Abstract

There is provided a device, apparatus and methods for suspending magnetic particles retained within a container. In a particular application, magnetic particles which have become settled and even agglutinated at the lowest point, with respect to gravity, in the container, are magnetically pulled from this position, preferably to a sidewall of the container, whereby upon cessation of application of the magnetic force to the container, the particles will no longer be settled and/or agglutinated. In those containers having a fluid contained therein, the magnetic particles can then be easily suspended in the fluid. In a particular embodiment, the container is a vial retained within a cartridge for use in an automated assay apparatus.
