ABSTRACT:
An apparatus for automated loading of pipette tips (26) into storage containers or racks (28). The apparatus (21, 21a) includes a tip-orienting roller assembly (22, 22a) for orienting the tips (26) in side-by-side contact and general parallel alignment, and a spacer assembly (24, 24a) which engages the tips (26) and pushes them from the orienting assembly (22) while simultaneously spacing them at a spacing suitable for insertion into a storage container or rack (28) having spaced apart tip-receiving openings (81). In the preferred embodiment, the tip orienting assembly (22) is provided by a vibratory feeder (30) which feeds a pair of spaced apart and inclined counter-rotating rollers (36, 37), and the spacer assembly (24) pushes the tips (26) between the rollers (36, 37) and into an intermediate transfer nest assembly (27, 27a). The nest assembly (27, 27a) transfers between the roller assembly (23) and the pipette tip rack or box (28). A method for automated loading of pipette tips (26) into storage and transport containers (28) also is provided.
