Reactor for the treatment of a sample medium
First Claim
1. A reactor comprising a reactor chamber (14, 14a, b) of a micro-mechanical construction for a sample medium containing electrical charge carriers and a generator (20) for an electrostatic field which is effective in the interior of the reaction chamber (14, 14a, b) and is cyclically reversed in its polarity and/or locally varied.

Abstract
A reactor with a reaction chamber (14), which is produced for example by etching or other micro-mechanical production processes. An agitating device (20) is formed for example by an electrical field generator (18), which acts on electrical charge carriers (21) of the sample fluid, and consequently leads to circulation or mixing of the sample fluid. As an alternative, a magnetic field generator which acts on magnetic particles in the sample fluid may also be used. The reactor permits the extensive miniaturization of test reactors for bioprocesses, since circulation of the fluid to achieve a quasi steady-state bioprocess is possible the agitating devices even under extremely confined spatial conditions.
