Description

General description

The Isopore^™ membrane comprises polycarbonate film, with a smooth, glass-like surface that aids in clearer sample observation. This track-etched screen filter is recommended for sample analysis on the membrane surface. Isopore^™ membranes are useful in airborne contaminants analysis using electron microscopy.

Application

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

Isopore^™ Membrane Filter has been used in:

• the filtration of supernatant from isolated microplastics from riverine sediment dredge piles
• Dimethyldioctadecylammonium bromide (DODAB) vesicle preparation for biophysical studies
• filtering drinking water for microbes analysis

Features and Benefits

• Isopore^™ membranes display low background interference.
• Surface particle retention enabling simplified counting and analysis.
• Non-hygroscopic favors rapid drying and easy sample analysis.
• Translucent material; available in brown variety as well.

Caution

Possible reduction in flow rates may occur after autoclaving.
