This kit contains one of each of the marquis, ehrlich and froehde reagents in 2 mL bottles. 2 mL provides approximately 35 drops and one drop is required per test. These three reagents all have well defined results for LSD and other hallucinogens and psychedelics, so are ideal for detecting these substances and others which may be sold in their place.
The first test to use in this pack is the ehrlich reagent. It will go purple or pink if it is exposed to an indole compound like LSD, an analogue of LSD or a tryptamine. No 0.5cm² blotter can fit an active dose of tryptamine onto it. If an LSD blotter does not change colour with ehrlich then it does not contain LSD.
Phenethylamines (like 2C-B, DOB or NBOMe) will not give a colour change with the ehrlich reagent so are detected with the froehde and marquis reagent. These reagents make all paper go slightly brown but if other colours are seen then this indicates the presence of another drug. There are a broad range of other drugs that can be added to blotter but the key point is that LSD on blotter does not change colour, so if you see a colour change with marquis or froehde it is bad.
These reagents have a shelf life of 12-18 months when stored in the fridge. All our products are shipped in high quality glass bottles to reduce degradation from light, moisture and reactions with plastics which will shorten shelf lives. After removing from the fridge make sure you let the reagent warm up and dry off before opening the lid. If you can’t store them in the fridge then keep them in a cool, dark place where the marquis reagent will last around 6 months and the froehde and ehrlich about 12 months. Includes test result guide for common compounds and full instructions.
