Beams reagent by Research Lab Fine Chem Industries is a high grade reagent. This reagent mixture is a preparation of 5 % Potassium hydroxide in 95% ethanol. This test is used to detect cannabidiol (CBD) which is an active cannabinoid identified in cannabis. To perform the test, first the sample has to be dried, purified and extracted. To this sample, the Beams reagent is added. After a short period of time, a violet colour appears. Quantity Provided: 500 ml per bottle Contains 5% KOH in 95% ethanol Suitable for testing cannabidiolBeams reagent has a variety of applications in chemical and biological sectors. This reagent is used in Beams test, one of the recognized methods for cannabis testing. Furthermore, only CBD reacts to this test and not Tetrahydrocannabinol (THC). This test can be coupled with a colorimeter to improve efficiency, and additionally, samples with a known CBD content can be tested simultaneously to produce a standard curve. This reagent is suitable for industrial synthesis of products and research applications.
