring a thin, microporous polycarbonate track etched film with precisely defined cylindrical pores, this 47mm membrane disc delivers a 2.0um absolute pore size for accurate size separation. The polycarbonate base is naturally hydrophobic but is treated with polyvinylpyrrolidone (PVP) to render it hydrophilic, enabling reliable wetting and flow with aqueous samples. Its translucent, glass-like surface captures all particles larger than the pore size on a single plane, making the retained material easy to visualize under a microscope.

Key Polycarbonate Track Etched Membrane Characteristics

• Hydrophilic: PVP treatment converts the naturally hydrophobic polycarbonate film into a hydrophilic membrane for consistent aqueous flow.
• Absolute pore size: The 2.0um track etched pores are precise and uniform, capturing 100 percent of particles larger than the rated pore size on the surface.
• Smooth, flat surface: The thin, translucent structure retains particles in a single plane, easing microscopic and analytical visualization.
• Low protein binding: Minimizes sample loss and supports clean recovery of retained material.
• Superior strength and chemical staining resistance: Durable construction holds up to handling while resisting chemical staining for clearer analysis.

Key Construction Characteristics

• Material: Polycarbonate Track Etched (PCTE) film.
• Format: 47mm diameter membrane disc, white, non-gridded.
• Sterility: Supplied nonsterile.
• Pack: 100 discs per pack.

This membrane provides predictable flow and trusted particle retention across high-purity and general filtration tasks. The uniform, surface-capturing pore structure supports accurate particle analysis while preserving sample integrity. Its strength and low binding make it a dependable choice for repeatable laboratory results.

• General Filtration Provides reliable clarification of aqueous and high-purity samples with a uniform, absolutely rated 2.0um pore structure.
• Particle Analysis and Microscopy The smooth, flat surface captures particles in a single plane for easy microscopic and SEM visualization of retained material.
• Blood and Cellular Assays Suitable for removal of red blood cells from plasma and flow control of reagents through assays.
• Prefiltration Serves as a precise prefilter to protect downstream membranes from larger particulates.
• Microbial Surface Capture Retains organisms on the flat surface for direct counting and enumeration.
