: Enter the catalog number and the specific lot number into the search fields.
Often, a condensed version or a QR code to the full CoA is provided on the reagent bottle.
The CoA alerts personnel to specific physical properties of the batch. For instance, if a batch of a hygroscopic chemical shows a higher-than-usual moisture content on the CoA, lab technicians know to handle it with stricter ambient humidity controls to avoid rapid degradation or hazardous exothermic reactions. Inventory Management
A description of the reagent's color, state (liquid/solid), and clarity. uni-chem chemical reagents certificate of analysis
Accredited laboratories (such as those holding ISO 17025 or ISO 9001 certifications) are routinely audited. Auditors require a clear documentation trail showing that every chemical used in testing was verified by a batch-specific CoA. Safety and Compatibility
How well the substance dissolves in specific solvents. 3. Specification vs. Result
Clearly states the chemical and its intended use (e.g., ACS Reagent, HPLC Grade, or AR Grade). Lot/Batch Number: : Enter the catalog number and the specific
: Instead of just stating a product "conforms" to standards, a high-quality COA lists the actual numerical results for that specific lot number, such as the exact purity percentage or concentration.
A for Uni-Chem chemical reagents is a critical quality assurance document that verifies a specific batch of chemicals meets defined purity and performance standards. Think of it as a "report card" for that specific bottle or drum, ensuring your laboratory results are accurate and reproducible. Key Components of a Uni-Chem CoA
Compare Uni-Chem's quality standards with other major suppliers. For instance, if a batch of a hygroscopic

conditions, keeping a trail of CoAs is a mandatory part of the audit process. Safety & Traceability
The core of the document is a table comparing the (the standard the chemical must meet) against the Result (what the lab actually found during testing). Assay Percentage: The exact purity level (e.g., 99.8%).
