摘要： A method for performing a magnetic separation procedure that includes transporting a receptacle containing a fluid medium to a first location of a system, where the fluid medium contains both a sample material and a suspension of magnetically-responsive solid supports. At the first location, the fluid medium is exposed to a first magnetic field for a first dwell period, thereby isolating the solid supports within the receptacle, where no portion of the fluid medium is removed from the receptacle at the first location. The receptacle is then transported from the first location to a second location of the system, where the fluid medium is exposed to a second magnetic field for a second dwell period. Following the second dwell period, at least a portion of the fluid medium is removed from the receptacle. A suspension fluid is then dispensed into the receptacle, and the contents of the receptacle are agitated to suspend the solid supports within the suspension fluid.

摘要： A continuous process for performing multiple nucleic acid amplification assays, where at least a portion of a second subset of reaction mixtures are transferred to a heater while a first subset of reaction mixtures are being subjected to conditions for performing a nucleic acid amplification assay. During the process, a plurality of reaction mixtures from the first and second subsets of reaction mixtures are simultaneously subjected to conditions sufficient to perform multiple nucleic acid amplification assays in the reaction mixtures. The presence or absence of a target nucleic acid in the first subset of reaction mixtures is determined while the reaction mixtures are in the heater.

摘要： A system for separating an analyte from other components of a sample contained in a receptacle, where the system includes a receptacle holding station and a magnetic separation station. The receptacle holding station is configured to receive and hold a receptacle and includes one or more magnets positioned to apply a magnetic field to the contents of the receptacle. When present in the receptacle holding station, a receptacle remains stationary relative to the one or more magnets. The magnetic separation station includes one or more magnets and is constructed and arranged to perform a magnetic separation procedure on the contents of a receptacle transported from the receptacle holding station to the magnetic separation station by an automated receptacle transport. The magnetic separation procedure includes isolating an analyte immobilized on a magnetically-responsive solid support within the receptacle and removing other components of the sample from the receptacle. The magnetic separation station is configured to provide relative movement between the receptacle and the one or more magnets after the receptacle is transported to the magnetic separation station.

摘要： A system for separating an analyte from other components of a sample includes a receptacle holding station and a magnetic separation station. The receptacle holding station includes one or more stationary, permanent magnets positioned to apply a magnetic field to the contents of a receptacle held stationary within the receptacle holding station. The magnetic separation station includes one or more permanent magnets and is configured to perform a magnetic separation procedure on the contents of a receptacle transported from the receptacle holding station to the magnetic separation station. The magnetic separation procedure includes isolating an analyte immobilized on a magnetically-responsive solid support within the receptacle and removing other components of the sample from the receptacle. The magnetic separation station is configured to provide relative movement between the receptacle and the one or more permanent magnets after the receptacle is transported to the magnetic separation station.
