Abstract: A support is provided that is useful with a pipette tip holder for pipette tips. The support has a bottom member and a pair of opposed side walls that extend from the bottom member at least a distance (d). The bottom member and side walls form a cavity. Each side wall defines a slot. The slots are in a facing relationship and extend along a support plane that is parallel to and spaced from the bottom member the distance (d). The slot ends are open on one side so as to receive the pipette tip holder when slidingly inserted into the slots. The side walls preferably include an aligning member adjacent to the open slot end so that the pipette tip holder is aligned in the slots when slid in. Thus, the support supports the pipette tips and pipette tip holder during the pipette tip removal process and resists inadvertent dislodging and lifting of the tips and holder as the tips are removed.

Abstract: A pipette tip assembly is provided which includes one or more pipette tips, a tip support and a tip holder which is movable between a tip-holding and a tip-releasing position. Additionally, a pipette tip assembly is provided which includes one or more pipette tips and a tip holder which has tapered apertures therein. Methods of using such assemblies are further provided. The invention provides pipette tip assemblies that facilitate secure transport, minimal handling and convenient and user-controlled operation.
