Abstract: An automated pipetting system includes a pipettor. The pipettor includes a pipetting channel, a first plunger mechanism operable to change a pressure in the pipetting channel to aspirate or dispense a liquid, and a second plunger mechanism operable to change the pressure in the pipetting channel to aspirate or dispense the liquid.

Abstract: A device for the reversible immobilization of biomolecules includes a container which can be filled with a liquid containing biomolecules and has an opening and a valve. The valve can be opened and closed by a closing mechanism for the controllable drainage of the liquid. Magnetic particles, to which the biomolecules can be immobilized can be arranged freely movable in the container. A magnet for fixing the magnetic particles in the container is arranged at the container, and the liquid can be removed from the container through the opening in the open state of the valve.

Abstract: An optical measuring system and a method for gas detection, the optical measuring system including a light emitter and at least one light detector arranged in at least one housing, wherein the light emitter emits a modulated main light beam with a mean wave length ?0 with a modulation span ??. At least one opto-mechanical component, e.g. a housing window including optically effective boundary surfaces, is arranged between the light emitter and the light detector and causes scatter light beams which interfere with the main light beam so that self-mixing occurs and/or etalons are caused. According to the invention the at least one opto-mechanical component is arranged relative to the light emitter and/or the light detector at an optimized distance L which is a function of the wave length ?0 and the modulation span ?? of the main light beam.

Abstract: The invention relates to an optical imaging system (20) comprising an illumination unit (23), a detection unit (24) and a measurement chamber (21) for receiving a subject to be examined, wherein the illumination unit (23) is arranged such in relation to the measurement chamber (21) that it can illuminate a subject placed inside the measurement chamber (21), and wherein the measurement chamber (21) is provided with several fins (31, 31?) for preventing stray light from reaching the detection unit (24), the several fins (31, 31?) being arranged in such a way that at least some of the fins (31, 31?) are in the field of view of the detection unit (24) with the fins (31, 31?) being orientated such that the surfaces (31.1, 31.1?) of the fins that are subjected to illumination by stray light are not visible to the detection unit (24).
