3. Mechanical elements
In mechanical terms, the analyser has a tubular structure to which the dierent subassemblies and housing elements
are attached.
e analyser has the following subassemblies:
• Sample rotor
• Reagent rotor
• Reaction rotor
• Pipetting arms
• Stirring arms
• Wash station
• Dosing system
• Fluidic system
• ISE module (optional)
3.1. Sample rotor
e tubes with the patient serum samples and the wells with the calibration standards and controls are placed in the
sample rotor. e rotor (3) has 3 rings. Tubes with larger diameters (16 mm) are placed directly in the holes. Tubes
with smaller diameters or sample wells require the use of adapters (2) to secure them in place.

Figure 3.1 Sample rotor assembly
e rotor (3) has a single position once it has been inserted into its compartment (4). For this reason it has a cen-
tring device (6) to guide it. Once inserted, the rotor cannot be removed as it is blocked by a ball-shaped anchoring
device (7). To release the rotor from the base it is necessary to press the button (5).
e rotor vessel (9) is secured to the rotor assembly support (10). e rotor (3) is connected to the rotor centring
device, which in turn is connected to the pulley by a shaft (14). e belt (13) transmits the motor movement (11)
to the whole assembly.
