These are the following:
 Tank
The tank can hold up to one litre of sample and dispersant for circulation through
the cell of the optical bench.
Warning!
Due to the possible risk of sonication of the blood and its unknown effects,
never place fingers in the tank when the ultrasonic probe is in operation.
Also, never put fingers in the tank when the pump/stirrer shaft is rotating.
Sample and dispersant can be poured directly into the tank. If this is done, do not
cause the tank to overflow by filling it too quickly. Clean any spillage off the covers
immediately to prevent damage.
 Pump/stirrer
The stirrer, located in the base of the tank, agitates the sample/dispersant mixture.
The pump circulates the sample through the flow cell located in the sample area of
the optical bench. The pump and stirrer speeds are controlled independently by the
software.
Warning!
Never put fingers into the tank when the pump/stirrer shaft is rotating.
Caution!
Never operate the pump/stirrer at more than half speed with the tank
empty.
 Ultrasonic probe
Warning!
Due to the possible risk of sonication of the blood and its unknown effects,
never put fingers in the tank when the ultrasonic probe is in operation.
The ultrasonic probe is used to help disperse samples. The power of the probe is
controlled through the software.
 Level sensor
The level sensor automatically stops the tank being filled above a certain level. If
the tank fails to fill properly then the level sensor may require cleaning or the
