Hydro series wet dispersion units — overview
Sample dispersion units prepare and deliver sample to an optical unit so that it can be
measured.
The Hydro dispersion units create a suspension of particles in liquid media which enables
particle-in-liquid size measurements of both aqueous and non-aqueous samples to be
made by the Mastersizer.
A variable power ultrasonic system additionally enables particle agglomerates to be dis-
persed.
