Abstract

A sample tray carrying a two-dimensional array of sample tubes for analyses by an instrument. Tabs on the side of the tray inform the instrument as to the location of the rows of sample tubes within the tray. A short wide rack gear followed by two long thin rack gears cooperate with a pinion gear on the instrument to move the sample tray along a channel established by the instrument. The wide short rack gear serves to properly orient the tray in the instrument's channel. A C-hook at the rear of one tray can engage a T-tab at the front of a following tray to couple the two trays together. The coupling components do not extend below the upper half of the tray to assist the operator when coupling two trays together. Overhanging rack gear segments between the two coupled trays allow for their continuous propulsion by the instrument's cooperating pinion gear. The tray may take the form of a hollow shell into which fit holders providing the actual locations for the sample tubes. The holder may have a composition of plastic, cardboard, or styrofoam. Alternatively, the tray may have a nonremovable holder and operate as a solid unit.
