Abstract: The present invention involves a process for the isolation of nucleic acids on surfaces by means of at least the following steps: charging of a surface from a given direction with nucleic acids; immobilization of the nucleic acids on the surface; release of the immobilized nucleic acids from the surface; and removal of the released nucleic acids essentially in the direction of charging. Preferably the loading takes place from the top.

Abstract: New processes and equipment to isolate and purify nucleic acids on surfaces are provided. The invention focuses on processes which use surfaces, for example, porous membranes, on which the nucleic acids are immobilized in a simple manner from the sample containing the nucleic acids and can be released again by way of simple procedural steps, whereby the simple performance of the process according to the invention makes it possible to perform the processes specifically in a fully automatic manner. An additional aspect of the present invention focuses on binding the nucleic acids to an immobile phase, especially to a membrane, in such a way and manner, that they can be released without difficulty during an additional reaction stage from this phase and, if desired, can be used in other applications, such as restriction digestion, RT, PCR or RT-PCR, or in any of the suitable analyses or enzyme reactions mentioned in the disclosure.

Abstract: The present invention pertains to a process for the chromatographic separation of nucleic acid mixtures into their double-stranded and single-stranded nucleic acid fractions by simultaneously absorbing said nucleic acids as a whole to a mineral support, followed by separation into double-stranded and single-stranded nucleic acids by fractional elution, or by selectively absorbing double-stranded or single-stranded nucleic acid of a liquid sample to a mineral support, as well as solutions and a kit for performing the process according to the invention.

Abstract: The use of multi-well blocks with more than 10 wells is suggested for breaking down biological samples in a ball mill, wherein the process which is to be carried out provides that the biological sample, disposed in a multi-well block with more than 10 wells, is broken down in a ball mill and that following this, proteins and/or nucleic acids are isolated. With the ball mill necessary for this task, with milling containers fixed thereto in a holder (10), the milling containers are designed as uniform well blocks (16) and can be fixed in a form-locking manner into the adapted, twist-preventing holder (10).
