Their capillary pore structure is uniform and precise, with a narrow pore size distribution to retain particles on their surface. Track-etched membranes are an excellent choice for accurate fractionation of particulates because of their precise pore size.

Track-etch technology offers the user distinct performance advantages when excellent surface capture and high sample visibility are required. Their main applications are particulate analysis, epifluorescence microscopy, fluid clarification, cytology, cell biology, bioassays, water microbiology and environmental analysis.

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.

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.

Hydrophobic PTFE Membrane Filters

The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.

Polyamide Membrane Filters

Polyamide membrane filters are hydrophilic and chemical resistant to alkaline solutions and organic solvents.

Polyethersulfone (PES) Membrane Filters

Polyethersulfone membrane filters are hydrophilic- have high flow rates- a low non-specific protein adsorption and are chemically resistant over a pH range of 1 – 14.<-p>

Regenerated Cellulose Membrane Filters

The regenerated cellulose membrane filters are made of regenerated cellulose reinforced with a cellulose nonwoven.
