rightMORE INFORMATION

  • The Multisizer 4e particle sizer and counter is the most accurate and flexible particle characterization device available, boasting an unparalleled sizing range of 0.2 - 1600 μm. The new 10 μm Aperture allows users to study sub-cellular and micro-particles as small as 200 nm, while the advanced noise reduction system for small apertures improves measurement accuracy.

    Generated data are processed using patented digital pulse processing technology and can be saved and later re-analyzed. This technology provides ultra high resolution and accuracy unattainable through any other technologies: detection of 1 particle in 1 ml of a sample with the optimal instrument configuration. Analysis results are not dependent on particle shape, structure, or optical properties.

    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

  • Linearity Linearity for 2% - 60% of aperture diameter: ± 1% for diameter, ± 3% for volume
    Aperture Diameter Range 10 µm to to 2000 µm to
    Digital Pulse Processor Proprietary high-speed digitization of the signal
    Volumetric Mode Continuously selectable from 50 µL-2,000 µL
    Volumetric Pump Accuracy >99.5%
    Item Specifications Referenced B43905
    Performance Aperture current accuracy ± 0.4% of setting; Polarity error less than 0.5%
    Industry Standards 21 CFR Part 11
    Sample Volume Range 4 - 400 mL
    Particle Size Analysis Range 0.20|1,600.00|μm in diameter
    Sample Volume 4 - 400 mL
    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.
