4.4 Reaction Disk Unit
4.4.1 Function Introduction
The reaction disk unit holds reaction cuvettes and rotates clockwise, carrying the
cuvettes to specified position for sample/reagent dispensing and stirring. The reagents
and the sample react in reaction cuvette. Also the reaction disk unit provides a
constant-temperature environment for the reaction.
Figure 4-20 shows the position on the reaction disk. No.1 is dispensing R1/R2/S position.
No.2 is aspirating pre-diluted sample position. No.5 is photometric measuring position.
No.10 is stirring position. No.25~No.29 is for replacing the cuvettes manually.
