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.
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.
