The date until which the manufacturer guarantees the reagent's stability under proper storage conditions.

Laboratories operating under strict regulatory frameworks—such as ISO 9001, ISO 17025, Good Laboratory Practice (GLP), or Good Manufacturing Practice (GMP)—are required by law to maintain strict traceability of all raw materials. Auditors will routinely ask to see the COAs matching the lot numbers written in laboratory notebooks or manufacturing logs. 3. Calibration and Instrumentation Protection

A key feature of a (or specialized reagent brands like United Chemical Technologies (UCT)) Certificate of Analysis (COA) is that it provides lot-specific analytical data rather than just general product specifications . This acts as a "report card" for the specific batch of reagent you received, ensuring its performance is predictable for sensitive laboratory work. Core Features of a Uni-Chem COA
