Assembling the system 2-27
Solvent reservoir caps help maintain sparged conditions with the reservoirs
and ensure the delivery system’s optimal performance. Each cap has three
feather-edged holes, which create a positive seal around the solvent, sparge,
and vent tubes.
Solvent reservoir caps
The caps provided with the system fit 4-liter reservoirs, which Waters
recommends. You can, however, obtain caps that fit 1-liter reservoirs.
Tip: Choose solvent reservoirs onto which caps fit snugly.
To prepare the reservoir:
1. Position the reservoir in a convenient location, preferably at the same
level as the fluid handling unit.
2. Remove protective wrapping from these nine PTFE tubes:
• Solvent A, Solvent B, Solvent C, and Solvent D
• Sparge A, Sparge B, Sparge C, and Sparge D
• Wash Inlet
3. Uncoil the tubing, and train it to the right of the fluid handling unit.
Solvent and sparge tube connections
The Startup Kit contains L-shaped tubing sections and 60-
µm eluent filters.
You can use either a section or filter on the ends of the four solvent inlet lines.
The sections weigh the ends of the inlet tubing to keep it at the bottom of the
larger solvent reservoirs but do not filter the solvent that goes to the pump.
Caution: Do not put reservoirs on top of the cabinet. Leakage can
damage the system.
