Introduction

This chapter describes the physical features of the dispersion unit. It covers:

What the dispersion unit does

The sole purpose of any sample dispersion unit is to prepare the sample and then
deliver it to the optical bench so that it can be measured.
The Hydro 2000G and Hydro 2000S allow the Mastersizer to be used for particle-
in-liquid particle sizing. Functionally, the two dispersion units are virtually identi-
cal except that the Hydro 2000G can circulate 800ml of liquid while the Hydro
2000S has a smaller capacity of 150ml. The small volume of the Hydro 2000S is
ideal when using solvent dispersants or when samples and dispersants are either
expensive or hazardous.
The materials used in the manufacture of the dispersion units maximise the range
of samples which can be handled. Variable pump/stirrer speeds allow a wide range
of particle sizes and densities to be suspended and circulated, whilst a variable
power ultrasonic system enables particle agglomerates to be dispersed.
