Polycarbonate Track Etch Membrane Filters, 3.0um, 90mm, Hydrophilic, Nonsterile, 30/Pk
GVS SKU: 1222074

Featuring a thin, translucent polycarbonate track etch film with precisely defined cylindrical pores, this hydrophilic PCTE membrane delivers absolute 3.0um particle separation across a 90mm disc format. The PVP-treated surface wets readily with aqueous samples, while the smooth, flat structure captures all particles larger than the pore size directly on the membrane surface for clean, single-plane sample presentation. Supplied nonsterile, white, and not gridded, in packs of 30.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic surface: treated with polyvinylpyrrolidone (PVP) so the membrane wets readily for aqueous filtration.
• Absolute pore size: precise, cylindrical 3.0um pores provide controlled, predictable size separation.
• Surface capture: a thin, translucent film with a smooth, flat surface retains particles larger than the pore size directly on top of the membrane.
• Low protein binding: minimizes sample loss and supports accurate downstream analysis.
• Microscopy friendly: resists chemical staining to ease optical and SEM visualization of captured particles.

Key Construction Characteristics

• Material: polycarbonate track etch (PCTE) film.
• Diameter: 90mm disc.
• Sterility: nonsterile.
• Color and surface: white, not gridded.
• Pack: 30 membranes per pack.

The track etch structure provides consistent pore geometry and narrow pore distribution, delivering reproducible flow and reliable particle retention from disc to disc. Low non-specific binding and a contaminant-resistant surface help preserve sample integrity through clarification, prefiltration, and microscopic examination.

• General Filtration Clarifies and prefilters aqueous samples through an absolute 3.0um pore structure that captures larger particulates on the membrane surface.
• Particulate Removal and Prefiltration Removes coarse particles to protect and extend the life of finer downstream membranes.
• Surface Microscopy and SEM Sample Prep Captures particles on a smooth, flat plane and resists chemical staining for clear optical and electron microscope examination.
• Blood and Cellular Assays Suited to flow control and separation steps such as removal of larger cells, supported by low protein binding.
• Environmental Sample Preparation Provides defined-pore filtration of water and environmental samples for downstream particle analysis.
• Assay Reagent Flow Control Uses precise pore geometry to regulate the flow of reagents through assay systems.
