A pipette tip box assembly having a universal format capable of accommodating a wide variety of different pipette tip arrays. The footprint of the pipette tip box portion of the assembly is fixed to a standard (SBS) specification for microplates making the tip box compatible with the wide variety of hardware that is currently being used in automated microplate processes. The tip box portion of the pipette tip box incorporates an asymmetrical distribution of deck plate locking pins on the upper surface to retain pipette receiving deck plates having various arrays of openings thereon. The pipette tip box cover of the assembly utilizes an interlocking feature for mating pipette tip boxes within a stack of such boxes. This feature provides enhanced stability of large stacks of pipette tip boxes that are frequently required for automated processes.
