Connecting The Solvent Supply Lines To The Degasser - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

4.3.3 Connecting the Solvent Supply Lines to the Degasser

With all UltiMate 3000 system pumps, the solvent supply lines are connected to the pump
at the factory.
1. If necessary, route the solvent supply lines through the opening between the front
panel door and top cover (→ Fig. 10).

2. Tubing guides in the SRD facilitate the connection of the solvent supply lines (→ Fig.
9, page 26). Place the solvent supply line in a tubing guide, remove the blind fitting
from the associated degasser outlet if necessary (→ Fig. 9), and connect the solvent
supply line with the associated line label.
3. Locate the solvent reservoirs as close as possible to the pump. To avoid formation of
air bubbles in the reservoirs and reformation of air bubbles in the solvent, make sure
that the reservoirs are on the same level or higher as the pump.
Therefore, stack the SRD onto the pump as shown in Fig. 4 (→ page 19). The tubing
connecting the pump to the degasser should be as short as possible to avoid reformation
of air bubbles in the solvent.
Tip: If a degasser is connected to the pump but is not used (degasser turned off),
change the flow path and connect the solvent reservoirs directly to the pump,
instead.
