ABSTRACT:
An article particularly useful for Chemical Oxygen Demand (COD) tests includes an ampule, a resealing cap, and a protective sheath. The ampule includes a segment along its neck that is detachable for allowing introduction of a sample. The cap is used for resealing the neck after introduction of a sample, and the detachable segment is located at a narrow diameter portion of the neck so that the expulsion force on the cap generated by interior pressure is small. A flexible sheath is provided to protect the neck during shipment and to assist in removing the detachable segment.
