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.

Besides the ideal price-performance-ratio, the Bettersizer 2600 offers the following essential advantages:
* The measuring range depends on the sample.

The autosampler doses fully automatically up to 60 samples no matter if they are dry powders or pre-dispersed liquid dispersions. The included barcode printer ensures that the results are recorded for the corresponding sample. The sampler is cleaned by ultrasound to avoid contamination.
With this unit, small sample volumes can be dosed quickly and reliably. You can see what this looks like in the video using 200 mg of quartz sand as an example:
With the solvent-resistant BT-800N dispersion unit, measurements in all common solvents can be carried out on the Bettersizer 2600. The reduced bath volume compared to the standard dispersion unit enables the economical use of solvents. The modular design of the measuring system and the autonomous operation of the BT-800N dispersion unit guarantee fast and easy replacement of the dispersion modules, without inconvenient rinsing or additional changes to hardware or software. Analogous to standard dispersion, visible sample preparation by means of stirrer and ultrasonication is possible.
The BT-80N external small volume dispersion unit is ideally suited for reproducible particle size measurement in polar and non-polar solvents. Due to the small volume of liquid, the consumption of solvent is low. The effective and controllable ultrasonication allows the measurement of difficult to disperse and reagglomerating systems.
Cleaning and a sample or solvent change is very easy due to the quick-lock system. The sample feed to the Bettersizer 2600 is realized via a solvent resistant tube and controlled manually.
By means of this external, controllable ultrasound option, the measurement of difficult-to-disperse and reagglomerating systems is made possible.
