Sample tank
The sample tank can hold up to 120 ml (Hydro MV) or 600 ml (Hydro LV) of sample and
dispersant prior to circulation through the wet cell situated in the measurement area of
the optical bench.
The sample tank is normally filled using the dispersant inlet ports, though sample and dis-
persant can be poured directly into the tank if required. A light positioned in the dis-
persion unit body above the tank will flash briefly when the tank is filled to the correct
level.
Additionally the tank contains a pump and stirrer assembly, while an ultrasonic trans-
ducer attached to the tank helps to disperse the sample.
Once a measurement has finished, the tank can be emptied automatically using a drain
valve in the base of the tank. The sample fluid is emptied through the drain pipe out to a
sink or other waste container.
All functions of the tank area are controlled by the Mastersizer software.
