Patent ID: 8906327

Claim:
A stackable pipette tip tray having a deck with first and second opposing longitudinal side edges each having a longitudinal dimension and first and second opposing lateral outer edges each having a lateral dimension, with the longitudinal dimension being greater than the lateral dimension, comprising: a plurality of shaft apertures, each of the plurality of shaft apertures having a first size or shape configured to receive a shaft of a pipette tip, the plurality of shaft apertures arranged into a plurality of longitudinal rows on the deck between the first and second longitudinal side edges; and a plurality of tip apertures, each of the plurality of tip apertures having a second size or shape that is different from the first size or shape and configured to receive a distal tip end of a pipette tip, and the plurality of tip apertures being arranged into a plurality of longitudinal rows on the deck with at least one of the plurality of longitudinal rows of tip apertures being located between an adjacent pair of longitudinal rows of shaft apertures, wherein an outer one of the plurality of longitudinal rows of shaft apertures adjacent the first longitudinal side edge is positioned closer to the first longitudinal side edge than an outer one of the plurality of longitudinal rows of shaft apertures adjacent the second longitudinal side edge is positioned relative to the second longitudinal side edge, wherein an outer one of the plurality of longitudinal rows of tip apertures adjacent the second longitudinal side edge is positioned closer to the second longitudinal side edge than an outer one of the plurality of longitudinal rows of tip apertures adjacent the first longitudinal side edge is positioned relative to the first longitudinal side edge, wherein a respective outer one of the plurality of shaft apertures in each of the plurality of longitudinal rows of shaft apertures adjacent the first lateral outer edge is positioned closer to the first lateral outer edge than a respective outer one of the plurality of shaft apertures adjacent the second lateral outer edge is positioned relative to the second lateral outer edge, and wherein a respective outer one of the plurality of tip apertures in each of the plurality of longitudinal rows of tip apertures adjacent the second lateral outer edge is positioned closer to the second lateral outer edge than a respective outer one of the plurality of tip apertures adjacent the first lateral outer edge is positioned relative to the first lateral outer edge.
