Record the change in performance
Note when the symptom began relative to bottle replacement, preparation, maintenance and operating changes. Preserve labels, batch numbers, expiry and storage records. Include the exact monitor fault or reading pattern rather than simply describing the reagent as defective.
Check the complete measurement context
Confirm kit identity, preparation instructions followed, bottle connections, sample delivery and the installed monitor configuration. Compare with the previous accepted batch where records exist. Do not mix suspect stock into another bottle or discard the packaging before the investigation requirements are agreed.
Keep the vessel supplied during review
Sea Clean can quote a correctly identified replacement while the evidence is reviewed. Separate the urgent operational supply decision from any quality or return assessment. Record the replacement batch and resulting instrument behaviour so the review has a meaningful before/after comparison.
Illustrative procurement scenario
Readings become unstable after a reagent change. The crew retains the packaging and preparation record, and the buyer orders a matched replacement while sample delivery and instrument condition are checked.

Frequently asked questions
Does a fault after a bottle change prove a reagent defect?
Not by itself. Sea Clean can review reagent identity and preparation alongside sample and instrument evidence, while arranging the replacement supply needed by the vessel.
