This kit consists of Marquis, Simon’s, Froehde, Morris, Ehrlich’s, Liebermann, Mecke, Mandelin, Robadope and Hofmann. These ten reagents comprise the full scope of standard reagents and allow you to test all of the most common drugs as well as numerous research chemicals. We did not include Folin in this set, because Folin is only useful for piperazine class drugs, which are fairly uncommon these days. Good for 50-75 tests. The most affordable full set of reagents available anywhere. (You’re welcome!) Instructions and color chart below.
