Requirement:
As the tubing emerges from the tubing guide, thread a long, finger-tight
fitting over it. Push the tubing through the left-hand hole, to the bottom of the reservoir
bottle, and tighten the fitting.
Tips:
Follow these suggestions if you encounter difficulty threading the tubing through the
guides:
• Thread the tubing upward from the bottom hole.
• Using needle-nose pliers, make a 20° bend 10 mm from the end of the tubing. Then
rotate the tubing, as necessary, as you thread it through the guide.
4. Using a long, finger-tight fitting, connect orange, 1/16-inch, 680-mm PEEK tubing from port
2 of the LockSpray selector valve to the reference reservoir bottle or orange, 1/16-inch,
1000-mm PEEK tubing to the external reference bottle.
• To use reservoir bottle B as the reference solution, thread the tubing through tubing
guide B and secure it with a long, finger-tight fitting.
• To use an external reference bottle, push the tubing to the bottom of the reference
solution and secure the tubing at the bottle neck to prevent it from floating to the
surface during use.
