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: A pipette tip system is disclosed and includes a pipetter and a pipette tip. The pipetter has a suction lumen with an opening and an ejection bar that slides relative to the suction lumen. The pipette tip has a distal end with a distal end opening and a proximal end with a rim that defines a proximal opening adapted to receive the pipetter. The pipette tip also has a central lumen extending from the proximal end opening to the distal end opening and a pipette tip wall extending from the rim forming the central lumen. The pipette wall comprises a low-force stretch region with a plurality of thinning channels to allow for the stretching of the pipette tip wall.

Abstract: A pipetter is disclosed that has a suction lumen with an opening and an ejection bar that slides relative to the suction lumen. The pipette tip has a distal end opening and a proximal end with a rim. The pipette tip has a pipette wall with a low-force stretch region with a plurality of thinning channels. The system comprises at least three configurations: an insertion configuration, wherein (1) the suction lumen is inserted into the proximal opening, and (2) the ejection bar does not abut the rim; a sealed/installed configuration, wherein (1) the suction lumen forms a liquid-tight seal between the suction lumen and the pipette wall, and (2) the ejection bar abuts the rim, preventing further insertion of the suction lumen (95); and an ejection configuration, wherein (1) the ejection bar is slid towards the rim, and (2) the ejection bar dislodges the pipette tip from the suction lumen.

Abstract: A pipette tip system for use with a plurality of pipette tips is disclosed that includes a support card and a support card lid. The support card includes an array of pipette tip receiver openings arranged in a N×M array, wherein the N is less than M. The support card further has a short-side card rail edge on an edge of the support card along the N side of the array, and a long-side card rail edge on an edge of the support card along the M side of the array. The support card lid includes a long-side lid rail edge extending from a support card first surface, which is adapted to slidably mate with the long-side card rail edge, and a short-side lid rail edge extending from a support card second surface, which is adapted to slidably mate with the short-side card rail edge.

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: A face shield for covering the eyes, nose and mouth of a user is disclosed. The face shield includes a face shield body that has a transparent surface having a first side edge, a second side edge, and a top edge. The first and second side edges include a first and a second anchor/barb, respectively, both of which define a line. A spacer is attached at or near the line, and the spacer extends away from the face shield body. An elastic strap with a first slot and a second slot receives the first and second anchor/barbs. When the user wears the face shield, the elastic strap is in a stretched configuration that pulls on the first and second anchor/barbs, and in this configuration the first slot is detachably affixed to the first anchor/barb, and the second slot is detachably affixed to the second anchor/barb.

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: The system includes a pipette tip with a proximal end that has a rim. The rim defines a proximal opening adapted to receive a pipetter, and the rim includes a rim conical edge. The system also has a support card with a top surface, a pipette tip receiver opening within the top surface, the opening adapted to receive the pipette tip and having a receiver opening conical edge. The rim conical edge and the receiver opening conical edge are constructed such that when the pipette tip is disposed of in the pipette tip receiver opening, the rim conical edge abuts the receiver opening conical edge, and the top surface is flush with or nearly flush with the rim.
