Location of Solvent and Waste Bottles

The DLW Option contains self priming membrane pumps. The solvent bottles
can be placed either in the Fast Wash Station Holder or on the lab bench.
The Waste bottle must be placed >30 cm below the injection valve. Make sure
that the waste liquid can flow into the waste bottle without restriction. The
waste tubing must be placed above the level of the liquid. Ideally, the tube is
fixed at the neck of the waste bottle.
Use good lab practice to avoid contaminating the wash solvents and the wash bottles.
N O T E
Avoid biological growth in pure water by either replacing it regularly or adding a few
percent of organic solvents, such as methanol or acetonitrile. Certain buffer solutions can
decompose at room temperature when exposed to light. Filtering the wash solvents before
filling into the bottle, especially if salt buffers are used, is mandatory to avoid any clogging
of the solvent paths.
