TN Scientific's reagent drug testing kit provides a reliable and user-friendly solution for evaluating the relative purity of drugs and substances by detecting common adulterants. Additionally, our reagent test kits are perfect for authenticating samples, ensuring safety, and delivering accurate results.


The Froehde Reagent is a reliable and easy-to-use chemical test that is ideal for identifying a range of substances. This reagent produces a distinct color change when it comes into contact with the tested substance, providing users with a quick and reliable method for detecting the presence or absence of specific substances. The Froehde Reagent is an essential tool for individuals, professionals, and hobbyists alike, ensuring safety, accurate results, and substance authentication.




The strength of the reaction remains consistent regardless of the substance amount. If multiple reactive substances are present, the resulting colors may blend, complicating interpretation. Utilizing a combination of reagents, test strips, and laboratory testing services available on our website allows for a more comprehensive analysis.
