Uni-chem Chemical Reagents Certificate Of: Analysis
Most Uni-Chem reagent bottles now feature a QR code on the label.
A typical Uni-Chem CoA contains the following sections:
| Component | Description | |-----------|-------------| | Product Name & Code | 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 |
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.
The Uni-Chem COA is a controlled, lot-specific document issued by our ISO/IEC 17025 accredited quality control laboratory. It serves as the definitive "birth certificate" for each batch of chemical reagent, providing empirical data that validates its specifications.
Every Uni-Chem COA legally certifies:
This is the heart of the document. It is usually a two-column (sometimes three-column) table: Test, Specification, and Result.
| Test | Specification | Result (Example) | | :--- | :--- | :--- | | Appearance | Clear, colorless liquid | Conforms | | Assay (GC) | ≥ 99.9 % | 99.95 % | | Water Content (KF) | ≤ 0.02 % | 0.008 % | | Residue after Evaporation | ≤ 0.0005 % | 0.0001 % | | UV Absorbance (200nm) | ≤ 0.05 AU | 0.03 AU |
What Uni-Chem tests for (varies by reagent type):
A chemical is just a molecule. A Uni-Chem Chemical Reagent with its Certificate of Analysis is a certified tool for discovery.
“Trust, but verify. With Uni-Chem, verification is just a scan away.”

Product Detail Pages: Some suppliers, like Spectrum Chemical, attach the COA directly to the specific chemical’s product page under a "Resources" or "Documents" tab. What is Included in the COA?
A COA serves as a "report card" for a chemical batch, verifying it meets specific quality standards. It typically includes: How to Read a Chemical Certificate of Analysis (COA)
A Certificate of Analysis (CoA) for Uni-Chem chemical reagents is a batch-specific document that verifies the chemical identity, purity, and quality of a specific lot. It ensures that the reagent meets the required standards (e.g., ACS, AR, or USP grades) for laboratory and industrial applications. 1. Key Information in a Uni-Chem CoA
The document typically includes the following critical data points to ensure traceability and research integrity:
Product Identification: Full chemical name, molecular formula, molecular weight, and CAS Number (a unique identifier to prevent confusion with similar compounds).
Lot/Batch Information: 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:
Assay/Purity: The actual percentage of the active substance (e.g., ).
Parameters: Specific tests conducted, such as water content (Karl Fischer), trace metal analysis, or pH levels.
Specifications vs. Results: A comparison of the manufacturer's acceptable limits against the actual measured value for that specific batch.
Approval & Authentication: Signed (digitally or physically) by an authorized quality control representative, often including an electronic approval statement. 2. Common Reagent Grades Provided
Uni-Chem reagents are often categorized by purity level to match specific experimental needs: Grade Description AR / Analytical Reagent High purity (typically ) with strictly controlled impurities. Precision research, titrations, and quality control labs. ACS Grade Meets or exceeds American Chemical Society standards. Food, drug, or medicinal use; high-stringency applications. Extra Pure High-quality chemicals meeting pharmacopoeial standards. Laboratory accreditations and pharmaceutical testing. 3. How to Obtain a Uni-Chem CoA

A Uni-Chem CoA is a batch-specific document that verifies the identity, quality, and purity of a chemical reagent. Unlike a general product specification sheet—ซึ่งบอกคุณว่าผลิตภัณฑ์ควรเป็นอย่างไร—the CoA provides real-world test results for the specific lot in your hand.
Uni-Chem operates under rigorous international standards, including ISO 9001:2015
, ensuring that each CoA is generated following strict quality management protocols. Anatomy of a Uni-Chem CoA
Every Uni-Chem certificate is structured to provide immediate clarity. Here are the core sections you will typically find: 1. Product Identification & Traceability
This header section ensures you have the right material for your project: Product Name & Grade:
Clearly states the chemical and its intended use (e.g., ACS Reagent, HPLC Grade, or AR Grade). Lot/Batch Number:
The most vital piece of info for traceability. This unique ID links your bottle to the original production run and testing data. CAS Number:
The universal identifier for the chemical substance, preventing naming confusion. 2. Key Date Tracking Manufacturing Date: When the batch was synthesized or purified. Retest or Expiry Date: Crucial for inventory management. The Retest Date
indicates when the manufacturer recommends re-verifying the chemical's quality to ensure it still meets the required specifications. 3. Analytical Test Results
This is the heart of the document, typically presented in a table format: Parameters:
The specific attributes tested, such as purity (Assay), moisture content (Karl Fischer), pH, or trace metal levels. Specifications:
The "pass/fail" limits set by Uni-Chem or industry standards like the American Chemical Society (ACS). Actual Results: The numerical values obtained during laboratory testing. Explain with an Image Visualize a chemical CoA structure Create visual Why This Document Is Non-Negotiable
Certificate of Analysis (COA) คืออะไร - Apex Chemicals
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.
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.
