Particle size analyzer Mastersizer 3000+ Lab

The Mastersizer 3000+ Lab is an entry level system for particle size analysis by laser diffraction. This system offers robust size measurements from 0.1 to 1000 microns and benefits from the core experience of the Mastersizer Xplorer software.

The Mastersizer 3000+ Lab provides a cost effective, entry level particle sizing experience which can be upgraded as required.

The Mastersizer 3000+ Lab uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analysed to calculate the size of the particles that created the scattering pattern.

A typical system is made up of three main elements:

Optical bench: A dispersed sample passes though the measurement area of the optical bench, where a laser beam illuminates the particles. A series of detectors then accurately measure the intensity of light scattered by the particles within the sample over a wide range of angles

Sample dispersion units (accessories): Sample dispersion is controlled by a range of wet and dry dispersion units. These ensure the particles are delivered to the measurement area of the optical bench at the correct concentration and in a suitable, stable state of dispersion

Instrument software: The basic Mastersizer Xplorer software controls the system during the measurement process and analyzes the scattering data to calculate a particle size distribution
