General description

The Isopore membrane is a polycarbonate, track-etched screen filter recommended analysis of airborne contaminants and other particles using optical or electron microscopy. It aids accurate size separation in samples due to precise pore diameter and consistent pore size. Isopore membrane filter may be useful in air monitoring, epifluorescent microscopy, and chemotaxis assays.

Application

Isopore membrane filter has been used for filtering:
  • fillet fish homogenate suspension for microplastics sampling
  • cyanobacterium Acaryochloris cells
  • titanium particles

Features and Benefits

  • Isopore membranes display low background interference.
  • Particle retention aids in easy counting and analysis.
  • Non-hygroscopic and reduced sample analysis time.
  • Translucent material.
  • Also available in a brown variety.

Caution

Possible reduction in flow rates may occur after autoclaving.
