Abstract: A pipette tip system for use with a plurality of pipette tips is disclosed that includes a support card connected to a base, wherein the base comprises an interlocking structure constructed to mate with an adjacent base. This unique base can be used with the several embodiments disclosed herein.

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: 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: 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.
