Bettersizer 2600 - Wet or Dry Particle Size Analyzer

The Bettersizer 2600 from Bettersize Instruments can measure particle size using either a wet or dry method.

This versatile, powerful particle size analyzer is suitable for a wide variety of measurement applications thanks to its modular design and patented technologies. The Bettersizer 2600 allows users to easily and accurately characterize materials from 0.02 μm to 2600 μm.

Features and Benefits

  • Powerful laser diffraction technology
  • Wide particle size range, able to measure wet dispersion from 0.02 - 2600 μm and dry dispersion from 0.1 - 2600 μm
  • Five state-of-the-art wet and dry dispersion modules accommodate a diverse array of dispersing particle systems.
  • New, patented technology employing Fourier and Inversed Fourier optical systems enables the precise measurement of large and small particles across a broad range.
  • Robust optical bench featuring 92 detectors, covering an angular range of 0.016 ° - 165 °
  • A small volume dry dispersing module can accommodate small sample quantities - ideal for pharmaceutical samples or valuable materials in short supply.
  • Rapid, straightforward changeover between dispersing modules
  • Users can create and implement Standard Operation Procedures for new materials with ease.
  • Refractive index measurements offer a more accurate parameter for result calculations.
  • Easy-to-learn, user-friendly software
