Hydro MV and LV — basic operation
This section provides an overview of the working principles of the Hydro MV and LV.
These units operate in essentially the same way; a Hydro LV dispersion unit is shown in
this illustration.

The tank [1] holds the sample and dispersant. Dispersant is added to the tank via the
lower internally regulated inlet port or the upper externally regulated inlet port. These
ports are controlled by the software. Alternatively, the dispersant can be manually added
into the tank.
When the dispersion is filled to the correct level an internal light will flash. The software
activates a pump, which circulates dispersant to the wet cell [2]. Sample is then manually
added to the tank where a stirrer prevents settling or separation.
An ultrasonic transducer can also be used to aid dispersion and remove bubbles.
