How important is the cleanliness of the BOD bottles?
Although the cleanliness of the BOD bottles using POLYTOX is not as important as in BOD testing, it is still important. We recommend the following: • Allow to soak (around an hour) in mild soapy water (we suggest Alconox), scrub with bottlebrush (designated for BOD5 bottles only). • Allow bottles to soak in 9% Nitric acid solution or 1:1 HCl solution for about 1 hour. • Rinse bottles by allowing tap water to flow into bottles while shaking. When you notice no more bubbles appearing while you shake the bottle, rinse 2 more times. • Finally, 3 rinses with DI or sample water.
