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

in the cooling assembly while the system is in Standby status.)
