Bettersizer 2600 – Particle size and shape measurement 0.02 – 2600 µm

The Bettersizer 2600 is a compact and highly integrated analyzer of the latest generation for the analysis of particle size distributions according to the principle of static light scattering (laser diffraction). The modular design of the Bettersizer 2600 combines two widely used sample preparation and supply mechanisms in one instrument. Depending on the application, the operator can choose between two detached, fully automatic dispersion modules, being integrated into the measuring software: BT-802 for wet dispersion in liquid media or BT-902 for dry dispersion by means of compressed air.

Short-wave laser light (635 nm) hits the particles during size measurement and is scattered elastically dependent on the particle size. The permanently installed detectors determine the angle dependency of the scattering intensity in forward, sideways, and backwards direction – this is enabled by the unique design of the optical bench, based on the combination of Fourier setup and Inverse Fourier setup. Data editing by either Fraunhofer or Mie theory delivers the volume-based particle size distribution of the sample.

Bettersizer 2600 – scheme of optical bench

Besides the ideal price-performance-ratio, the Bettersizer 2600 offers the following essential advantages:

    • Innovative optical system: combined Fourier and Inverse Fourier setup

    Due to the patented setup of the optical system – a combination of Fourier and Inverse Fourier setup – nanoparticles (20 nm upwards) as well as coarse particles (up to 2.6 mm) can be analyzed reliably. The scattered light is detected in forwards, sideways, and backwards direction. The additional skewed measurement cell enables the detection in a continuous angle range, the usage of just one laser delivers a continuous scattering spectrum with consistent wavelength.

    • Standard Operation Procedures (SOPs)

    enable an easy and standardized measurement procedure for maximum reproducibility.

    • Fast and simple switch from wet to dry measurement

    The change between wet and fully automated dry dispersion of the Bettersizer 2600 with venturi valve and compressor, as well as powder suction, can be executed in less than a minute.

    • Automatic laser centering function

    guarantees an ideal adjustment of the optical measurement system for maximum reproducibility.

Accessories

With the solvent resistance option and the additional dispersion unit BT-800N, measurements can be performed in all common solvents on the Bettersizer 2600. The reduced bath volume compared to the standard dispersing unit enables economical use of solvents, the modular design of the measuring system and the self-sufficient operation of the dispersing unit BT-800N guarantees a quick and easy exchange of the dispersing modules without inconvenient cleaning or further modifications to hardware and software. Analogous to the standard dispersion, a visible sample preparation by stirring and ultrasonic is possible.

  • Sample volume < 300 ml
  • Ultrasonic: 50 Watt bath-sonication
  • variable pumping or stirring speed (0 – 2500 rpm)
  • appropriate for aqueous, polar and non-polar solvents

The external small-volume cell is ideally suitable for reproducible particle size measurement in polar and non-polar solvents. Due to the small amount of liquid, solvent consumption is low. The effective and controllable ultrasonic irradiation enables the measurement of systems that are difficult to disperse or tend to reagglomeration.

Cleaning and changing samples or solvents is very easy thanks to the quick release system. The sample feed to the Bettersizer 2600 is carried out via a solvent-resistant hose and is manually controlled.

External small-volume cell - add option
  • Sample volume around 90 – 120 ml
  • Stainless steel agitator vessel with centrifugal pump and quick-release mechanism
  • Ultrasonic system: power: up to 200 Watt; frequency: 26 kHz – adjustable amplitude (20 – 100 %) – programming of maximum energy input
  • Touch display and automatic data storage and remote control
  • suitable for aqueous, polar and non-polar solvents
