Description

The Malvern Mastersizer 2000 & Hydro 2000MU measures particle size distributions using laser diffraction, with a measurement range of 0.02–2,000 µm. Combining red and blue light sources, it analyses particles across a broad size range within a single system. This makes it suitable for laboratories investigating fine particles alongside larger material. Applications include research, product development and quality control, where particle size can influence material performance and processing behaviour. With the appropriate dispersion accessory, the Mastersizer 2000 supports both wet and dry sample analysis.

Included with the system is the Hydro 2000MU dispersion unit. This accessory prepares and circulates liquid-dispersed samples for particle size analysis with the Mastersizer 2000. Its manual operation gives users direct control over sample preparation, making it suitable for routine testing and method development. The unit uses a 1,000 mL beaker as its sample container, providing convenient access for adding samples and dispersants. A dip-in pump and stirrer keep particles suspended while circulating the mixture through the analyser’s measurement cell, helping maintain a representative sample throughout the measurement process.

Users can adjust dispersion conditions to suit the sample, balancing effective mixing with the need to protect fragile particles. Additionally, the accessible beaker arrangement simplifies sample changes and cleaning between measurements. Suitable applications include powders, minerals, ceramics and pharmaceutical materials that require wet dispersion before analysis. When paired with a compatible Mastersizer 2000, the Hydro 2000MU provides a practical solution for laboratories investigating particle size in research, product development and quality control.
