Patent number: 6875405Abstract: A tube rack comprises a base having an array of vertical openings extending therebetween, the openings being configured and dimensioned to receive a plurality of tubes, with the upper ends of the tubes being accessible at the top surface. The base includes base sidewalls that each include a co-axial trunnion extending from the associated sidewall.Type: GrantFiled: December 9, 1999Date of Patent: April 5, 2005Assignee: Matrix Technologies CorporationInventors: Gregory Mathus, Daniel J.

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. Seguin, Victor A. Torti

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: 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: 6066297Abstract: A pipette tip with a volume capacity of at least about 1250 .mu.l that can be used with single channel or multichannel pippetors and that can be used effectively with microtiter tubes, test tubes and microtiter plates. The tip can be a single contiguous piece, typically formed of a material such as polypropylene. The total length of the pipette tip is about 4.0 inches. The tip includes a stem, a head and a midsection disposed between the stem and the head. The tip also includes a passageway that extends longitudinally through the head, the midsection and the stem.Type: GrantFiled: January 3, 1997Date of Patent: May 23, 2000Assignee: Matrix Technologies CorporationInventors: Victor A. Torti, Robert H. Zier, Jean-Paul G. Boucher

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. Laurence Keene, George P. Kalmakis

Patent number: 4896270Abstract: A computer controlled pipetting system with a hand held pipettor and a control assembly. The pipettor has a motor driven pump for aspirating and dispensing liquid through a pipette which is inserted to the pipettor. The control assembly has a keyboard for controlling operation of the pipetting system. A calibration pipette is inserted into the pipettor for establishing reference signals corresponding to a selected density and temperature of a liquid which is aspirated into the calibration pipette by the pump. The reference signals are stored in a memory and subsequently used for aspirating selected quantities of liquid into a laboratory pipette which is inserted into the pipettor in place of the calibration pipette.Type: GrantFiled: March 21, 1986Date of Patent: January 23, 1990Assignee: Matrix Technologies CorporationInventors: George P. Kalmakis, R. Laurence Keene, Gary E. Nelson, Victor A. Torti
