Multisizer 4e Coulter Counter from Beckman Coulter Life Sciences
Beckman Coulter Life Science’s Multisizer 4e Coulter Counter is a multifaceted system for particle counting and characterization.
Using the Coulter principle, the system detects particles through electrical zone sensing, irrespective of the nature or the optical properties of the particle. Thanks to this feature, it is theperfect tool for the detection and counting of an extensive range of particles, for example:
Yeast
Mammalian cells
Large protein aggregates
Bacteria
Abrasives
Cell aggregates
Toner particles
Spheroids
Features
Versatility
The system features aperture sizes with a diameter ranging from 10 to 2000 µm to fulfill the existing and future demands.
The data overlay capability and multiple aperture options provided in the system enable the analysis of complex samples over wide particle size distribution.
Sample Detection
The system is best suited for non-biological or biological samples.
Materials in non-aqueous or aqueous solvents can be analyzed.
Particles can be detected irrespective of type or optical properties of the material.
Rapid Particle Counting
Particles with a diameter ranging from 0.2 to 1600 µm can be detected and counted
Typical sampling rates of up to 10,000 counts per second
Sample volumes as low as 5 mL
Data Management
Users can store and re-analyze digital pulse data as needed
Range of calibration beads and V-check validation controls offered
Software compliant with CFR 21 Part 11 provided for audit control and security
