Bettersizer 2600 – Particle size and shape analysis 0,02 – 3.500 µm

The Bettersizer 2600 is a reliable and extremely versatile measuring device for determining particle size distribution based on proven laser diffraction technology in the range of 0.02 – 2600 µm. If required, the upper measurement limit can easily be extended to 3500 µm using the dynamic image analysis module PIC-1, and this tool also offers the possibility of particle shape analysis with more than 20 available parameters. Thanks to its modular design, the Bettersizer offers various wet and dry dispersion modules for different applications in terms of sample preparation and conveying, which can be interchanged very quickly and flexibly during operation.

Your benefits:

  • Precise measurement from 20 nm, realistic measurement up to 3.5 mm

  • Combined size and shape analysis

  • Extremely flexible sample dispersion and conveying options

  • Perfect price-performance ratio

Thanks to the patented design of the Bettersizer 2600 optical system – a combination of Fourier and inverse Fourier setup with an obliquely positioned measuring cell, single-laser technology and high detector density – almost a continuous scattered light angle range of 0.016° – 165° can be covered. This allows both nanoparticles from 20 nm and coarse particles (up to 2.6 mm) to be reliably characterized. In combination with the dual CCD camera system of the PIC-1 module, which enables the reliable detection of coarse particles by means of dynamic image analysis, the Bettersizer 2600 allows realistic measurement up to 3.5 mm.

The PIC-1 can also be used to calculate over 20 different shape parameters from the individual images, e.g. aspect ratio, circularity, convexity and many more. The shape analysis can be carried out simultaneously with the size analysis or independently.

With four wet and two dry dispersing modules (see “Options” below for details), the Bettersizer 2600 offers an applicative solution for almost all sample types. Thanks to the practical slide-in technology of the measuring cells in the base unit of the main unit and an intelligent software solution, conversion between different dispersion units is quick, easy and a mouse click away. BT-802 (wet) and BT-902 (dry) are both standard dispersing modules that are sufficient for the majority of all applications. BT-804 (wet) and BT-903 (dry) are units optimized for small sample volumes. The fully automatic BT-80N Pro and semi-automatic BT-80N are suitable for applications involving organic solvents in particular.

The BT-A60 autosampler is a compact and powerful sampling system compatible with the Bettersizer S3 and 2600 series for automating particle size measurement in the laboratory and thus reducing costs. The system doses up to 60 samples fully automatically, regardless of whether they are in the form of a powder or a pre-dispersed liquid dispersion. The integrated barcode printer ensures that the results are saved to the corresponding, correct sample. The sampler is cleaned automatically using ultrasound to prevent contamination.

  • Effective, automatic cleaning with ultrasound
  • Suitable for powders or dispersions
  • Sampling volume: 0.5 – 5 ml

The fully automatic wet dispersion unit BT-802 is compatible with the Bettersizer 2600 and designed for samples that can be measured in aqueous media, ethanol or ISO propanol. The medium is supplied and removed by a peristaltic pump, the sample is conveyed through the measuring cell by a centrifugal pump. The dispersion bath is made of stainless steel. The unit is controlled via the Bettersizer software (manually for individual tests or fully automatically via SOP for routine measurements).

The semi-automatic small volume wet dispersion unit BT-80N is compatible with the Bettersizer S3 and 2600 series devices and is ideal for reproducible particle size measurement in polar and non-polar solvents. Due to the small amount of liquid (approx. 50 – 80 ml), the consumption of solvent is low. The effective and controllable sonication with ultrasound enables the measurement of systems that are difficult to disperse and react glomerating.

Cleaning and changing samples or solvents is very easy thanks to the quick-lock system. The sample is fed to the Bettersizer 2600 via a solvent-resistant tube and is controlled manually.
