A container for receiving vessels for use in an automated analyzer is presented. The container comprises a wall assembly including a first wall and a second wall. The wall assembly forms a receptacle for receiving a vessel having one or more covers or lids. At least one of the first and second walls moves to provide a first open configuration for receiving the vessel and a second closed configuration. The container further comprises an actuator configured to translate the vessel from a first position after being received in the container to a second position and the wall assembly in the second closed configuration is positioned so that at least one engaging element attached to the wall assembly engages with the covers or lids of the vessel to open the covers or lids while the vessel is being translated by the actuator from the first position to the second position.

A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced. As a result of the reduced friction, the wear of the tip of the nozzle is minimized.

Reagent reservoirs and related systems and methods are disclosed. In accordance with a first implementation, an apparatus includes a system and a reagent reservoir. The system includes a reagent reservoir receptacle. The reagent reservoir is received within the reagent reservoir receptacle and has a body and a fluidic port. The body defines a storage chamber, a sipper chamber, and a fluidic sinus fluidly coupling the storage chamber and the sipper chamber. The fluidic port is fluidly coupled to the sipper chamber.
