Abstract: Provided in part herein are pipette tip rack assemblies having one or more of the following features: (i) having a plurality of pipette tip receptacle plates, each plate having an array of pipette tips, stacked upon one another supported by a rack base; (ii) each plate having one or more projections from the proximal or distal surface and, optionally, orifices that oppose the projections of the next plate in the stack, and (iii) the rack base having a proximal surface with one or more orifices or projections that oppose the projections or orifices of the plate in the stack. Also provided are methods of dispensing pipette tips from pipette tip rack assemblies and manufacturing pipette tip rack assembly components.

Abstract: Disclosed here are pipette tips useful for acquiring or dispelling liquids, and include one or more design that may increase fluid delivery precision and/or accuracy, and may reduce certain repetitive motions.

Abstract: Provided herein is a pipette tip tray that includes a base and a connected pipette tip receptacle plate, where the base includes a plurality of axially-disposed base ribs disposed on two or more internal wall surfaces, the pipette receptacle plate includes a plurality of plate ribs disposed on the distal surface of the plate, and a portion of at least a subset of the plate ribs is in contact with at least a portion of an end of at least a subset of the base ribs.

Abstract: Disclosed herein are fluid handling devices that include integrated card and pipette tip devices, for use with multichannel liquid dispensing devices.

Abstract: Provided herein are fluid handling tubes having a cap that includes a sealing member having interior grooves and panels. Also provided herein are fluid handling tubes having a cap that includes (i) a sealing member having a concave surface at a distal region, and (ii) a flat proximal surface. Provided also are fluid handling tubes having a cap that includes an engagement member at an edge of the cap, where the engagement member includes a surface having curvature and a taper. Also provided herein are fluid handling tubes that include a cap comprising a tube sealing member, an anterior engagement member, and one or more channels (e.g., one or more furrows or grooves) between the sealing member and the engagement member that function as a hinge or pivot.

Abstract: Disclosed here are pipetting system devices useful for acquiring or dispelling liquids from an automated fluid dispensing device.

Abstract: Disclosed here are pipette tips useful for receiving and dispensing liquids, which include a plurality of beveled interior ribs.

Abstract: Provided in part herein are pipette tip rack assemblies having one or more of the following features: (i) having a plurality of pipette tip receptacle plates, each plate having an array of pipette tips, stacked upon one another supported by a rack base; (ii) each plate having one or more projections from the proximal or distal surface and, optionally, orifices that oppose the projections of the next plate in the stack, and (iii) the rack base having a proximal surface with one or more orifices or projections that oppose the projections or orifices of the plate in the stack. Also provided are methods of dispensing pipette tips from pipette tip rack assemblies and manufacturing pipette tip rack assembly components.

Abstract: Provided herein are pipette tip racks, and in particular, pipette tip rack plates that restrict lateral displacement of pipette tips loaded therein.

Abstract: Provided herein is a pipette tip tray that includes a base and a connected pipette tip receptacle plate, where the base includes a plurality of axially-disposed base ribs disposed on two or more internal wall surfaces, the pipette receptacle plate includes a plurality of plate ribs disposed on the distal surface of the plate, and a portion of at least a subset of the plate ribs is in contact with at least a portion of an end of at least a subset of the base ribs.
