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.
