"Show your Colours!" – Proof by Colour Change
Suspicious substances such as pills, powders, dusts and liquids can be identified quickly and easily using wet chemical reactions with our ESA tests (ESA stands for "Eisenach Substance Analytics"). A clear colour change reveals the identity of a drug. Cocaine can additionally be detected with a wipe test on surfaces and clothing.
Substance tests based on an immunological detection method known as the lock-and-key principle – such as the nal von minden Drug Screen® Tracedetect tests – also enable the specific detection of substances traces with particularly high sensitivity. They are also suitable as specific secondary tests to confirm our chemical solid tests.
