  • Publication number: 20120070823
    Abstract: The invention relates to a method and a device for processing a biological sample. According to the invention, the processing comprises binding, washing and eluting biomolecules of the biological sample. The aim of the invention is to provide a method and a device for the automatic processing of biological samples which can have a relatively large volume and which can be further process by a microfluidic system. According to the invention, a container (1) is provided with a filter (10) and can be or is closed. A biological sample is introduced into the container. An inlet or outlet (4) for liquids is mounted downstream of the filter. In order to carry out processing, liquids that are present in the container are not only sucked off through the filter and passed on via the inlet or outlet, but liquids required for processing are also pumped into the container through the filter.

  • Publication number: 20100159532
    Abstract: The invention relates to a method and a device for performing a nucleic acid preparation and/or amplification. For the implementation of the method, a flexible tube is provided, which is always sealed below and hence at one end during the implementation of the sample preparation and/or amplification. In this tube, a biological sample is prepared and/or amplified. The use of only one tube is very economical. The tube is a disposable item which after a preparation or amplification can with its contents be disposed of environmentally correctly. Since moreover the tube has only to be filled with sample substances and reagents at a given time and manipulated, the method can also be simply and economically performed automatically.
