Abstract: A magnetic particle suspension system includes a vessel defining a chamber and an opening to the chamber, particles magnetically responsive to a magnetic field disposed in the chamber, and a suspension apparatus for controllably moving the magnetic field along a path having an engagement portion in which the magnetic field effects a magnetic response in the particles, wherein the suspension apparatus includes a motor, an arm movably driven by the motor, and a magnet supported by the arm for movement along the path, wherein the motor rotatably drives the arm about a drive axis so that the magnet travels along a circumaxial path about the drive axis.

Abstract: Apparatus and methods for providing a single-use, disposable module or manifold for testing and analysis of bioprocesses, as well as a portable and compact device which can be used with the module or manifold. A module comprising a valve, a filter or guard column, an affinity column, and a flow cell is provided with several ports for receiving tubing connections for a sample and one or more solvents, as well as one or more outlet ports for connections to one or more waste reservoirs. The flow cell may use UV light to determine a protein concentration of a sample in one particular example. The module can be connected directly or indirectly to a bioreactor containing the bioprocess and material to be sampled, and can be disposed of once a production run has been completed. In addition, manifolds are provided which can be embodied as a valve assembly, and which can comprise the same components and features as the disposable module. The manifolds and modules are compact and easy to use.
