Abstract: Methods and apparatuses for mixing a fluid/media for an assay are disclosed herein. In an embodiment, a mixing device for an immunochemistry system includes a pipette configured to aspirate fluid and/or paramagnetic particles from or dispense fluid and/or paramagnetic particles into a cuvette, at least one nonconcentric mass configured cause the pipette to move in a mixing motion, and a control unit configured to activate the at least one nonconcentric mass while the pipette is located within the cuvette so as to mix the fluid and/or paramagnetic particles within the cuvette.

Abstract: A method, and apparatus for transferring a fluid to a sterile field includes the use of a sterile enclosure (58, 68) housing a syringe (40). The enclosure (58, 68) is made in two parts, and allows the syringe (40) to be operated while it is in the enclosure. When it is desired to pass the fluids to the sterile field, the enclosure is separated into at least two parts to allow the syringe to be removed. This removal of the syringe is done such that the user in the non-sterile field does not touch the syringe. Thus, the syringe, and fluid therein are easily transferred to the sterile field.

Abstract: A centrifuge is capable of holding a sample container in selected orientations, either during or after centrifugation, to drain supernatants between two or more chambers of the container. The draining may be gravity or centrifugal draining. This allows an automated process to subject a sample to a first physical or chemical treatment to produce a first supernatant, the first supernatant to be subjected to a second physical or chemical treatment, and a second supernatant to be separated from a desired component.
