Connecting To A Drip Tray - Waters 2410 Operator's Manual

• 5/16-inch open-end wrench
• Waste container
To connect the 2410 refractometer to waste:
1. Cut the minimum length of tubing needed, as described in Section 2.5.1, Connecting a
Column or Second Detector.
2. Slide the compression fitting and ferrule over one end of the 0.040-inch tubing, as
shown in Figure 2-5.
3. Bottom the tubing in the outlet tubing port fitting of the refractometer, then seat the
ferrule by tightening the compression screw 3/4-turn past finger-tight with the 5/16-inch
open-end wrench.

4. Place the waste container lower than, or at the same level as, the 2410 refractometer.
5. Place the free end of the tubing in the waste container.
Attention: The maximum pressure for the 2410 refractometer flow cell is 100 psi. The
STOP
flow cell could be damaged if this pressure is exceeded.

2.5.3 Connecting to a Drip Tray

The 2410 refractometer contains a drip tray underneath the flow cell behind the front panel to direct
solvent leaks to the front of the unit.
Connecting the drip tray is usually unnecessary, but, if you connect it, be sure to position the waste
container below the drip tray outlet.
Required Materials
• PTFE tubing, 0.063-inch ID (from the Startup kit)
• Razor blade
To connect the drip tray:
1. Cut a length of PTFE tubing sufficient to reach between the drip tray and the waste
container.
2. Connect the tubing to the white plastic fitting located under the oven of the 2410
refractometer (see Figure 2-4).
3. Insert the other end of the tubing into the waste container.
