Multisizer 4e Coulter Cell Analyzer

Item#: Multisizer-4e

The Multisizer 4e COULTER COUNTER is a highly versatile particle counting and characterization system. It uses the Coulter principle to detect particles via electrical zone sensing, regardless of the particle’s nature or optical properties. This makes it an ideal tool for detecting and counting a wide variety of particles, such as:

  • Mammalian cells
  • Bacteria
  • Yeast
  • Abrasives
  • Toner particles
  • Cell aggregates
  • Spheroids
  • Large protein aggregates
