An improved system and method for the selection and dispensing of reagents onto a target testing medium in an automated laboratory environment. The system utilizes multiple carousels rotatably-mounted upon a central turntable. The position of the central turntable, as well as the rotation of each carousel is controlled by a microprocessor-based control system. Multiple dispensers, each capable of storing and dispensing a particular reagent, are mounted about the circumference of each carousel. This configuration provides much higher reagent density than previously available. The testing medium is positioned at one or more loading stations. The control system directs the central turntable to a position from which a selected one of the carousels can be rotated so as to position a selected dispenser above the testing medium. The selected dispenser is then actuated to release a predetermined reagent onto the testing medium. The system can be configured so that multiple reagents can be dispensed, each from an associated dispenser, onto a single or multiple testing mediums. Each of these actuated dispensers being positioned over the targeted testing medium(s) positioned at one or more loading stations.

A method and a cryogenic sample positioning system are provided which include: a sample holder cassette that is vertically coupled to a carousel gear through a first shaft. Each sample holder cassette has a first degree of rotation about the first shaft. A first planet drive gear underlies and is vertically coupled to the carousel gear through a second shaft that extends from the carousel gear through the first planet drive gear. The carousel gear has a second degree of rotation about the second shaft that is different from the first degree of rotation. A planet gear that is laterally connected to a second planet drive gear is interposed between each of the carousel gear and the first planet drive gear. Each of the planet gear and the second planet drive gear selectively define the first degree of rotation, without affecting the second degree of rotation of the carousel gear.

A nucleic acid analyzer according to one or more embodiments may include a container setting part that sets a second container, a rotation drive part that rotates the container setting part by applying a driving force to a surface of the container setting part, to supply the extraction liquid injected through the injection port to the storages through the flow path by a centrifugal force. A first temperature adjustment part that adjusts a temperature of the second container provided in the container setting part, such that a nucleic acid amplification reaction occurs in the storages, and a detector that detects a nucleic acid amplification reaction which occurs in the storages with the second container provided in the container setting part interposed between the first temperature adjustment part and the detector in a vertical direction.

A switch for a conveying line for transporting a laboratory diagnostic vessel carrier is presented. The conveying line comprises a first line portion and a second line portion. The switch comprises a curved first guiding surface and a second guiding surface. The switch is moveable between a first position, in which the laboratory diagnostic vessel carrier is transportable along the curved first guiding surface from the first line portion to the second line portion, and a second position, in which the laboratory diagnostic vessel carrier is further transportable along the second guiding surface on the first line portion. A switch assembly and a conveying line are also disclosed.
