Where to place the reagent bottle

Reagent position is very important for analysis results

The reagent bottle should be placed just below the autoBalance:

• The reagent bottle should be located as close as possible to the autoBalance, and immediately below it.
• Use the 5/3 tube (the thin one) exclusively for the reagent.
• The maximum distance from the tube to the autoBalance should be 25cm (10 in). The shorter the distance, the higher the accuracy.
• The reagent tube should have an oblique cut, to prevent it from lying flat on the bottom of the reagent bottle and creating a vacuum.
• The reagent tube should be straight and direct to the autoBalance, without elbows or connectors other than the autoBalance itself.
• The reagent bottle should be capped to prevent evaporation of the active ingredient, but not hermetically sealed, otherwise a vacuum could be produced in the bottle and consequent back pressure. It is a good idea to drill a plug with a hole slightly larger than the tube and pass the tube through it, so that enough air will enter through the hole to compensate for the drop in level.
• Change the inner tube of the reagent pump every 9 months. Keep an eye on the calibration, it should not vary too much between calibrations.
• Make sure that the reagent tubing has no bends, obstructions or cuts.
