Understanding your Mastersizer 3000

Particles are too small to measure directly – but by firing a laser beam at a sample and measuring the intensity of the light that gets ‘scattered’, we can accurately calculate a particle’s size. The Mastersizer 3000 is the world’s fastest, most accurate and most reliable instrument for doing this.

There are three key components: the optical bench that houses the laser and sensors; the sample dispersion units where you load samples for analysis; and the user-friendly software that helps you run, report and interpret your data.

  • Optical bench and laser

    This is the heart of the Mastersizer, housing the laser and detectors which measure particles from 10nm to 3.5mm. It uses both red and blue light and captures measurements across a wide range of angles.
  • Sample dispersion units

    The dispersion units deliver samples consistently and in the correct concentration. There are six wet dispersion units to handle the widest possible range of sample volumes and dispersants, and a dry dispersant system that handles rapid powder dispersion, even for fragile materials.
  • Intuitive software with ‘built-in expertise’

    The dispersion units deliver samples consistently and in the correct concentration. There are six wet dispersion units to handle the widest possible range of sample volumes and dispersants, and a dry dispersant system that handles rapid powder dispersion, even for fragile materials.

Frequently asked questions

Do I need to prepare the workspace prior to installation?

What customers use the Mastersizer 3000 for

The Mastersizer 3000 lets users find the particle size ‘sweet spot’ for a vast array of processes – helping them create substances that behave more predictably, more safely and to a higher quality. Mastersizers are frequently used for:

  • Creating smooth-flowing powders

    Many manufacturing processes need powders to flow smoothly. (Too small and flow is unpredictable; too large and the density of final products can be affected). It’s important for processes such as ‘additive’ manufacturing (like 3D-printing), and controlling the quality of sintered products.
  • Packing powders to the right density

    The way particles pack together depends on both their size, and the mix of differently-sized particles. Getting the balance right means denser packing. It’s essential for mould-based manufacturing (eg ceramic and metal components) as well as for processes such as powder coating.
  • Mixing stable dispersions

    Getting the particle sizes ‘just right’ in dispersions is the difference between creating a stable dispersion with evenly distributed particles, or one with agglomerations. (That’s the difference between an even powder coating or smooth-flowing paint, or dispersions with lumps in.)
  • Dissolving substances predictably

    Particle size directly affects the speed at which a substance dissolves. (Smaller is faster; larger is slower). This is particularly critical in the pharmaceutical industry, where this affects the release rate of the active components of a drug.
  • Controlling how particles are inhaled

    Particle size affects how easy it is for people to inhale substances. In both medicine and industry there are strict guidelines for particle sizes – broadly speaking, so that drugs are quickly and easily inhaled, and harmful substances (such as cleaning products and hairsprays) are not.
  • Deciding chemical reaction times

    Particle size determines volume-to-surface-area ratios, which affects chemical reaction times. Controlling reaction times is important in manufacturing processes such as the hardening of cement, and in producing effective catalysts (such as cleaning pollutants from medicines.)
  • Manipulating how light reacts with substances

    The particle sizes in pigments, paints and coatings affects how the final products scatter light. So by controlling the particle size, manufacturers can control how bright, strong or glossy something looks.
  • Improving the quality of food and drink

    The particle sizes in food and drink can have a dramatic effect on how they smell, taste and feel: the particle size of ground coffee affects its strength and brew time; smaller particles in chocolate give it a silkier mouth-feel and better quality.
