Particule size analysis dispersion system Hydro EV

small volumefluid

A unique dip-in wet sample dispersion unit that can be used with standard laboratory glassware. Suitable for a wide variety of dispersant volumes and particle size ranges. The Hydro EV has a unique dip-in centrifugal pump and stirrer design that achieves full and rapid dispersion in standard laboratory beakers, allowing close matching of the dispersant volume to the application requirements. Following measurement, the dispersion head can be raised out of the beaker, enabling quick cleaning and sample recovery. Compatible with 250mL, 600 mL and 1000 mL laboratory beakers. 40 W in-line sonication probe, for rapid agglomerate dispersion. Dip-in centrifugal pump and stirrer design. Sample easily recovered following analysis. Chemically compatible with a wide choice of organic and inorganic dispersants. Full software control of pump / stirrer and sonication. Integral sample tank light. How it works Dispersing a sample within a liquid involves wetting and separating each individual particle. The aim is to produce a stable, completely dispersed suspension for measurement. In order to promote wetting, it is vital to select an appropriate dispersant. Water is the one most commonly used and, when suitable, offers many benefits in terms of cost of measurement and sample disposal. However, non-aqueous dispersants may need to be used in some applications, such as those involving water soluble particles. The application of sonication promotes the wetting process, by disrupting the structure of any agglomerates. Stabilizers may also be added to the dispersant to prevent re-agglomeration.
