General description

The Isopore membrane is a polycarbonate that allows sample visualization on membrane surface using optical or electron microscopy. Due to precise pore diameter and consistent pore size, it allows size-based sample separation with accuracy. It may be useful in chemotaxis assay, air monitoring, and epifluorescent microscopy.

Application

  • Chemotaxis
  • Bioassays
  • Cytology
  • Air monitoring
  • Microplastics analysis

Isopore membrane filter has been used to:
  • filter microplastics associated with microbes from seawater samples
  • wrap and encapsulate tumor for implantation in mice to mimic anti-angiogenic (AA) therapy
  • filter out phytoplankton and large-sized particles
  • hold mammalian cell lines for ultraviolet (UV) irradiation studies

Features and Benefits

  • Isopore membranes have low background interference.
  • Particle retention on the membrane surface favorable for counting and analysis.
  • Non-hygroscopic and translucent material.
  • Rapid sample drying and analysis time.
  • Also available in a brown variety.

Caution

Possible reduction in flow rates may occur after autoclaving.
