Antwort
When testing Biochemical Oxygen Demand (BOD), very clean glassware is required to avoid any contamination.

To clean BOD bottles:

1. Use a 20 to 50% sulfuric acid solution (approximately 5 to 14 N).
2. Pour several mL of the acid into each bottle, cap, and invert to coat the inner surfaces of the bottles.
3. Rinse thoroughly with distilled water.

Use this acid rinse in the dilution bottle, fittings, tubing, glassware, and in any other labware that comes into contact with the sample.
