5. Fluidic elements
e analyser operates with 4 tanks for processing uids. ese tanks are: the distilled water tank, low contamination
waste tank, washing solution tank and high contamination waste tank.
e distilled water and low contamination waste tanks are located at the bottom rear part of the analyser, and can
only be accessed by the technical service. Full and empty level control is executed through a double-buoy system.
e washing solution and high contamination waste tanks are located at the front bottom part of the analyser. ey
can be accessed directly by the user.
• Once the determination has been made, the reagent and sample mixtures are sent to the high contamination
waste tank. e tank has a capacity of 5L and autonomous operation of at least 20h.
• e tank that contains washing solution has a capacity of 5L and autonomous operation of at least 8h. e
washing solution is used in the wash station to clean the reaction rotor and during the analyser initialisation
and nalisation processes.
• All the waste from the reaction rotor wash station is deposited in the low contamination waste tank, in addition
to the waste from the tip and stirrer wash stations. e tank has a capacity of 5L and automatically empties the
content outside the apppliance through a buoy control process. e system uses the SF1-B5 pump to empty
the tank.
• e internal distilled water tank has a capacity of 5L. e water is used to prime the pipetting system, wash the
inside and outside of the sample and reagent tips and wash the reaction rotor. e tank has two water inlets that
are selected by the software. One inlet is from an external tank. For this purpose the analyser uses the SF1-EV2
and the SF1-B4 pump. e other inlet is through a water mains connection. When the water mains connection
is selected, in the event that there is pressure, only one SF1-EV1 electro valve is used.
e analyser uidic diagram is shown below.
