The present invention provides a system and method for the simultaneous detection of multiple analytes in a sample. The detection system includes a housing that holds a reagent carousel rotatably coupled thereto. Further included in the housing is an incubator carousel rotatably coupled thereto. The housing also includes magnetic material that is associated with the incubation carousel for assisting in separation beads from reagent and wash solution. A robot, associated with the housing is configured to manipulate at least either the reagent carousel or the incubator carousel and transfer materials therebetween. Reaction vessels hold samples and reaction vessels handlers move the reaction vessels. Sample analysis is determined by at least one laser based detector.

Devices, including a wash ring assembly, and methods are provided for the removal of excess fluid or solids from the exterior or interior of a probe used to transfer fluids, for instance, in an automated assay device. Typically, a probe is used to aspirate and dispense a sample fluid material such as whole blood or a reagent. The devices and methods provided herein are useful for removing excess fluid from the exterior or interior of the probe so as to prevent dripping and cross-contamination between samples or reagents. It is also contemplated that, utilizing the devices and methods provided herein, washing and/or drying can be performed simultaneously as the probe is in motion, aspirating a sample and/or dispensing a sample.
