ABSTRACT:
A biologically active substance is incorporated in a unitary body with a magnetically responsive material for carrying out diffusion testing. These may be, microbiological, immunological, serological and other biochemical examinations. The body is applied against a substrate or medium by application of an external magnetic field and a reaction region is produced at the site of the body and is measured by means of a reader. In order to insure deposit of the body on the substrate a predetermined location and corresponding reading of the reaction region at such location, the support for the substrate and the dispenser and reader are provided with suitable releasable coupling and orienting devices such that the dispenser and reader can be respectively engaged and oriented on the support in predetermined secured positions.
