2. General description of the analyser
In mechanical terms, the analyser is divided up into subassemblies. Each subassembly has its own electronic board
for controlling the individual subassembly elements.
All the subassemblies are electrically connected by the CAN bus cable. e CAN bus cable contains the power wires
and the wires that transmit information between the boards.
A list of the subassemblies is given below:
• Sample rotor
• Reagent rotor
• Reaction rotor
• Pipetting arm
• Stirring arm
• Wash station
• Dispensing pumps
• Fluidic system
• Washing solution and high contamination waste bottles
• Electrical and communication connections
• ISE module (optional)
2.1. Sample rotor
e sample rotor is comprised of a drum for positioning the samples, a cover and a barcode reader.
e drum has a circular structure with 3 concentric rings in which the tubes or sample wells are placed.
Each of the 3 rings has 45 positions for tubes with diameters of between 12 and 16 mm and heights of up to 100 mm
e barcode reader can only read the primary tubes with codes located in the two outer rings.
e accessories box has some adapters for insertion in each of the positions in the event that they must contain
sample wells instead of primary tubes.
e positioning of the serum in the rings is not really relevant but the following positioning is recommended:
Calibration serums, controls and special solutions (such as washing and dilution solutions) should be placed in the
innermost ring, in sample wells. Samples should be placed in the two outer rings in primary tubes so that they can
be read by the barcode reader.
2.2. Reagent rotor
e reagent rotor is comprised of a drum for positioning the samples, a cover and a barcode reader. e whole as-
sembly is refrigerated.
e drum has a circular structure with 2 concentric rings with positions for inserting the reagent bottles.
Each ring has 44 positions.
e barcode reader can read the codes of the bottles positioned in both rings.
ere are 2 types of bottle: some have a capacity of 60 mL and others have a capacity of 20 mL.
e 20 mL bottles can only be placed in the outer ring.
