MASTERSIZER 3000 – Technology in the Laboratory

Considered as the main instrument for analyzing the finest particle size, the Mastersizer 3000 comes in a modular form designed to meet the requirements of the most modern research and quality control laboratories for high performance, flexibility, ease of use and the reproducibility of the result.

In our Laboratory in Cacciano (BI) the Laser granulometer is used to analyze the size of products with finer granulometry, in particular less than 100 microns. It is a fundamental tool for quality control of the various productions and for internal research and development.

How does it work?

The Mastersizer 3000 uses laser diffraction technique to measure the particle size distribution from 10nm down to 3.5mm.

A laser beam passes through a scattered sample of particulate matter and the angular change in intensity of the scattered light is measured. Large particles scatter light at small angles relative to the incident laser beam, and small particles scatter light at larger angles.

The angular diffusion intensity data is then analyzed for the calculation of the particle size. The particle size is reported as a sphere diameter equivalent to the volume.

The technique is based on the observation that light is diffracted by a particle with an angle inversely proportional to its size.


The Hydro EV is a sampling unit for suspensions and emulsions; it allows the complete ‘dissolution’ of any type of material to be analyzed in a laboratory beaker.
