Malvern Mastersizer 3000E

Entry level particle size analyzer

The Mastersizer 3000 is highly regarded as the premier laser diffraction particle size analysis instrument on the market for design, performance and software user experience. However, some customers do not immediately need the advanced functionality that the Mastersizer 3000 offers. Malvern Panalytical have therefore introduced an entry level instrument to the Mastersizer product family which is based upon the proven design of the Mastersizer 3000 but with more basic performance and software functionality.

 

Overview

The Mastersizer 3000E provides a cost-effective, entry level particle sizing system which can be upgraded as required. It is available with two different performance levels:

Mastersizer 3000E Basic

  • Particle size range from 0.1 – 1000µm
  • Manual dispersion units only
  • Basic software, with updates and bug fixes only
  • Anytime upgrade option to Mastersizer 3000E Extended

 

Mastersizer 3000E Extended

  • Automated wet sample dispersion units supported
  • All the advanced software functionality offered with the Mastersizer 3000, including updates, bug fixes and upgrades

 

How it works

The Mastersizer 3000E 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 Mastersizer 3000E software controls the system during the measurement process and analyzes the scattering data to calculate a particle size distribution.
