The Hydro EV uses a standard laboratory beaker [1] to hold the sample and dispersant
liquid.
Note: 600 ml and 1000 ml beakers are recommended.
The pump head [2] tilts back allowing the insertion of a beaker that contains dispersant.
The pump head is then tilted forward, lowering the pump arm into the beaker. If the
pump head is raised at any time, the pump will automatically stop.
The pump is controlled by the software, circulating dispersant from the unit to the wet
cell [3] located in the optical bench. Sample must be added manually to the beaker.
A stirrer [4] agitates the sample to prevent settling.
Use of the ultrasonic transducer can also aid sample dispersion and remove bubbles.
