Polycarbonate Track-Etched Membrane Disc Filters, 8.0um, 47mm, Nonsterile, 100/Pk
GVS SKU: 1215637

Featuring a thin, microporous polycarbonate track-etched (PCTE) film with precisely defined, cylindrical pores, these 47mm membrane discs deliver an 8.0um pore size for precise surface separation and high-purity filtration. Because polycarbonate is naturally hydrophobic, the membrane is treated with a wetting agent (PVP) to render it hydrophilic, supporting consistent wetting and reliable flow. The smooth, flat, translucent surface captures all particles larger than the pore size on top of the membrane, making it well suited to viewing and recovering retained samples.

Key Polycarbonate Track-Etched Membrane Characteristics

• Hydrophilic surface: PVP wetting-agent treatment promotes uniform wetting for aqueous samples.
• Precise, cylindrical pores: the track-and-etch process yields tightly controlled pore size and density for predictable size separation.
• Surface capture: all particles larger than the pore size are retained on the smooth, flat surface, ideal for optical and electron microscopy.
• Low protein binding: minimizes sample loss and resists chemical staining to ease microscopic visualization.
• High purity: negligible adsorption and absorption of filtrate with low trace element levels.

Key Construction Characteristics

• Membrane material: polycarbonate track-etched (PCTE).
• Format: 47mm membrane discs, white, not gridded.
• Sterility: nonsterile, supplied 100 per pack.
• Membrane thickness: 0.005 to 0.02mm (5 to 20um).
• Maximum use temperature: 140 degrees C.

The translucent, low-tare film provides repeatable flow control and clean separation across general filtration tasks. Surface capture keeps retained particles accessible for downstream observation, supporting sample integrity from collection through analysis.

• Particulate Removal The 8.0um pore size separates and retains coarse particles and cells larger than 8 microns from liquid samples.
• Cytology and Microscopy Smooth, flat surface capture allows direct observation of retained samples by optical or electron microscopy.
• Blood and Cell Studies Hydrophilic, low-protein-binding film supports blood assays and removal of larger cellular components from suspensions.
• General Filtration High-purity polycarbonate film suits general-purpose clarification where precise surface retention is needed.
• Prefiltration Coarse 8.0um rating protects downstream finer membranes from heavier particulate loads.
• Air Sampling and Aerosol Studies Defined pore geometry and low tare weight aid gravimetric and particle-capture sampling work.
