The bottles have traditionally been made of glass, which necessary cleaning and rinsing amongst samples. A SM 5210B accredited, disposable, plastic BOD bottle is out there which removes this phase. In addition to the different dilutions of BOD samples, this procedure demands dilution h2o blanks, glucose glutamic acid (GGA) controls, and seed controls.
