Product Overview

The Malvern Mastersizer 3000+ Pro a cost-effective mid-tier system that makes particle size analysis the easiest it’s ever been. It provides the highest quality data for applications needing micron scale sizing capabilities. Using the same class-leading hardware and easy to use Mastersizer Xplorer software in the series, Mastersizer 3000+ Pro is fast and accurate for both wet and dry dispersions. It provides data you can rely on, no matter your experience level. If requirements change it can be upgraded with added software features to the Mastersizer 3000+ Ultra.

The Mastersizer 3000+ Pro is made up of an optical bench, one or more automated sample dispersion units, an optional dispersion imaging accessory and software for instrument control and data processing. The folded optical design creates a compact system that requires very little bench space. The He-Ne 632.8nm laser enables measurements from 0.1 to 1000 microns. A rapid 10 kHz data acquisition rate and excellent reproducibility allows even highly polydisperse samples to be measured quickly and accurately.

Particle size is measured using the technique of laser diffraction. Samples are dispersed in either a liquid or an air cell. A laser beam passes through the cell and the dispersed particles scatter the light creating a scattering pattern. The optics measure the angles and intensity of the scattered light from which the particle size distribution is calculated using Mie Theory.

The Mastersizer Xplorer software controls the system during the measurement process and analyses the scattering data to calculate a particle size distribution. User guidance is provided through every stage of the measurement from method development, SOP operation to result reporting. Data quality guidance, SOP architect offer AI driven support that help every user develop better methods more quickly and make good data excellent.

Characterisation of Battery Materials
An important aspect in the design of the battery material is the particle size and particle size distribution of the materials used within the electrodes. Small particle size electrodes increase the rate of electrochemical reactions while large larger particle sizes increase energy storage capacity. Using a mixture of coarse and fine battery materials is one way to meet the requirements for power and storage capacity.

Optimising Powder Properties used in Additive Manufacturing (AM) or 3D-printing
Particle size distribution is critical for powder bed AM processes since it affects powder bed packing and flowability which in-turn impacts on build quality and final component properties. Powder flow is a critical consideration in the manufacture of sintered products using AM. Poor flow during powder bed deposition may lead to variations in powder bed density, resulting in defects that reduce the strength of the finished part. Packing density or the way that particles pack together is a function of both their size and size distribution. Minimising voidage is also crucial to producing a flaw-free sintered component.  

Particle size analysis in the Cement Industry
In a cement laboratory, traditional Blaine measurement can be a time-consuming and prone to operator variability. The Mastersizer 3000 offers highly automated particle size analysis with extremely high reproducibility and repeatability. Complete size distributions can further understanding of how certain size fractions correlate with performance which makes it possible to control and optimise milling and minimise both energy consumption and operating costs.

Measuring the particle size of foods such as dairy, margarine, chocolate, coffee, sugar etc.
Particle size measurement is essential in the development of new products, during manufacture and for final QC. Particle size distribution can affect taste, appearance, texture, processability, functionality and/or the stability of the final product.

Investigating the dispersion of Pharma dry powders and APIs
Control of particle size is critical during the formulation and manufacture of pharmaceutical products. Particle size can influence dissolution, solubility, bioavailability and stability. The unique design of the Aero S dry powder disperser avoids particle-to- wall collisions leads to gentle but effective dispersion, extending dry measurement to more fragile powders.

Importance of particle sizing of powder coatings, paint, inks and pigments
Powder coatings are dry powder polymers that contain pigments and are usually applied electrostatically as a free flowing dry powder and then heated to flow into a hard finish. Close packing of particles enables efficient melting at lower temperatures, giving more time for cross-linking reactions between polymer particles for a better finish. To produce a consistent coating the powder must be free-flowing and have a controlled particle size distribution which can be measured simply and rapidly by laser diffraction, using a dry dispersion method.

Classify soil texture using laser diffraction particle size analysis
The Mastersizer 3000 can be used in soil analysis to rapidly determine clay, silt and sand fractions to classify soil texture which as a result guides their use and efficient management.

Optimise reaction rates of catalysts
Reaction rates in solid systems are often a function of the specific surface area of the particles involved. The finer the particles, the larger their surface area to volume ratio, which promotes higher reaction rates. This is important in industries such as catalyst production, where particle size must be tailored to optimise reaction rates or ensure the effective scavenging of pollutants.
