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

Isopore Membrane Filter has been used in:
  • air monitoring
  • epifluorescent microscopy
  • chemotaxis assays
  • 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

Packaging

100 filters

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.
