The Beckman Coulter 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

Fluid Compatibility: All aqueous and non-aqueous electrolyte solutions devised for use with aperture technology are suitable for use with the Multisizer 4e. Electrolytes should be compatible with glass, fluoropolymers, fluoroelastomers, and stainless steel.
