A deep well rack assembly for pipette tips and the like includes an enclosure having a plurality of openings in a top wall thereof, a plurality of wells in the enclosure extending below the top wall and openings for receiving and retaining pipette tips, and a cover for overlying the top wall of the enclosure and the wells and pipette tips. The top wall of the enclosure either has a plurality of annular depressions formed therein and surrounding the openings or a plurality of raised annular rings formed thereon and surrounding the openings. The wells are disposed within an interior cavity of the enclosure. Each well has a continuous side wall attached at an open top end to the top wall and surrounding one of the openings therein. Each well is adapated to receive a pipette tip such that the pipette tip is disposable within the well and the respective annular depression or raised annular ring of the top wall of the enclosure. The cover can be in the form of a slidable lid or one or more layers of film applied over the top wall of the enclosure and covering the openings and wells and pipette tips therein as well as the annular depressions or raised annular rings of the top wall of the enclosure.

[ We claim:] [1.] A deep well rack assembly for pipette tips, comprising:(a) an enclosure having a top wall with a plurality of openings defined in said top wall for receiving a plurality of pipette tips and a plurality of annular depressions formed in said top wall and surrounding said openings for receiving top annular flanges of the pipette tips; and(b) a plurality of wells disposed within said enclosure and extending below said top wall thereof, each of said wells including a continuous side wall having an open top end extending around a respective one of said openings in said top wall of said enclosure, each of said wells for receiving a pipette tip such that the pipette tip is disposed through said respective one of said openings in said top wall of said enclosure and within said well with the top annular flange of the pipette tip disposed in said annular depression in said top wall of said enclosures(c) said enclosure also having a bottom wall opposite from said top wall, opposite side walls and opposite end walls extending between said opposite top and bottom walls and attached to one another and to said opposite top and bottom walls so as to provide a substantially box-like configuration and together define an interior cavity, said wells being disposed within said interior cavity of said enclosure. [3.] A deep well rack assembly for pipette tips, comprising:(a) an enclosure having a top wall with a plurality of openings defined in said top wall for receiving a plurality of pipette tips and a plurality of annular depressions formed in said top wall and surrounding said openings for receiving top annular flanges of the pipette tips;(b) a plurality of wells disposed within said enclosure and extending below said top wall thereof, each of said wells including a continuous side wall having an open top end extending around a respective one of said openings in said top wall of said enclosure, each of said wells for receiving a pipette tip such that the pipette tip is disposed through said respective one of said openings in said top wall of said enclosure and within said well with the top annular flange of the pipette tip disposed in said annular depression in said top wall of said enclosure; and(c) a plurality of pipette tips each disposed through a respective one of said openings in said top wall of said enclosure and within a respective one of said wells, each of said pipette tips having a top annular flange disposed in said annular depression surrounding said respective one of said openings in said top wall of said enclosure. [14.] A deep well rack assembly for pipette tips, comprising:(a) an enclosure having a top wall with a plurality of openings defined in said top wall for receiving a plurality of pipette tips and a plurality of raised annular rings formed on said top wall and surrounding said openings and protruding above said top wall; and(b) a plurality of wells disposed within said enclosure and extending below said top wall of said enclosure, each of said wells including a continuous side wall having an open top end extending around a respective one of said openings in said top wall of said enclosure, each of said wells for receiving a pipette tip such that the pipette tip is disposed through said respective one of said openings in said top wall of said enclosure below a top surface of said raised annular ring and within said well. The assembly of claim 14 wherein said enclosure also has a bottom wall opposite from said top wall, opposite side walls and opposite end walls extending between said opposite top and bottom walls and attached to one another and to said opposite top and bottom walls so as to provide a substantially box-like configuration and together define an interior cavity, said wells being disposed within said interior cavity of said enclosure. The assembly of claim 14 wherein each of said wells also includes a bottom wall attached to and closing a bottom end of said continuous sidewall of said well. The assembly of claim 14 further comprising:a plurality of pipette tips each disposed through said respective one of said openings in said top wall of said enclosure and within a respective one of said wells, each of said pipette tips having a top end disposed below said top surface of each of said raised annular rings on said top wall of said enclosure. The assembly of claim 17 further comprising:a cover overlying a top surface of said top wall of said enclosure and said top surfaces of said raised annular rings on said top wall of said enclosure so as to cover said top wall of said enclosure and said raised annular rings thereon and said pipette tips and wells and thereby prevent cross-contamination of said pipette tips disposed in said wells. The assembly of claim 18 wherein said cover is a slidable lid mounted to said enclosure for undergoing sliding movement relative to said top wall thereof over said openings and said raised annular rings of said top wall. [28.] A deep well rack assembly for pipette tips, comprising:(a) an enclosure having a top surface and a plurality of openings defined through said top wall;(b) a plurality of wells disposed within said enclosure and attached to and extending below said top surface of said enclosure, each of said wells including a continuous side wall having an open top end extending around a respective one of said openings in said top wall of said enclosure;(c) a cover lying flush with and overlying a top surface of said top wall of said enclosure and overlying said openings and wells so as to cover said top wall of said enclosure and wells and thereby prevent cross-contamination between said wells; and(d) a plurality of pipette tips each disposed wholly within one of said wells below said top surface of said top wall and covered by said cover.
