Filtration Membranes, Polycarbonate Track Etched (PCTE) Hydrophillic Black Membranes for Epifluorescence
Overview
GVS manufactures these Polycarbonate Track Etched (PCTE) Hydrophillic Black Membranes under Class 100K conditions through a two-step proprietary manufacturing process. The unique process allows for increased control over pore size and density to insure the physical properties of each membrane to precisely fit an application.
The PCTE Hydrophillic Black Membranes are thin, translucent and microporous polycarbonate films with a smooth and flat surface for even distribution and ease of identifying particles with a microscope. Unlike ordinary filter membranes the thin PCTE membranes do not trap particles in tortuous pore pathways. The black dye makes the membrane suitable for use in staining applications. The filters are gray in color but look black under reflected light, the ideal background for fluorescence microscopy.
The PCTE Membrane is hydrophilic due to PVP (polyvinylpyrillidone) treatment. Ask Rose Scientific about PVP-free hydrophobic PCTE membranes also available, as are a wide range of pore sizes.
Membranes are available in sheets and rolls as well as disks of other diameters.
Features
Smooth, thin and glass-like flat surface
Microorganisms are retained on one plane allowing for easy microscope access
Very precise pore size
Autoclavable
Biologically inert
Thermally stable, chemical resistant and superior strength that maintains pore size and density
Lack of staining, negligible autofluorescence and non-specific absorption insures low backgrounds
Ideal for epifluorescence microscopy
