  • Nestable, stackable pipette rack for nestable pipette tips
    Patent number: 8168137
    Abstract: The pipette rack comprises a plate, a peripheral base and a peripheral skirt. The plate has a first surface and defines an array of tip receptacles extending therethrough in a first direction orthogonal to the first surface. The tip receptacles are contoured to provide a clearance fit at locations axially offset from one another along a part of a pipette tip. The base extends in the first direction from the plate to a distal end surface. The skirt extends in the first direction from the base, and is outwardly offset therefrom to expose the distal end surface of the base so that the distal end surface contacts the plate of a similar pipette rack when the pipette racks are stacked.
