Abstract: Disclosed is a filtering method for isolating a substance from a sample. The method includes: providing a filter module having a sample inlet, a sample outlet, and a filter covering the sample outlet; introducing, via a sample inlet a first quantity of the sample into the filter module; conducting the sample from the sample inlet through the filter and the sample outlet by applying a pressure difference between a side of the filter facing the sample inlet and a side of the filter facing away from the sample inlet; measuring the pressure difference and/or a volumetric flow through the filter; comparing the measurement values to a predefined reference value; and ending the method if successively detected measurement values lie within a predefined range of values around the reference value. Disclosed also is a device with which the method can be carried out.

Abstract: A temperature-control device for receiving a reaction vessel having a heat-insulated interior space and which is covered by a lid. The reaction vessel has a hollow body and a cap, this hollow body being closed on one side by a base. The base contacts a heatable heating block in order to heat a sample located in the reaction vessel. The hollow body is surrounded by a heatable heating body which communicates with the lid via a heat-conducting contact region so that the heating body heats the hollow body directly and heats the cap indirectly via the lid.

Abstract: The invention relates to a mobile device system, comprising a hand-held device and a test kit for the mobile isolation of nucleic acids. The hand-held device comprises at least one sample block for inserting sample containers, a sample block holder with boreholes or recesses for accommodating the sample blocks, a device base with electronic control units for the sample blocks, a voltage source and a connection to the sample block holder, as well as a test kit for the isolation of nucleic acids. The hand-held device is characterized in that the sample blocks can be removed from the sample block holder and the sample block holder can be removed from the device base.
