Abstract: The invention concerns a device for analyzing at least an analyte, comprising a container and a biochip defining together at least a section, attached to the container by a suitable adhesive. The biochip comprises a support, for example polyhedral, comprising an active face including an active surface, whereon are distributed and bound a plurality of ligands) to be analysed, at least a face opposite to the active face, and a transverse peripheral strip linking the active and opposite faces, comprising for example several edges. The invention is characterized in that the adhesive fixing the biochip to the container links, on one side the transverse strip of the biochip, practically excluding any other part, face or surface of the biochip, to the container, and the adhesive completely exposes the peripheral zone of the active face of the biochip.

Abstract: Apparatus for effecting a redially interruption of any optional duration starting from a redialling circuit having an input terminal and an output terminal, the output terminal supplying an interrupt voltage which efficiently interrupts the redialling operation, the current-voltage characteristic of the input terminal being such that current increases continously for voltage values between zero and a predetermined threshold value, and is almost zero for voltages higher than said threshold voltage, a diode connected from the output terminal to the input terminal, and the input terminal is connected to a voltage source for maintaining the voltage at the input terminal at a value higher than the threshold voltage when after the finite duration of the interruption has elapsed the output terminal no longer supplies the interrupt voltage.
