TP1001 General Drug Screening kit offers the latest scientific advances in an easy-to-use, rugged and durable packaging. Our drug testing kits can be used in extreme temperature conditions and have a long shelf life. They can test any substances, including traces in the micro-gram to nanogram range, on both small and very large surfaces and can also test liquids. Each kit can be used to detect trace amounts of dangerous or illicit chemicals on persons, surfaces and clothing. This patented technology does not require the user to have direct physical contact with suspect substances and the sampler is protected from any possible combination.
