Precautions
:
1. The synchronous belt wheel which is fixed to stepping motor should keep the same
installation height with the matched belt wheel so that the belt does not bear twisting
force.
2. Use the BA30-K22 fixture to get appropriate tensile force of horizontal synchronous belt
and use the the BA30-K21 fixture to get appropriate tensile force of vertical
synchronous belt.
3. The direction of horizontal and vertical stepping motors’ plug should face outside and
upside respectively.
4.
Disconnect correlative power cables, data cables and liquid connecting before
performing the above steps.
4.3 Sample/Reagent Disk Unit
4.3.1 Function Introduction
The sample/reagent disk unit holds the sample tubes and reagent bottles and carries them
to the specified position for aspirating sample or reagent. At the same time it is capable of
refrigerating so as to keep the reagent stable and prevent it from volatilization.
1. Holding sample tubes: Sample containers (tube, microtube, etc) are placed on the
sample/reagent disk unit, and then the sample probe unit aspirates sample and
dispenses them into reaction cuvette.
2. Holding reagent bottles: Reagent bottles are placed on the sample/reagent disk unit,
and then the sample probe unit aspirates reagent and dispenses them into reaction
cuvette.
3. Programmed feeding: The sample/reageng disk unit carries specified sample tubes or
reagent bottles to the aspirating position for aspirating according to the programmed
period. The sample/reagent disk is driven by the drive assembly.
4. Reagent refrigerating: The sample/reagent disk unit is capable of refrigerating and
keeping the reagents at 4-15°C for 24 hours a day so that the reagents are always
stable and not volatilized.
4.3.2 Components of Sample/Reagent Disk Unit
The sample/reagent disk unit consists of reagent refrigerating assembly, disk drive
assembly and disk assembly. See Figure 4-10.
