A belt tensioning device for maintaining proper tension on a transfer mechanism timing belt, comprising: (a) a robotic transfer mechanism having at least one axis, a robotic head movable along said at least one axis, and a timing belt; and (b) a tensioning device operable to provide tension to said timing belt, said tensioning device comprising: i. a slide plate coupled to a tensioner housing and to an idler pulley; ii. a fixed block and threaded shaft, wherein said threaded shaft is movable relative to said fixed block; iii. a tensioner housing having a counter bore, a plunger and a compression mechanism operable to provide a force, wherein said plunger is movable relative to said counter bore and said compression mechanism; and wherein said threaded shaft is operable to drive said plunger into said counter bore, thereby compressing said compression mechanism and provide tension to said timing belt. Also disclosed is a system and method for establishing and/or maintaining proper alignment of a transfer mechanism. More specifically, an alignment system and method having one or more of: (a) a laser alignment device operable to providing precise locational coordinates for alignment of a robotic transfer mechanism relative to a holding structure; (b) an alignment tool for aligning a laser alignment device relative to robotic transfer mechanism; (c) lead in ramps to properly guide an individual specimen container into a holding well; and/or (d) a belt tensioning device for maintaining proper tension on one or more timing belts.
