Hardware overview
Fluid system
The fluid system consists of all the valves, pumps, tubing, syringe, fluid sensors, water
and waste containers, the wash station, and the probe. It transports all fluids around
the instrument, including sample, reagent, calibrator, control, diluent, cleaner,
system water, and waste. The fluid system also delivers the correct amounts of fluids
to the cuvettes.

To prevent overflow of the internal waste tank when the system is in Standby status, the
waste is periodically pumped to the external waste container. (Condensation can build up
in the cooling assembly while the system is in Standby status.)
