•Laser Diffraction Particle Size Analyzer SALD-300V
[Standard Model for Analyzing Sub-micron Particles]
This analyzer uses a blue-violet semiconductor laser (wavelength: 405 nm), which allows it to measure sub-micron particles. It is a wet-type
instrument that is ideal for the measurement of samples with relatively small specific gravities, such as food products, drinks, pharmaceuticals,
cosmetics, emulsions, pigments, and paints. It reliably captures blue and black fine/ultrafine particles, a task that was difficult with earlier
methods.
•Model 1 (measuring unit only) •Model 2 (measuring unit and sampler)
Measurement range: 0.1 to 50 µm Measurement range: 0.1 to 350 µm
Cell: Dedicated batch cell Cell: Batch cell/flow cell

•Laser Diffraction Particle Size Analyzer
SALD-200VER
[Standard Model]
A high-performance, low-cost, space-saving, wet-type instrument that is ideal for the measurement of samples with relatively low specific
gravities, such as food products, drinks, pharmaceuticals, cosmetics, and emulsions.
•Model 1 (measuring unit only) •Model 2 (measuring unit and sampler)
Measurement range: 0.25 to 50 µm Measurement range: 0.25 to 350 µm
Cell: Dedicated batch cell Cell: Batch cell/flow cell

A high-concentration sample measurement system is available as an option for the SALD Series.
Principle of High-concentration Sample Measurement System
The influence of multiple scattering is avoided by enclosing the sample between two glass
Glass plate (slide glass) plates, thereby making the optical path length as short as possible. This system allows
samples for which the particle size distribution changes due to dilution to be measured in the
undiluted state, or with the absolute minimum dilution, and real images of the samples to be
obtained.
