2-12 Installing the HPLC Pump
Installing the bottle holder
To install the bottle holder:
1. Position the rack along the pump’s left-hand side.
The two cutouts at the bottom inside of the rack rest must on their
corresponding positioning screws on the pump.
2. Holding the rack flush against the surface of the pump, finger tighten
the captive screw to secure the rack.
Connecting to the pump inlet
To connect the eluent tubing to the pump inlet:
1. Measure the length of 1/8-inch ETFE tubing required to connect an
eluent reservoir (mounted in the bottle holder) to an inlet manifold on
the pump.
When using high-viscosity eluents, you can possibly need to increase
reservoir height, 46 to 61 cm, above the pump’s inlet manifold.
2. Insert the ETFE tubing into the 1/8-inch diameter hole of the tubing
cutter, making sure that the tubing that extends from the metal side of
the cutter is the correct length (as determined in step 1 ).
3. Insert the razor blade into the cutter, and press down to cut the tubing.
Ensure the cut end is straight and free from burrs.
4. Slide a compression screw over one end of the tubing, followed by a
ferrule with its tapered end facing away from the tubing end (its wide
end flush with the tubing end), as shown in the figure below.
