Abstract: A casing for use as a test kit that employs crushable ampoules prefilled with chemical or biological reagents, comprising a molded casing having a distinct reaction chamber, and at least one distinct cell adapted for receiving a crushable ampoule. The cell has a flexible pressing area at its outer wall for pressing and crushing the ampoule. An opening exists between the chamber and the cell that is either narrow enough, or provided with filtering means so as to allow passage of the reagent while preventing passage of glass shards from the cell to the chamber. The casing further comprises an inlet leading from the exterior of the casing into the inner space of the reaction chamber and a sampling probe, for enabling obtaining samples of material and delivery of said material through the inlet to the reaction chamber.

Abstract: Test kit and method for discriminating cocaine and its salts from substances that falsely give a positive color reaction with Scott's thiocyanate reagent. As all Scott false positive substances have lower pKa values than cocaine, or in their basic from higher pKa values than the cocaine base, they can be discriminated from cocaine by a suitable pH test of the solution. The pH indicator is preferably organic or lipophilic so that it can be dissolved in a solvent immiscible with water. The partitioning of the organic cocaine base or its salt between an organic and water phase of specific pH is used to further distinguish the test substance.
