In the world of laboratory research and industrial manufacturing, the precision of your results is only as good as the quality of your reagents. For professionals using , the Certificate of Analysis (COA) is the most critical document for ensuring traceability, purity, and compliance.
The Lot or Batch number is typically found on the original product label, often near the barcode or the "Use By" date. You cannot retrieve a COA using only the product name; the Lot number is mandatory for batch-specific accuracy. 2. Access the Official Unichem Portal
After a retest, Unichem may update the expiration or "recommended retest date" if the chemical remains stable and pure.
To get the most current documentation for your Unichem reagents, follow these steps: 1. Locate the Lot Number
Once you enter the Lot number and Product Code, the system will generate the most recent version of the COA. This ensures that any "UPD" (updates) to the retest dates are reflected in the file you download. The Importance of Keeping Updated Records
The term "UPD" or "update" in the context of chemical reagents usually refers to one of three scenarios:
