Assay (BSB): 190 - 230 mg/l

This lyophilized Spectroquant® BOD Standard is diluted with distilled water to prepare a standard solution of an appropriate concentration.

This standard solution is then analyzed using the Spectroquant® BOD Cell Test to check the procedure for the BOD measurement. The quantity of lyophilisate contained in each bottle of BOD Standard is sufficient to prepare 1 l of standard solution with 198 ± 40 mg/l BOD5 or 206 ± 40 mg/l BOD7.
