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: An actuator includes an actuator housing, a screw, a nut, a rod end, a torque bar, and a bidirectional stop. The torque bar extends through the screw and is configured to rotate therewith. The torque bar has a first end and a second end. The bidirectional stop is formed on the first end of the torque bar and is disposed external to the screw. The bidirectional stop has a first side and a second side. The first side has a third dog stop formed thereon, and the second side has a fourth dog stop formed thereon. The first dog stop engages the third dog stop when the nut is in the fully extended position, and the second dog stop engages the fourth dog stop when the nut is in the fully retracted position.
