COD Tubes and Reagents

AccuSPEC COD Digestion Tubes use standard 16 mm tubes that have been pre-filled with digestion reagent.

The solution contains mercuric sulfate (HgSO4) to remove up to 2000 ppm of chloride interference.



COD Digestion Tubes

Simply aliquot 2 ml of sample directly to the pre-filled COD digestion tube, replace the screw cap, and mix by inverting the tube. Place the digestion tubes in the DigiPREP CUBE, or the Automated EasyPREP COD-200, set to 150 °C. Heat for 2 hours, allow samples to cool, then measure in a spectrophotometer at the appropriate wavelength. For more information on the EasyPREP COD-200, click here.
