Uni-chem Chemical Reagents Certificate Of Analysis _top_ Jun 2026

You can directly contact your authorized Uni-Chem supplier. Best Practices for Managing CoAs

A critical identifier that connects the document to the specific production run.

The most critical identifier. It allows you to trace the material back to its specific production run and raw materials. Analytical Results: A table comparing the specification limits (the required standards) against the actual measured values for parameters such as: Assay/Purity: Typically ≥95% for reagent grade. Impurity Limits: Levels of heavy metals, chlorides, or sulfates. Physical Properties: pH, solubility, appearance, and moisture content. Manufacturing & Expiry Dates:

I can provide specific checklists or breakdown standard impurity limits based on your needs. Share public link uni-chem chemical reagents certificate of analysis

The testing benchmarks utilized (e.g., USP, BP, or ACS guidelines). 4. Dates and Signatures Manufacturing Date: When the batch was produced.

Visit the official Uni-Chem website or the website of your local authorized Uni-Chem distributor.

For older batches (pre-2020), you may email Uni-Chem’s QA team at the address listed on their website. Provide the batch number and your lab’s credentials. You can directly contact your authorized Uni-Chem supplier

Unlike a Safety Data Sheet (SDS), which focuses on hazard communication and safety precautions, a COA focuses entirely on chemical purity and performance verification. It proves that the specific batch of reagent you received has been tested and meets predetermined specifications. Key Components of a Uni-Chem COA

: It alerts you to potential contaminants (like heavy metals) that could interfere with your specific reaction or pose a safety risk. Smart Food Safe Accessing Uni-Chem Documentation To obtain a specific CoA, you generally need the Lot Number

Detailed limits and measured values for specific contaminants, such as heavy metals, moisture content, or residue after ignition. 3. Analytical Test Methods It allows you to trace the material back

If a batch number is older or not appearing in the automated online database, contacting the Uni-Chem customer support or technical service team with the product code and lot number will allow them to retrieve the document from their manual archives. Summary of Reagent Grades Typically Found on COAs

The date the quality control team approved the batch for distribution.
