  • 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.

  • Method of magnetically separating liquid components
    Patent number: 5837144
    Abstract: Method of separating a component of a liquid from other components by immobilizing the component to suspended magnetic particles in a vessel, immersing a magnetic device into the vessel while the device is separated from the liquid by means of a protective sleeve made of a non-magnetic material. Then the non-immobilized components are removed. The invention also addresses a device suitable for implementing this method. With said method and device, resuspension is achieved in a simple and efficient manner.
