Particle size distribution analyzer

Products > Analytical > Particle size distribution > ELSZ-2000S


ELSZ-2000S measures particle size and molecular weight from dilute solution to concentrated solution. New auto temperature gradient function with an extended range from 0 to 90℃ completes melting point and phase transition point analysis. It is compatible with particle size range from 0.1nm to 10μm and concentration range from 0.00001% to 40%

 Features  (*newly added function)
  • *Higher sensitivity and shorter measurement time with new APD

  • *Melting point and phase transition point analysis enabled by auto temperature gradient function

  • *Wide temperature range between 0 and 90℃

  • *Wide range molecular weight analysis

  • Supports concentrated sample measurement
