The Beckman Coulter Multisizer 4e is the gold standard in particle characterization, offering unmatched accuracy and flexibility. With a wide sizing range of 0.2 to 1600 μm, it enables high-resolution measurement across diverse sample types. Now enhanced with a 10 μm aperture, the system can accurately detect particles as small as 200 nm, including sub-cellular and microparticles—ideal for advanced research and quality control applications.
Engineered with an advanced noise reduction system, the Multisizer 4e ensures highly accurate measurements, especially when working with small apertures. Leveraging Beckman Coulter’s patented digital pulse processing (DPP) technology, it delivers ultra-high resolution and can detect as few as one particle per milliliter, independent of particle shape, color, or optical properties.
Using the Coulter Principle (electrical sensing zone method), this instrument delivers reliable, reproducible results for a wide array of particle types, making it a versatile solution for laboratories working with:
- Mammalian cells
- Bacteria
- Yeast
- Abrasives
- Toner particles
- Cell aggregates
- Spheroids
- Large protein aggregates
Versatility
- Aperture sizes from 10 µm – 2000 µm in diameter for current & future needs
- Multiple aperture options & data overlay capability for analyzing complex samples over wide particle size distribution
Sample Detection
- Analyze materials in aqueous or non-aqueous solvents
- Ideal for biological or non-biological samples
- Detect particles regardless of material type or optical properties
Rapid Particle Counting
- Typical sampling rates up to 10,000 counts per second
- Detect & count particles from 0.2 µm – 1600 µm in diameter
- Sample volumes as small as 5 mL
Data Management
- Digital pulse data can be stored & re-analyzed as needed
- CFR 21 Part 11 compliant software for audit control & security
- Variety of calibration beads & V-check validation controls
