COD Tubes and Reagents

AccuSPEC COD Digestion Tubes use standard 16 mm tubes that have been prefilled with the digestion reagent. The solution contains mercuric sulfate (HgSO4) to remove up to 2000 ppm of chloride interference.


COD Digestion Tubes

Simply add 2 ml of sample to the tube, tightly replace the screw cap, and mix the contents by inverting the tube a few times. Place the vials in the DigiPREP CUBE, set to 150 °C, and allow to reflux for 2 hours. Once cooled to room temperature, the samples can be measured using a UV-visible spectrometer.

AccuSPEC COD Tubes are:

• Fully compatible with EPA 410.4 and Standard Methods 5220

Available in three ranges (150 mg/L, 1500 mg/L, 15 000 mg/L)

Compatible with standard reactors and spectrophotometers
