The acceptable range or minimum/maximum thresholds required for that specific grade of chemical.

The header must include:

The validity period is tied to the product's re-test date or expiration date. Each COA includes a manufacturing date and either an expiration date or recommended re-test date. After this date, the COA is no longer valid for quality acceptance. uni-chem chemical reagents certificate of analysis

The Uni-Chem COA is a controlled, lot-specific document issued by our ISO/IEC 17025 accredited quality control laboratory. It serves as the definitive "birth certificate" for each batch of chemical reagent, providing empirical data that validates its specifications.

The most crucial piece of information for traceability. Every manufacturing run receives a unique lot number. All analytical data on the COA is tied directly to this number. After this date, the COA is no longer

Accredited laboratories (ISO 17025, GMP, GLP) must document the exact lot numbers and purity of all reagents used in testing. Audits require a readily accessible paper or digital trail of these CoAs. Prevents Cross-Contamination
