Multisizer 4e Coulter Counter

Reference: BEC-B23005

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,...
- Detection of particles from 200 nm to 1600 µm
- Accurate determination of sample cell number, size, and concentration
- Uses the Coulter Principle Technology (Electrical Sensing Zone)
- Detects and analyzes each particle individually without using optical methods
- Analysis of a single cell per unit of time
- Real time detection of changes in the average cell size
- Detection of individual particles that deviate significantly from the average sample particle size (determination of cell aggregates)
- Detects and cleans up blockage of the aperture tube
- Easy SOP creation
- Automated aperture calibration and verification
- Automated filtration efficiency monitoring

Includes 100 µm aperture tube, 200 mL glass sample beaker, stirrer and software
