Beckman Coulter Multisizer 3 Particle Counter

Beckman Coulter Multisizer 3 Particle Counter

Cambridge Scientific ID #'s: 18327, 14506, 11269

Includes Computer loaded with Software

 

Provides Number, Volume, Mass And Surface Area Size Distributions In One Measurement, With An Overall Sizing Range Of 0.4 µm To 1,200µm. Its Response Is Unaffected By Particle Color, Shape, Composition Or Refractive Index. Includes: Hp

The most versatile and accurate particle sizing and counting analyzer available today. Using The Coulter Principle, also known as ESZ (Electrical Sensing Zone Method), the Multisizer 3 COULTER COUNTER provides number, volume, mass and surface area size distributions in one measurement, with an overall sizing range of 0.4 µm to 1,200 µm. Its response is unaffected by particle color, shape, composition or refractive index. The Coulter Principle is the absolute leading technology in high resolution and accuracy and it is further enhanced in the Multisizer 3 by using a Digital Pulse Processor (DPP). You will get the ultra-high resolution, multiple channel analysis and accuracy not provided by any other technology. It all makes the Multisizer 3 indispensable for any industrial or life science research project involving sizing and/or counting. Equally a powerful tool for quality control, it provides the analyst with a system which is easy to use, yet so technologically advanced that it is able to solve most particle sizing problems.

Beckman Coulter Z2 Particle Counter

Beckman Coulter Z2 Particle Counter

Cambridge Scientific ID #'s: 12669, 12488

The Z2 COULTER COUNTER is the latest addition to the Z Series COULTER COUNTER. In addition to reporting both count and concentration results, the Z2 adds the ability to provide size distribution of the cell population. The Z2, like the Z1, uses the Coulter Principle (Electrical Sensing Zone Method) of counting and sizing of cells. This technique provides accuracy, speed, versatility and reproducibility. The Z2 displays the entire size distribution graph, or the size statistics and counts between user selectable areas of the graph. In addition, this instrument displays the cumulative count and the cumulative number % above and below a size determined by the cursor positioned on the graph. Additional Benefit, Averaging Data The Z2 has the ability to average counts and channelized data from a series of up to 10 consecutive analyses. The more cells counted and sized the greater the statistical confidence in the result and the smoother the shape of the averaged size distribution.

 

Includes:

  • Control Panel/Keyboard
  • 100 micron aperture
  • All Necessary Cords, Cables
  • Manual

 

Performance Specifications

  • Mercury Free
  • Sample result averaging
  • Size distribution graph and tabular data
  • Small Footprint
  • One-Button Calibration
  • User test functions built-in
  • Storage of up to 5 instrument settings for different cell lines
  • Technology defined by the International Standard (ISO 13319:2000: Determination of particle size distributions -- Electrical sensing zone method)
