Description

The Multisizer 4, the latest COULTER COUNTER designed with the SMART and DPP technologies, offers highly accurate and reliable particle counting and sizing

The Coulter Principle Goes Digital

While retaining and enhancing the analog circuits developed and refined by Coulter over many years - and the Digital Pulse Processor (DPP) used for the first time in the Multisizer 3 - the new Multisizer 4 incorporates the latest advances in both analog and digital circuits. High-speed digitalization of the signal enables the use of multiple parameters for more accurate particle characterization. Plus the possibility of dynamic size measurement is a reality on the Multisizer 4. The measurement data for each particle is analyzed and stored. The data can be analyzed and formatted in numerous ways, or stored and re-analyzed at a later date - no need to analyze the sample again.

Proven Technology

  • More than half a century of experience counting and sizing particles and cells
  • More than 6,000 documented references using the Coulter Principle and nine approved ASTM methods
  • Technology defined by the International Standard ISO 13319 Accurate sizing, counting and high resolution technology preferred by the industry for particle counting and size distribution
  • It provides size, based on direct measurement of a real parameter of a particle - its volume. Color or refractive index does not affect results
  • Capable of counting and sizing particles at concentration levels not detected by other technologies
  • Dynamic size measurement. Pulse time stamp allows size change measurement in real time

Superior Instrument Design

  • Ease-of-use. Instrument operation is completely controlled from the computer. Intuitive software with wizards are ideal for beginners, while simple menus assist experienced operators
