Cellulose Nitrate (Mixed Cellulose Ester) Membrane Filters
The cellulose nitrate (CN) or also called mixed cellulose ester (MCE) membrane filters are composed of cellulose nitrate and a small content of cellulose acetate. They are recommended for a broad range of applications like the filtration of aqueous solutions or for sample preparation.

Cellulose Acetate Membrane Filters
The hydrophilic cellulose acetate membrane filters combine high flow rates, good chemical resistance (pH 4-8) and thermal stability with very low adsorption characteristics. They are excellently suited for use in pressure filtration devices.

Polycarbonate Track-Etched Membrane Filters
These hydrophilic polycarbonate track-etched filters are manufactured from high quality polycarbonate film using track-etch technology. They have a sharply defined pore size of 0.2µm with a pore density of 5.0E+08cm². Pack of 100 white 47mm discs that have a high chemical resistance and good thermal stability for accurate fractionation of particulates. Smooth, flat surface for good visibility.

• Sharply defined pore sizes for accurate separation and retention of particles
• Smooth and translucent surface for excellent visibility of the retained particles
• Capture of the particles on the surface of the filter for precise quantification and reading under light microscopes or for SEM
• Filter diameter of 47mm
• Pack of 100 polycarbonate (PC) track-etched filters
