4.3 Solvent Reservoirs
For the secure and functional positioning of the solvent reservoirs, the UltiMate 3000
system series includes Solvent Racks with and without integrated vacuum degasser
(

page 13). All Solvent Racks are shipped with solvent reservoirs and appropriate
tubing, including frit holders with filter frits.

If the UltiMate 3000 system includes an UltiMate 3000 series autosampler, you should
degas also the wash liquid on a continuous basis, for example, by using the vacuum
degasser of either the LPG-3400 or an appropriate SRD-3x00 Solvent Rack. The procedure
how to prepare and install the wash liquid lines is similar to the steps for the solvent
supply. For more information, see the
Autosampler Manual .
4.3.1 General Notes
When connecting the solvent reservoirs, observe the following general precautions:

Always install filter frits on the solvent lines. This prevents contaminants from reaching
the HPLC system that may increase wear and cause damage to the system.

Regularly check the filter frits for permeability. This is especially important when using
aqueous solvents. Aqueous solvents may contaminate the filters with algae and other
microorganisms that deposit on the filter frits. Therefore, replace the solvents at regular
intervals. Clean the reservoirs thoroughly before refilling them. Replace the filter frits as
necessary.

As a standard, filter holders with stainless steel frits are provided in the accessories kit of
the Solvent Rack. If the UltiMate 3000 system includes a biocompatible pump
(

page 14), replace the stainless steel frits with the frits provided in the accessories kit
of the biocompatible pump. Open the filter holder and remove the filter frit. When placing
the new filter frit into the bottom part, make sure that the frit is in a level position (avoid
tilting the frit).
