Bettersizer ST Laser Particle Size Analyzer

Bettersizer ST – Particle size measurement 0.1 – 1,000 µm

The Bettersizer ST is a compact, highly integrated instrument for the analysis of particle size distributions. It analyzes particle size distributions according to the principle of static light scattering (laser diffraction). Short wavelength laser light (635 nm) hits the particles to be characterized and is elastically scattered depending on the particle size. The stationary detectors determine the angular dependence of the scattering intensity in forward, lateral and reverse direction. Data preparation according to either Fraunhofer or Mie theory provides the volume-based particle size distribution of the sample.

In addition to the optimal price-performance ratio, the Bettersizer ST has the following essential advantages:,

  • Dual Lenses optical system (DLOS)

is a patented technology of the Bettersize instruments and integrates forward, sideways and backward scattering to double the scattered light. Compared to simple lens systems,DLOS improves resolution and measurement accuracy, compared to multi-laser systems, DLOS enables more consistent results through laser technology.


  • Standard Operating Procedures (SOPs)

allow a simple and standardized measuring procedure for highest reproducibility

  • Auto centering function

guarantees an optimal adjustment of the optical measuring system for highest reproducibility

  • Accuracy calibration
  • Auto circulation & dispersion system



  • Particle size measuring range for: 0,1 – 1.000 µm (wet dispersion)
  • Innovative optical system: Dual Lenses optical system (DLOS)
  • Duration of a measurement < 1 min
  • Easy operation and data management for quality control
  • Ideal price-performance-ratio
