Abstract: A modular microfluidic system includes modules which are arranged next to each other in a row. Every module has a microfluidic part which rests on a contact surface of the module in a locally limited area and is forced against the contact surface by a fastening element. The microfluidic part includes a fluid channel system with fluid connections that are arranged on the top surface of the microfluidic part in edge areas relative to the adjoining microfluidic parts. The fluid connections of adjoining microfluidic parts are interlinked by respective connecting channels in a connecting part bridging the microfluidic parts, wherein the connecting part rests on the microfluidic parts in the edge areas. A clamping part rests against the lower surfaces of the adjoining microfluidic parts and is connected to the connecting part via an additional fastening element in the area between the microfluidic parts.

Abstract: The invention relates to a mixing device for mixing substances with a valve control disk and a fixed valve seat disk having at least two groups of openings each of which consists of at least three through openings. A first opening is an inlet for a substance, a second opening connects to a mixing path and a third opening bridges the mixing path. The valve control disk has a first and second recess and is arranged parallel to the valve seat disk and a flow is realized via the first recess between the first and second opening and via the second recess between the first and third opening. The first opening is superimposed by the first and second recesses and a superimposed surface area remains constant. The total superimposed surfaces of the first openings by the first recesses and by the second recesses are also constant.

Abstract: In order to be able to introduce fluid components extraneous to the system into a modular microfluidic system comprising modules arranged alongside one another which can be connected to one another with fluid connection by connecting parts comprising connecting channels with short connecting paths and good temperature controllability, a module with the following features is provided: the module has a plate-shaped microfluidic part which comprises a fluid channel system and on whose top side, in edge regions to the potentially adjacent modules of the microfluidic system has fluid connections, the fluidic connection to adjacent modules being establishable by means of the connecting parts adjacent in edge regions on the upper side, below the microfluidic part is arranged an insulation vessel which can be filled and flowed through by a temperature control fluid and is concluded at the to by the microfluidic part which serves as a lid.
