Polycarbonate Track Etch Membrane Filters, 5.0um, 25 x 80mm, Hydrophilic, Nonsterile, 50/Pk
GVS SKU: 1221331

Featuring a thin, translucent polycarbonate track etch (PCTE) film with precisely defined, cylindrical pores, these 5.0um hydrophilic membrane sheets deliver controlled, surface-based particle capture across a 25 x 80mm format. The polycarbonate film is treated with polyvinylpyrrolidone (PVP), a wetting agent that renders the naturally hydrophobic polycarbonate hydrophilic so the membrane readily processes aqueous samples. Supplied nonsterile in a pack of 50, this membrane combines a smooth, glass-like surface with reliable pore uniformity for demanding analytical work.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: PVP treatment renders the inherently hydrophobic polycarbonate film hydrophilic for spontaneous wetting in aqueous solutions.
• Precise cylindrical pores: A two-step track-etch process produces uniform, precisely defined 5.0um pores for predictable flow and surface capture.
• Surface retention: All particles larger than the pore size are captured on the membrane surface rather than within the structure.
• Smooth, glass-like surface: The planar, translucent film supports particle identification and microscopic analysis.
• Low extractables and low protein binding: Clean construction promotes consistent, contaminant-free results.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) film, PVP-treated for hydrophilicity.
• Format: 25 x 80mm membrane sheet.
• Pore size: 5.0um.
• Sterility: Nonsterile.
• Pack: 50 per pack.

This PCTE membrane provides consistent pore uniformity and predictable flow, supporting dependable particle retention and sample integrity. Its low non-specific binding and smooth, translucent surface make it well suited to high-purity filtration and microscopy-based analysis. Each sheet delivers the controlled, surface-capture performance expected of track-etched media.

• High-Purity Filtration The precisely defined 5.0um pores and low extractables support clean, high-purity general filtration of aqueous samples.
• Microscopy Sample Preparation The smooth, translucent, glass-like surface captures particles larger than 5.0um on the surface for straightforward optical or electron microscopy.
• Particle Analysis Surface retention of larger particles makes the membrane suitable for collecting and identifying particulates by size.
• Cell-Based Filtration Assays Uniform cylindrical pores and a biocompatible film support cellular filtration and capture applications.
• Prefiltration The 5.0um rating protects finer downstream membranes by removing larger particulates from loaded samples.
