TN Scientific's Hofmann Reagent kit is designed for chemical analysis and safety verification. This kit employs a colorimetric reaction technique, where the reagent changes color upon contact with different substances, allowing for the quick identification of a variety of chemicals. This reaction is key to verifying the presence or absence of certain compounds, making it an invaluable tool for ensuring the safety of substances in educational, research, and safety contexts. 


The kit's effectiveness lies in its straightforward approach to chemical analysis, offering both reliability and rapid results, essential for anyone needing quick verification in a range of settings.




Step 1: Place a small sample (about half the size of a grain of rice) on a non-porous surface, preferably using our test trays or tubes.


Step 2: Carefully add 1-2 drops of the reagent to the sample, ensuring no direct contact with the dropper.


Step 3: Observe any color change within 0-180 seconds and compare with the provided color chart.


For complete instructions and detailed safety data, please visit our safety data page.




Note that the reaction's intensity does not vary with the quantity of the sample. In the presence of multiple reactive agents, color results may blend, which could require additional analysis methods for clarity.
