Patent number: 9339810Abstract: A hand-held, multi-channel pipettor has an electronically controlled motor to reposition pipette tips for different center to center spacing. Each repositionable tip fitting assembly has a cam following pin that is driven by cam tracks in a motor driven roller drum. Stationary ports for the multiple aspiration cylinders are strategically placed to simplify management of flexible tubes leading to the repositionable pipette tip fitting assemblies. The pipettor has a user interface that can be operated conveniently by one hand to reposition pipette tips. It has a pipette tip ejection mechanism with a sinusoidal stripper bar.Type: GrantFiled: July 29, 2013Date of Patent: May 17, 2016Assignee: Integra Biosciences AGInventors: David Earl Butz, Gregory Mathus, Richard Cote, George P.

Patent number: 8122779Abstract: A hand-held electronic pipettor is designed particularly to be programmed and operated with one hand for the convenience of the user. It uses a capacitance touchpad control for programming, and a separate run button for the operating mode. Internal components are located so that the center of gravity of the pipettor is located within the palm of the user. Flash memory stores an empirically derived table that correlates aspiration volume to motor steps and a separate empirically derived table the correlates dispensing volumes to motor steps.Type: GrantFiled: April 13, 2009Date of Patent: February 28, 2012Assignee: Integra Biosciences Corp.Inventors: Gary E.

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. Kalmakis, R. Laurence Keene

Patent number: 6235244Abstract: A pipetting system having a plurality of tip fittings whose spacing can be simultaneously, quickly, and accurately adjusted so that the spacing between each adjacent tip fitting is substantially identical. The tip fittings are attached one to another by a linkage such as a pantographic linkage. The spacing is limited by an adjustable, slidable stop. Uniformly increasing and decreasing the spacing is accomplished by pulling and pushing a rod attached to one tip fitting.Type: GrantFiled: December 15, 1998Date of Patent: May 22, 2001Assignee: Matrix Technologies Corp.Inventors: Dave Allen, Robert H. Zier, George P. Kalmakis, Victor A. Torti, Gary E. Nelson

Patent number: 6171554Abstract: A method of identifying and arranging test tubes, which includes providing a rack having an array of wells located at the intersection of mutually perpendicular columns and rows. The columns and rows are aligned on perpendicular edges of the rack. The test tubes are positioned in the wells and then marked with indicia to correspond to the location of the respective wells.Type: GrantFiled: October 2, 1996Date of Patent: January 9, 2001Assignee: Matrix Technologies CorporationInventors: George P. Kalmakis, R. Laurence Keene

Patent number: 6123905Abstract: A pipettor including a body portion, a cylinder having an interior channel, and a filter plug disposed within the channel is disclosed. The filter plug may include a plurality of pores and may preferably be treated with a first chemical, so as to affect closure of the pores when the filter plug contacts a pipetted fluid. The pore closure helps contain leakage of the fluid into the pipettor by sealing the pipettor to additional fluid flow. The filter plug may also be treated with a second chemical to affect a change in the color of the filter plug upon contact with the pipetted fluid. The color change acts as a signal to an operator that possible contamination of the pipettor has occured. The color change and/or closure may also be affected by an aerosol generated from the pipetted fluid.Type: GrantFiled: January 17, 1997Date of Patent: September 26, 2000Assignee: Matrix Technologies CorporationInventors: Victor A. Torti, George P. Kalmakis, Gary E. Nelson

Patent number: 6019225Abstract: An improved pipette tip support rack having a honeycomb structure. The rack includes an array of interconnected sleeves, each of the sleeves being constructed to support a pipette tip therein. The sleeves are connected by bridges which form along abutting, touching surfaces thereof, or which extend between non-touching sleeves. Openings are formed between adjacent ones of said sleeve which occupy substantially all of the space between adjacent sleeves not occupied by the bridges. Inwardly extending lips on the interior of each sleeve support the enlarged portion of the pipette tip and provide a channel through which the stem extends. Interior side walls of each sleeve provide lateral support to the pipette tips. The tray may be used in conjunction with a container to provide ventilation during autoclaving. The tray snaps into the container and rests on shoulders therein. A finger tab is provided for lifting the tray out of the container.Type: GrantFiled: October 26, 1998Date of Patent: February 1, 2000Assignee: Matrix Technologies Corp.Inventors: George P. Kalmakis, Victor A. Torti, Dan Seguin, Robert H. Zier, Gary E. Nelson

Patent number: 5061449Abstract: A pipetting system having a plurality of fittings whose spacing can be simultaneously expanded from one dimension to another. Increasing the spacing is accomplished by pulling a rod, attached to one fitting, which elongates the series of fittings to a second position. In addition, there is a release mechanism for removing disposable tips attached to the fittings. The release mechanism can be operated in either position of the fittings. The mechanism is trigger actuated.Type: GrantFiled: July 25, 1989Date of Patent: October 29, 1991Assignee: Matrix Technologies, Corp.Inventors: Victor A. Torti, Gary E. Nelson, Laurence Keene, George P. Kalmakis

Patent number: 5057281Abstract: A pipetting system having a plurality of fittings whose spacing can be individually adjusted by sliding the fittings along a track. Changing the spacing is accomplished by releasing a clamping plate which secures the fittings to the track. The fittings are then slid into the desired position and reclamped. In addition, there is a stripper mechanism for removing disposable tips attached to the fittings. The release mechanism can be operated in any positioning of the fittings. The mechanism is trigger actuated.Type: GrantFiled: May 7, 1990Date of Patent: October 15, 1991Assignee: Matrix Technologies CorporationInventors: Victor A. Torti, Gary E. Nelson, R.
