Abstract: The invention relates to a method for decomposing a biological sample (9), the method having the following steps: the sample (9) is put into a container (6) which is composed of plastic, in particular, the container (6) is inserted into an adapter (2, 2a), the adapter with the closed container therein is connected to an apparatus which moves the adapter back and forth, in particular upwards, in automated fashion. This method makes it possible to decompose biological samples in automated fashion, to be precise both samples at room temperature and frozen samples. The invention also relates to an apparatus for carrying out the method, the apparatus having an adapter (2, 2a) which is predominantly composed of plastic and has sleeves (4) which are composed of metal and are intended to accommodate containers (6) which are composed of plastic, in particular.

Abstract: The invention generally provides a method for the sample preparation for a subsequent preparation, processing or analysis method of a sample containing an at least one species of nucleic acid and/or one species of protein, whereby the method comprises the following steps: A) providing a sample which contains at least one species of a nucleic acid and/or of a protein, B) contacting the sample with a fluid or solid composition to produce a fluid sample preparation, whereby the composition contains at least a nitrogenous compound, which is selected from the group consisting of a) polyamines, b) amino acids, and oligo- and polypeptides, c) nitrogenous heterocyclic compounds, including homo-oder heteropolymeres, which comprise these nitrogenous compounds, d) amines of the type R1R2NR3, whereby R1, R2 and R3 are chosen independently from one another from the group consisting of H, C1-C5-alkyl groups and aryl groups, whereby R1, R2 and R3 are not H simultaneously, e) carbonxylic acid amides, f) inorganic ammonium sa

Abstract: The present invention concerns a contamination barrier 5 that permits an efficient and reproducible processing of a high number of samples with the prevention of contamination of aqueous solutions 3 in open and/or automated systems, especially in the ppm range, in that it comprises at least one water immiscible hydrocarbon compound. In addition a method for the prevention of contamination during the processing of aqueous solutions 3 in open and/or automated systems is disclosed.
