This is a particle size measurement system (particle size 0.6 nm - 10 μm) that uses the `dynamic light scattering method` (DLS method).
Various functions are included to further improve quality control.
It measures in high speed (approx. 1 minute) and it is also lightweight and compact which is essential for use in laboratories, and this new optical system is able to measure multiple samples at one time with a wide concentration range from dilute to concentrated.
In addition, it is a new product not immersed in the liquid (non-immersion type), so contamination is not an issue and up to 5 samples can be measured without stopping, when used without the autosampler.
FEATURES
- Up to 50 samples in a row
- Add samples as measure
- Set samples in place easily
- Replace up to 50 samples at once
- For organic solvents (Glass disposable cell)
- Sample vol. 0.4 ml ~
