As of April 2021, Hach have implemented a design changed to their 16mm COD supplied in Europe. These are beginning to hit the supply chain now so you may notice a difference in your tubes.

The main changes are as follows:

• The updated 16mm COD vials will have a round bottom to the cuvette with a larger opening simplifying handling and pipetting of your sample.
• Reagent formulations, calibration curves and test procedures remain unchanged from the predecessor vials.
• Boxes will now feature Hach part numbers suffixed with -EU. Camlab ordering part numbers remain unchanged

The following parts are affected:

• 1132932 – Low Range COD Vials (2125851)
• 1132933 – High Range COD Vials (2125951)
• 1133345 – Ultra Low Range COD Vials (2415851)
• 1133346 – Ultra High Range COD Vials (2415951)
• The two Mercury free COD vials 1133244/2345852 and 1133245/2345952 will be affected later this year.
