DEVICE FOR DETERMINING AND DISPLAYING AT LEAST ONE PHYSICAL, CHEMICAL OR BIOLOGICAL PROPERTY OF A TEST LIQUID

摘要

A device for determining and displaying at least one physical, chemical or biological property of a test liquid or for detecting substances and/or organisms contained therein by reaction with at least one indicator or reactant. The indicator(s) (2.0) is/are can be accessed in or via at least one reaction chamber (1.5) provided with at least one inlet for the test fluid. Said device is embodied in the form of a deep-drawn cup-shaped element (1.1) which is sealed by a covering film (1.2). The shape and/or material properties of the reaction chamber(s) is/are preferably selected in such a way that a reset effect is created after deformation such that the original shape can be restored by creating an absorption effect until the original volume is substantially re-created.
