Assembly
5.3.1
Installing the Rotating Arm
1. Position the flat side of the motor shaft so it is facing out as shown in Figure 5.1.
2. Place the rotating arm on the motor shaft as shown in Figure 5.2, pushing down as far as possible.
3. Tighten the shaft locking screw with a #2 Phillips screwdriver as shown in Figure 5.3.
5.3.2
Installing the Quartz Flow Cell
1. Remove the flow cell carefully from the packaging. The flow cell should be clean, and care should be
taken to prevent fingerprints, especially in the middle region of the flow cell where the light beam passes
through. (Wearing gloves is recommended.)
2. Insert the flow cell into position under the flow cell header as shown below in Figure 5.4. Align the black
dot on the flow cell with the black dot on top of the white plastic flow cell guide.
3. Carefully and slowly lower the clamp ensuring it is aligned with the flow cell as shown in Figure 5.5 and
Figure 5.6. The flow cell clamp should not require much force when clamping down. If any significant
force is required, try adjusting the position of the flow cell to prevent damage.
