  • Rod-shaped element for liquid level detection and corresponding device for liquid level detection
    Patent number: 7207219
    Abstract: A metal rod-shaped element for a liquid detecting device is essentially cylindrical and has first and second ends. In at least one length, starting from the second end, the element has an isolating coating and an electrode strip is provided which extends along a longitudinal axis of the element. The electrode strip is not electrically connected to the element and the strip comprises a high impedance material. Two flattened sections are provided where the metal of the element lies openly. In a cross sectional view the electrode strip is situated between the two flattened sections. A first contact mechanism is provided in order to establish, in the range of the first end, an electrical contact to the rod-shaped element, and a second contact mechanism is provided in order to establish, within the range of the first end, an electrical contact to the electrode strip.
    Type: Grant

  • System for releasing and isolating nucleic acids
    Patent number: 6919175
    Abstract: A procedure for the release and isolation of nucleic acids from biological compartments of a sample always uses an instrument that can hold one or more sample processsing vessels, maintain the sample processing vessels at a constant temperature, shake the sample processing vessels and separate magnetic particles by means of magnetic force. This system greatly simplifies the isolation of nucleic acids.
