Abstract: The present invention relates to methods, devices and systems for associating consumable data with an assay consumable used in a biological assay. Provided are assay systems and associated consumables, wherein the assay system adjusts one or more steps of an assay protocol based on consumable data specific for that consumable. Various types of consumable data are described, as well as methods of using such data in the conduct of an assay by an assay system. The present invention also relates to consumables (e.g., kits and reagent containers), software, data deployable bundles, computer-readable media, loading carts, instruments, systems, and methods, for performing automated biological assays.

Abstract: In a first illustrated embodiment, the Guard comprises a split ring, having a trough formed within the inner surface thereof in which, nestably, to receive a finger-ring. The split ends of the Guard ring have a pair of arcuate, mating elements for circumscribing a finger-ring gem stone or the like, the elements being engageable together to define a circular portion. The outer surfaces of the arcuate elements are threaded to receive an internally-threaded circlet. Finally, a bulbous, hollow shield, having a circular opening, is replaceably fitted onto the circlet; the circular opening of the shield makes a frictional, sliding engagement with the circlet.
