1.3 Functions
The general working procedure of the BS-120/BS-130/BS-180/BS-190 is as
follows:
1. All mechanical units are initialized.
2. The sample/reagent disk rotates to R1 aspirating position, and the probe
aspirates reagent from a bottle on the sample/reagent disk.
3. The reaction disk carries the cuvettes to the sample/reagent dispensing
position, and the probe dispenses reagent to a cuvette.
4. R1 is incubated in reaction cuvette for several periods.
5. The sample/reagent disk rotates to sample aspirating position, and the
reaction disk carries the cuvettes to the sample/reagent dispensing
position, then the probe dispenses the sample in the reaction cuvette.
6. With sample dispensed, the reaction cuvette rotates to mixing position for
stirring.
7. In case of single-reagent tests, the reaction begins. When defined time is
over, the reaction ends.
8. In case of double-reagent tests, when sample is dispensed and sirred, the
sample/reagent disk rotates to the R2 aspirating position, and the probe
aspirates reagent from the specified bottle on the reagent disk.
9. The reaction disk carries the cuvettes to the sample/reagent dispensing
position, and the probe dispenses reagent to a cuvette.
10. With R2 dispensed, the reaction cuvette is carried to the mixing position
for stirring.
11. During the first and second rotation of each period, the reaction cuvette
receives photometric measurement.
