AccuSPEC COD Digestion Tubes
AccuSPEC COD Digestion Tubes are standard 16 mm tubes that have been prefilled with the reagents
required for EPA 410.4, ISO 15705, DIN 38409 and Standard Methods 5220. Available in three ranges, the
solution contains mercuric sulfate (HgSO4) to remove up to 2000 ppm of chloride interference.
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 or other reactor, set to 150 °C, and allow to reflux
for 2 hours. Once cooled to room temperature, the samples can be measured spectrophotometrically.
