Connecting The Solvent Reservoirs - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

• When replacing solvents, make sure that the solvents are miscible. Mix immiscible
solvents with an intermediate solvent (for example, isopropanol) to replace them step-by-
step.
Tip: If the UltiMate 3000 system includes an UltiMate 3000 series autosampler,
Thermo Fisher Scientific recommends degassing the wash solution on a
continuous basis, for example, by using the degasser of an appropriate SRD.
The procedure how to prepare and install the liquid lines for the wash solution
is similar to connecting the solvent supply lines. For details, see the
Autosampler manual.

4.3.2 Connecting the Solvent Reservoirs

1. Feed the solvent supply line through the retaining guide, which holds the tubing in
place in the reservoir, and then into the open hole in the reservoir cap.
2. Verify that an appropriate frit is installed in the filter holder.

3. Slide the filter holder with filter frit onto the end of the solvent supply line.
4. If required
Cut the tubing straight if necessary. The end of the solvent supply line should be cut
straight and not deformed. Use only the original Dionex solvent supply lines.
5. Place the entire unit in the reservoir.
6. Tighten the reservoir cap hand-tight. Press the retaining guide into the hole in the
reservoir cap to hold the solvent supply line in place inside the reservoir.
