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
Whether you are performing a routine quality control check or preparing for a rigorous audit, knowing how to retrieve and verify an updated COA is essential. What is a Unichem Certificate of Analysis?
Regulatory bodies (FDA, EMA, ISO) require current COAs to prove that the reagents used in production meet safety standards. unichem chemical reagents certificate of analysis upd
The unique identifier for the production run. Purity Levels: The exact percentage of the active compound.
Impurities that have developed over time can cause unexpected side reactions. Once you enter the Lot number and Product
After a retest, Unichem may update the expiration or "recommended retest date" if the chemical remains stable and pure.
Using a reagent past its true stability point can ruin expensive batches of final products. Conclusion What is a Unichem Certificate of Analysis
Detailed PPM (parts per million) or percentage of impurities like heavy metals, moisture, or chlorides.
Crucial for maintaining GLP (Good Laboratory Practice). Why You May Need a COA "Update" (UPD)
