Patent number: 8163256Abstract: An air displacement pipette has a tubular pipette tip with an upper section surrounding a locking chamber, and a body section leading from the upper section and tapering downwardly to a reduced diameter end. A tubular mounting shaft on the pipette has a distal end configured and dimensioned for axial insertion into the locking chamber of the pipette tip. Coacting surfaces on the distal end of the mounting shaft and the upper section of the pipette tip establish an axially interengaged relationship between the pipette tip and the mounting shaft in response to insertion of the distal end of the mounting shaft into the locking chamber. A sleeve is axially shiftable on the mounting shaft between a retracted position accommodating the establishment of the axially interengaged relationship, and an advanced position disrupting the axially interengaged relationship to thereby accommodate axial ejection of the pipette tip from the mounting shaft.Type: GrantFiled: July 27, 2009Date of Patent: April 24, 2012Assignee: Matrix Technologies CorporationInventors: Richard A.

Publication number: 20090104078Abstract: A pipettor includes a frame, a syringe carriage coupled to the frame and carrying at least one syringe therein, and an actuator assembly coupled to the frame and to the syringe having a first contact surface coupled to a first drive mechanism and a second contact surface coupled to a second drive mechanism, wherein the first and second contact surfaces cooperate to provide non-contact dispensing of a liquid sample from the syringe. A method of dispensing a liquid sample includes moving a first contact surface disposed beneath a head of a syringe to define a first gap therebetween, moving a second contact surface above the head into contact with the head, and using the second contact surface to drive the head into forceful contact with the first contact surface to dispense the liquid sample from the syringe in a non-contact operation.Type: ApplicationFiled: October 18, 2007Publication date: April 23, 2009Applicant: MATRIX TECHNOLOGIES CORPORATIONInventor: Daniel J.

Patent number: 7306767Abstract: A method of sealing the open mouths of an array of test tubes comprises providing a plurality of plugs with upwardly facing recesses, and a flexible carrier sheet having the same array of mutually spaced downwardly projecting pegs inserted into and frictionally retained within the recesses of respective ones of the plugs. Sealing is effected by aligning the plugs with the open mouths of the test tubes, pressing the carrier sheet towards the test tubes to seat the plugs in the open tube mouths, and peeling the carrier sheet away from the test tubes to extract the pegs from the plug recesses while allowing the plugs to remain seated in the tube mouths.Type: GrantFiled: March 15, 2005Date of Patent: December 11, 2007Assignee: Matrix Technologies CorporationInventors: Gregory Mathus, George Lyman

Patent number: 7284454Abstract: A hand-held pipette includes a piston driven by an actuator assembly contained within a housing having first and second mutually spaced non-adjustable stops. The actuator assembly is subdivided into first and second sections respectively provided with first and second contact surfaces. The actuator assembly is arranged to reciprocate between a rest position at which the first contact surface is in contact with the first stop and the second contact surface is spaced from the second stop by a control distance, and an advanced position at which the second contact surface is in contact with the second stop and the first contact surface is spaced from the first stop, with the stroke of the actuator assembly and the stroke of the piston being equal to the control distance. A motor-driven mechanism is arranged to displace one section of the actuator assembly relative to the other section, resulting in a corresponding change to both the overall length of the actuator assembly and the control distance.Type: GrantFiled: May 27, 2004Date of Patent: October 23, 2007Assignee: Matrix Technologies CorporationInventor: Richard Cote

Patent number: 6663836Abstract: A method of uniquely identifying a plurality of discrete test tubes. The method includes providing a rack having an array of wells located at the intersections of mutually perpendicular columns and rows. The rack is marked to orient the rack from top to bottom and left to right. Each well is identifiable by reference to a sequence of letters and numbers identifying its respective intersecting column and row. A plurality of test tubes are positioned in the wells. The test tubes have open tops and closed lower ends protruding through the open bottoms of the wells. Indicia are applied to the respective closed lower ends of the test tubes positioned in the wells. The application of the indicia is performed in situ and simultaneously as a single step to all of the test tubes in the wells, thereby resulting in each test tube being uniquely identified with reference to its respective well.Type: GrantFiled: January 8, 2001Date of Patent: December 16, 2003Assignee: Matrix Technologies CorporationInventors: George P.

Publication number: 20020106309Abstract: A test tube comprises a tube body of unitary construction including an enclosed sidewall and an integral bottom surface that together define a tubular container having an open top. The bottom surface 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 surface. 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.Type: ApplicationFiled: January 24, 2002Publication date: August 8, 2002Applicant: Matrix Technologies CorporationInventors: Gregory Mathus, Daniel J.
