摘要:
A method of performing a determination of an item of interest in a sample using a single structure is disclosed. A sample is provided accessible to the single structure. A first container for processing the sample is placed in a first process path on the single structure. The sample is transferred to the first container in the first process path. A reagent is added to the first container in the first process path. Contents of the first container is mixed in the first process path. The item of interest in the sample is separated from the contents of the first container in the first process path. The separated item of interest in the sample is transferred from the first container in the first process path to a second container in a second process path on the single structure. Contents of the second container is brought to a first temperature different from a temperature of the first process path in the second process path. The item of interest in the second container is detected in the second process path.

A reaction vessel with a bottom drain opening supporting a selected unpressured head of fluid by the surface tension of the fluid. A device processing zone includes a support for spaced rows of reaction vessels, passages communicating with their drain openings of supported vessels, and a pressure source for selectively draining fluid through the drain openings. Generally horizontal bar magnets are supported for selected vertical movement between the vessel rows. A dispensing head has X discharge openings selectively positionable over X selected reaction vessels. A metering pump mechanism selectively meters X a selected quantity of fluid a bulk supply (where X is at least four), and selectively pumps the metered selected quantities through the drain openings to the selected reaction vessels. Methods of drawing fluid from the vessels using the pressure source, and moving the magnets to form a pellet of analyte are also included.

摘要:
The embodiments disclosed relate to determination of an item of interest in a sample. One embodiment relates to a structure which comprises a process path. The process path comprises a process lane including a process step performance lane where a process step is performed, and a process step avoidance lane where the process step is avoided. A first prime mover is operatively connected with the process path for moving a container holding the sample along the process path. A first pipetting system is operatively associated with the process path for introducing the sample to the container. A second pipetting system is operatively associated with the process path for introducing a reagent to the container. A device is operatively connected with the process path and is selectively engagable with the container for mixing the sample and the reagent in the container. A second prime mover is operatively connected with the process path for selectively positioning the container in a selected one of the process step performance lane and the process step avoidance lane. A reader is operatively connected with the process path for determining the item of interest in the sample based upon a reaction between the sample and the reagent.
