Groups of particles are dispersed in a liquid medium and measured High-concentration samples can be measured using the laser diffraction method.
as they are circulated between the flow cell, which is placed in the
measurement unit, and a dispersion bath in the sampler. Measurement is possible by simply holding the high-concentration sample particles to be measured between two glass slides.
The dispersion bath incorporates a stirrer and an ultrasonic sonicator. Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required
A pump delivers the dispersed suspension to the flow cell. level of dilution, and a true image of the measurement object can be obtained.
The pump is specially designed to ensure both liquid medium and the Commercial hand creams, face creams, and rinses can be measured with hardly any pretreatment.
