Heated reaction chamber for processing a biochip and method for controlling said reaction chamber
First Claim
1. A heated reaction chamber for processing a biochip, wherein the reaction chamber is defined at least in part by a detection window spaced apart from the biochip and a chamber wall represented by a printed circuit board on which the biochip is mounted, wherein a single heating conductor that serves as a heating device and also serves as a temperature measuring device is formed on the printed circuit board, wherein the single heating conductor is connected to a measuring and control unit capable of controlling the single heating conductor both for heating and for measuring the temperature, and wherein at least one of the printed circuit board and the detection window is sufficiently elastic to allow the biochip to be pressed into contact with the detection window.

Abstract
The invention relates to a heated reaction chamber for processing a biochip and to a method for controlling said reaction chamber. The heated reaction chamber for processing a biochip comprises a chamber wall, constituted by a flexible circuit board (10), a circuit path (10.3) being configured on the flexible circuit board (10) and being used as the heating device. The use of a flexible circuit board as the wall of a reaction chamber allows for a low thermal capacity of the reaction chamber in the area of the heating device, thereby allowing the chamber to be heated up quickly.
