Input the product code and lot number into the dedicated document search bar.
: A unique Lot Number that must match the label on your physical container. It also includes the Manufacturing Date and Expiry/Retest Date to manage shelf life. Analytical Results :
To find a Certificate of Analysis (CoA) for Uni-Chem reagents, you typically need to visit the supplier's website and enter specific product details. While several companies use the "Uni-Chem" name, the process for retrieving these quality documents generally follows a standard pattern across chemical manufacturers. How to Retrieve a Uni-Chem CoA
The specific attributes tested, such as purity (Assay), moisture content (Karl Fischer), pH, or trace metal levels. Specifications: uni-chem chemical reagents certificate of analysis
Even with a reputable supplier like Uni-Chem, errors in documentation can occur. If you see any of the following during an incoming goods inspection, and contact Uni-Chem support:
To read a Certificate of Analysis issued by Uni-Chem Chemical Reagents, follow these steps:
| Component | Description | |-----------|-------------| | | e.g., “Uni-Chem Sodium Chloride, AR Grade, Cat# UC-1001” | | Batch/Lot Number | Unique identifier for traceability | | Manufacturing Date | Date of production | | Retest/Expiry Date | Recommended date for re-analysis | | Appearance | Physical description (white crystalline powder, clear liquid, etc.) | | Assay (Purity) | Percentage purity (e.g., ≥99.5% by titrimetry) | | Identity Tests | Confirmation via IR, Na⁺/Cl⁻ spot tests, or retention time (HPLC) | | Impurities | Limits for chlorides, sulfates, heavy metals (as Pb), iron, etc. | | Loss on Drying | Moisture content (e.g., ≤0.5% w/w) | | Residue on Ignition | Non-volatile inorganic residue | | Solubility | Compliance with specification | | Test Methods | References to standard procedures (AOAC, USP, in-house) | | Signature/Approval | Quality control officer’s name and date |
Understanding Uni-Chem Chemical Reagents Certificate of Analysis: A Guide to Quality Assurance Physical description (e
To ensure the user has matched the correct document to the physical container, the CoA lists:
This section establishes the authenticity of the document. It features the Uni-Chem corporate branding, contact details, manufacturing facility location, and certification standards (such as ISO 9001 compliance). 2. Product Identification
In regulated laboratory environments, a chemical is only as reliable as the documentation that accompanies it. For researchers and industrial chemists using , the Certificate of Analysis (CoA) is the definitive record of a product's quality, purity, and compliance. Whether you are performing high-precision chromatography or routine quality control, understanding how to access and interpret these documents is essential for maintaining data integrity. What is a Uni-Chem Certificate of Analysis?
In conclusion, the Certificate of Analysis issued by Uni-Chem Chemical Reagents is an essential document that provides critical information about the chemical composition and properties of its products. By understanding the content and importance of the COA, customers can ensure that they receive high-quality chemical reagents that meet their requirements and are suitable for their intended use. It also includes the Manufacturing Date and Expiry/Retest
This indicates the overall purity of the reagent. For analytical reagents, this is typically or higher.
The date the chemical was synthesized, purified, or packaged.
indicates when the manufacturer recommends re-verifying the chemical's quality to ensure it still meets the required specifications. 3. Analytical Test Results
