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 distinct 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.

Application

• Chemotaxis
• Bioassays
• Cytology
• Air monitoring
• SEM analysis
• Sterility testing
• Microplastics analysis
• Microplastics analysis grade water

Isopore^™ Membrane Filter has been used in:

• water filtration for metagenomic studies
• the recovery of planktonic microorganisms
• air monitoring
• epifluorescent microscopy
• chemotaxis assays

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

Caution

Possible reduction in flow rates may occur after autoclaving.
