4.4.2 Components of Reaction Disk Unit
The reaction disk unit consists of reaction disk movement assembly and reaction
compartment assembly.
Reaction Disk Movement Assembly: It consists of disk assembly and disk drive
assembly. It holds cuvettes and carries them to the expected postion for
Sample/Reagent dispensing or stirring. Also the photometric measurement is carried
out when the reaction disk is rotating. The disk drive assembly includes the coder
sensor assembly, motor assembly and drive shaft assembly.
Coder Sensor Assembly: The function is to find the mechanical zero position and
count the valid edges of the coder.
Motor Assembly: It drives the reaction disk to rotate via the belt and the two belt
wheels.
Reaction Compartment Assembly: It provides a constant-temperature environment
for the reaction and consists of the compartment assembly and up cover assembly.
