  • Fluidic system for processing a sample fluid
    Patent number: 10493445
    Abstract: The invention relates to a fluidic system comprising at least one bead chamber (311) containing a lyophilized reagent (LB) and a reaction chamber in a cartridge. In one embodiment, a series of bead chambers with different lyophilized reagents may be provided such that sample fluid can sequentially pass through them. In another embodiment, bead chambers may be located on a movable carrier, for example a rotating carousel, from which they may selectively be connected to a reaction chamber in a cartridge. In still another embodiment, the bead chamber (311) may comprise at least one flexible wall (FW) allowing for a minimization of dead volume associated with the extraction of lyophilized reagent (LB).

  • MAGNETICALLY ASSISTED PROCESSING OF A MEDIUM
    Publication number: 20150093750
    Abstract: The invention relates to a processing device (100) and a method for processing a medium in a processing chamber (121). The processing comprises the addition of magnetic particles (M) to the medium and the mixing of the medium by manipulating said magnetic particles with a time-variable magnetic field (B), particularly a partially oscillating or rotating field. The magnetic field (B) may be generated with a multipole magnetic field generator (110) comprising four subunits (111A,111B), each having a core (113A,113B) with a surrounding coil (112A,112B) and with a top surface (114A,114B), wherein all top surfaces of said subunits are preferably arranged in the same plane and wherein all cores are substantially parallel to each other.
