  • Patent number: 8026068
    Abstract: This invention relates to a method for the isolation of a target nucleic acid using a material with an unmodified silica surface and subsequent amplification of the target nucleic acid in the presence of the material with an unmodified silica surface. The method is preferably carried out as an automated process preferably in a high throughput format. The method is preferably used in diagnostics.

  • Patent number: 7917313
    Abstract: The present invention relates to a method for monitoring a fluid transfer process, including the steps: providing an allowable pressure profile; detecting a pressure occurring in the course of the fluid transfer process; comparing detected pressure with the allowable pressure profile and signaling an error, if the detected pressure is not within the allowable pressure profile. The allowable pressure profile is defined by interpolation points, the interpolation points being based on a probability function representing a family of pressure courses of a plurality of fluid transfer processes. The allowable pressure profile can be divided into at least two distinct process sections, each section corresponding to a distinct process phase of the fluid transfer process. The probability function is calculated from a family of test pressure curves and reflects the statistical behavior of the pipette system.

  • Patent number: 5819508
    Abstract: Device for pulling out or twisting off caps from vessels, wherein the vessel is held, and the cap is removed by means of a cap-holding device; the cap-holding device executes both a linear movement in direction of the vessel axis as well as a rotating movement around the vessel axis. The cap-holding device advantageously has several clamping jaws that are pressed against the circumference of the cap.
