Description

General description

The Isopore^™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore^™ membrane offers many advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore^™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Matched-weight filters are not usually required because of low, constant tar and ash weights.

We are committed to bringing you Greener Alternative Products, which have been re-engineered to enable more sustainable research solutions. The inner & outer boxes containing the membrane discs are made from bio-circular material allocated using the ISCC mass balance approach. Click here for more information.

Application

• Absorbable organic halides (AOX)
• Particle monitoring
• Air monitoring
• Microplastics analysis
• Microplastics analysis grade water

Isopore^™ membrane filter has been used:

• for culturing organotypic brain slices[1]
• organotypic vibrosections[2]
• as a working electrode for the synthesis of Helical nanomotors.[3]

Features and Benefits

• Membrane structure retains particles on the surface, simplifying counting and analysis
• Isopore^™ membranes do not stain, resulting in low background interference
• Non-hygroscopic, allowing for rapid drying and reduced sample analysis time
• Translucent material does not require clearing for transmitted light microscopy; also available in brown variety
