A tube capper and decapper and method of using the same. The tube capper includes a handheld housing that supports a one-dimensional array of spindles. Each spindle is shaped to receive a cap. A drive mechanism rotates each spindle of the one-dimensional array in unison for capping or decapping a corresponding one-dimensional array of tubes.

Handheld tube capper/decapper

A tube rack comprises a base having an array of vertical openings extending therebetween, the openings being configured and dimensioned to receive a plurality of tubes, with the upper ends of the tubes being accessible at the top surface. The base includes base sidewalls that each include a co-axial trunnion extending from the associated sidewall. The tube rack also includes a rotatable and removable cover having a front wall, a back wall and first and second sidewalls, wherein the first and second side walls each include an associated notch open on a bottom surface thereof to allow the cover to be lowered onto the base, such that each of the notches rests on its associated trunnion and may be (i) vertically raised from its closed position on the trunnions and (ii) rotated about the trunnions from its closed position to allow access to the array of openings, wherein each of the notches includes a trunnion travel surface and a ledge surface and the ledge surface engages its associated trunnion to limit rotation of the cover beyond its full cover position. Each of the openings comprises a plurality of support pads positioned within the opening to vertically support the tube within its associated opening. Each of the pads includes a chamfered concave surface that supportably engages the tube, while providing flow paths through which air may pass through the openings adjacent to the tube.

Tube rack

A pipette tip magazine used in an automated pipetting system which has a pipetting chamber with a generally U-shaped ledge. The pipette tip magazine is adapted for insertion into and removal from an operative position contained in the chamber and supported on the ledge. The magazine includes a generally rectangular plate having an undercut edge bordering an inner region. The edge is configured to be supported on the ledge, an the inner region has an array of through openings for vertically receiving and retaining pipette tips. The plate is molded from a polymeric resin reinforced with a fibrous material.

Disposable tip magazine

A test tube comprises a tube body of unitary construction including an enclosed sidewall and an integral bottom that together define a tubular container having an open top. The bottom has a concave interior surface and a planar exterior surface upon which machine readable data is encoded within a multi-layered opaque coating that is deposited onto the planar exterior surface to uniquely identify the test tube. The machine readable data is preferably an open (i.e., non-proprietary) data matrix code. This code is applied to the test tube by depositing a multi-layer coating onto the planar exterior of the tube bottom. The multi-layer coating may include a first layer of opaque material that is deposited onto the planar exterior surface, and a second layer of opaque material that is deposited onto the first layer. The machine readable code is formed in the multi-layered coating by removing portions of the second layer.

Test tube with data matrix code markings

A closure device is provided which includes a flexible cover with an array of protruding hollow caps which are formed integrally with and depend from the cover. The caps have cup shaped noses with cylindrical side walls joined to the cover by inwardly tapered intermediate wall sections. The caps form a friction fit with an array of mutually spaced receptacles, for example test tubes, deep well blocks or microwell plates.
