General description

The Isopore™ membrane is a polycarbonate, track-etched screen filter recommended for all analyses in which the sample is viewed on the surface of the membrane. Isopore™ membrane offers distinct advantages for the analysis of airborne contaminants and other particles using optical or electron microscopy. The Isopore™ membrane is composed of polycarbonate film, which has a smooth, glass-like surface for clearer sample observation. The unique manufacturing process of the membrane ensures a precise pore diameter and a consistent pore size for accurate separation of samples by size. Matched-weight filters are not usually required because of low, constant tar and ash weights.
We are committed to bringing you Greener Alternative Products, which have been re-engineered to enable more sustainable research solutions. The inner & outer boxes containing the membrane discs are made from bio-circular material allocated using the ISCC mass balance approach. Click here for more information.

Application

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

Isopore™ Membrane Filter has been used in:
  • water filtration for metagenomic studies[1]
  • the recovery of planktonic microorganisms[2]
  • air monitoring
  • epifluorescent microscopy
  • chemotaxis assays

Features and Benefits

  • Membrane structure retains particles on the surface, simplifying counting and analysis
  • Isopore™ membranes do not stain, resulting in low background interference
  • Non-hygroscopic, allowing for rapid drying and reduced sample analysis time
  • Translucent material does not require clearing for transmitted light microscopy; also available in brown variety

Caution

Possible reduction in flow rates may occur after autoclaving.
