Uni-chem Chemical Reagents Certificate Of Analysis May 2026

Uni-Chem typically follows pharmacopoeial or internationally recognized methods. Examples include:

A: Yes, but usually it is a “lot release” CoA. One CoA covers an entire production batch (e.g., 100 liters). Each bottle from that batch uses the same CoA.

A: Absolutely not. A CoA is batch-specific. Using a CoA from Batch A for Batch B constitutes data falsification in a regulated environment. uni-chem chemical reagents certificate of analysis

Chemical reagents must meet defined quality criteria to produce reliable experimental results. Uni-Chem, as a manufacturer of laboratory reagents, provides a CoA with each batch. The CoA serves as a legally binding guarantee from the manufacturer to the end-user, certifying that the product has been tested according to specified methods and meets stated limits.

Not all COAs are created equal. Uni-Chem implements three distinctive practices: Each bottle from that batch uses the same CoA

Most Uni-Chem reagent bottles now feature a QR code on the label.

Scenario: A biotech in Boston was using a discount reagent supplier for their cell culture media preparation. During a critical HPLC run to quantify a monoclonal antibody, they saw ghost peaks interfering with their analysis. Using a CoA from Batch A for Batch

The Problem: When they requested the CoA from the discount supplier, they received a generic “Certificate of Suitability” with no batch number. They could not trace the impurity.

The Fix: They switched to Uni-Chem HPLC-grade water and Acetonitrile. Upon arrival, they scanned the QR code, downloaded the batch-specific CoA, and noticed the UV absorbance specification was tighter (≤0.005 AU vs the previous 0.05 AU).

The Result: The ghost peaks disappeared. The lab manager now requires a Uni-Chem CoA to be printed and attached to every batch log sheet before use.
