COD vials are hot now. • Cap tubes tightly. Switch on the COD Digester and fix the temperature at 150º C and set the time at 2 hours. • Place the COD vials into a block digester at 150 C and heat for two hours. • The digester automatically switches off. Then
CODHP0 High 0 – 15,00 mg/L 43 2. Using the syringe provided, add 2.0 mL of sample to the COD vial for the low and mid range tests; add 0.2 mL of sample to the COD vial for high range tests. For best results, use a pipette to transfer samples to COD vials.
Specifications. Description. 16mm Hach vials for vials for Chemical Oxygen Demand ( COD ) determination. Results displayed as O2 mg/l. Please note a reactor is required for sample digestion. The tube tests are in high-quality glass and the reagent tubes are shipped in special packaging to protect them during transport.
2018/11/1 · High chemical oxygen demand in water indicates greater levels of oxidizable organic matter and consequently, a lower amount of Dissolved Oxygen (DO). Critical DO depletion due to organic contamination can kill off aquatic life forms.
