  • Magnetically-responsive microspheres
    Patent number: 6773812
    Abstract: Microspheres are constructed using magnetic particles. Hybrid microspheres are constructed using fluorescent or luminescent microspheres and magnetic nanoparticles. Reactive moieties on the surface of the resultant particles can be used for attachment of biologically active molecules, thus allowing selective separations and analytical assays to be performed. Distinguishable subsets of microspheres can be constructed based on fluorescent intensities, and separations can be affected based on variable degree of magnetic content.
    Type: Grant

    Assignee: Luminex Corporation
    Inventors: Don J. Chandler, Michael A. Herren
  • Collection pan treatment apparatus
    Patent number: 6487867
    Abstract: An automated apparatus is provided for periodically transferring a pre-selected volume of treatment liquid to a collection pan in order to treat and prevent the clogging of the collection pan. The system includes a treatment liquid reservoir, at least one fluidic coupling, and a structure for enabling the periodic transfer of the volume of treatment liquid from the treatment liquid reservoir to the collection pan by way of the fluidic couplings, causing a treating of the collection pan.

  • Drain tube auto-servicing apparatus
    Patent number: 6442956
    Abstract: An automated apparatus is provided for sealing a low volume drain tube, pressurizing the drain tube, and unsealing the drain tube thereby causing the clearing and blowing out of any contaminants and debris present within the drain tube. The system includes a timer and controller that may be employed for causing a clearing and blowing out of the drain tube at pre-selected and regular intervals.
