General description

The Isopore membrane is composed of a polycarbonate film, with a smooth, glass-like surface. This enables a clearer sample observation in optical or electron microscopy. It is useful in the analysis of airborne contaminants. Also, the Isopore membrane has a precise pore diameter and a consistent pore size. It may find applications in epifluorescent microscopy and chemotaxis assays.

Application

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

Isopore Membrane Filter has been used:
  • for the separation of respirable particles from sanded composites[1]
  • to filter particulate organic matter (POM) from seawater[2]
  • to concentrate the prokaryotic biomass from ocean water sample[3]

Features and Benefits

  • Particle retention on the surface for easy counting and analysis.
  • Isopore membranes display low background interference.
  • Rapid drying and minimal sample analysis time.
  • Translucent material.
  • Also available in a brown variety.

Caution

Possible reduction in flow rates may occur after autoclaving.
