Patent number: 9776187Abstract: An instrument for performing highly accurate PCR employing an assembly, a heated cover, and an internal computer, is provided. The assembly is made up of a sample block, a number of Peltier thermal electric devices, and a heat sink, clamped together. A control algorithm manipulates the current supplied to thermoelectric coolers such that the dynamic thermal performance of a block can be controlled so that pre-defined thermal profiles of sample temperature can be executed. The sample temperature is calculated instead of measured using a design specific model and equations. The control software includes calibration diagnostics which permit variation in the performance of thermoelectric coolers from instrument to instrument to be compensated for such that all instruments perform identically. The block/heat sink assembly can be changed to another of the same or different design.Type: GrantFiled: August 22, 2008Date of Patent: October 3, 2017Assignee: APPLIED BIOSYSTEMS, LLCInventors: John G. Atwood, Adrian Fawcett, Keith S. Ferrara, Paul M. Hetherington, Richard W. Noreiks, Douglas E. Olsen, John R. Widomski, Charles M. Wittmer

Patent number: 9044753Abstract: An instrument for performing highly accurate PCR employing an assembly, a heated cover and an internal computer. The assembly is made up of a sample block, a number of Peltier thermal electric devices and heat sink, clamped together. The sample block temperature is changed exclusively by the thermoelectric devices controlled by the computer. The sample block is of low thermal mass and is constructed of silver. The Peltier devices are designed to provide fast temperature excursions over a wide range. The heat sink has a perimeter trench to minimize edge losses and is adjacent to a continuously variable fan. A perimeter heater is used to improve the thermal uniformity across the sample block to approximately ±0.2° C. A heated platen pushes down onto the tube caps to apply a minimum acceptable force for seating the tubes into the block, ensuring good thermal contact with the block. The force is applied about the periphery of the tube caps to prevent distortion of the caps during thermal cycling.Type: GrantFiled: January 17, 2007Date of Patent: June 2, 2015Assignee: Applied Biosystems, LLCInventors: John G.

Patent number: 8685717Abstract: An apparatus comprising an assembly and a cover. The assembly comprises a sample block configured to receive a microtiter tray having a plurality of vials, each vial comprising a cap having a surface and a perimeter. The cover comprises a platen, vertically and horizontally displaceable in relationship to the sample block, the platen having a plurality of recesses. Each recess corresponds to a respective vial and is shaped and arranged to clear the surface of its respective cap when the cover is displaced onto the sample block. The cover includes a skirt in contact with and surrounding a perimeter of the platen. The skirt is configured for mating with a perimeter of a microtiter tray when a microtiter tray is received in the sample block, and also configured such that the cover contacts a microtiter tray when a microtiter tray is received in the sample block.Type: GrantFiled: January 17, 2007Date of Patent: April 1, 2014Assignee: Applied Biosystems, LLCInventors: John G.

Publication number: 20130078713Abstract: An assembly for cycling vials of reaction mixtures through a series of temperature excursions is provided. The assembly can include a sample block for receiving the vials, a plurality of thermoelectric devices, a heat sink, and a clamping mechanism positioned to clamp the thermoelectric devices between the sample block and heatsink. The assembly can also include a thermal connector having a first end and a second end, the first end in close contact with the sample block and the second end in close contact with the heatsink to provide a thermal path between the sample block and the heatsink, the thermal connector being positioned to reduce thermal gradients across the sample block. The assembly can further include means for connecting the assembly to a computing apparatus for controlling the temperature excursions of the assembly.Type: ApplicationFiled: September 14, 2012Publication date: March 28, 2013Applicant: APPLIED BIOSYSTEMS, LLCInventors: John G. ATWOOD, Adrian FAWCETT, Keith S. FERRARA, Paul M. HETHERINGTON, Richard W. NOREIKS, Douglas E. OLSEN, John R. WIDOMSKI, Charles M. WITTMER

Patent number: 8246243Abstract: An instrument for performing highly accurate PCR employing an assembly, a heated cover, and an internal computer, is provided. The assembly is made up of a sample block, a number of Peltier thermal electric devices, and a heat sink, clamped together. A control algorithm manipulates the current supplied to thermoelectric coolers such that the dynamic thermal performance of a block can be controlled so that pre-defined thermal profiles of sample temperature can be executed. The sample temperature is calculated instead of measured using a design specific model and equations. The control software includes calibration diagnostics which permit variation in the performance of thermoelectric coolers from instrument to instrument to be compensated for such that all instruments perform identically. The block/heat sink assembly can be changed to another of the same or different design.Type: GrantFiled: January 12, 2010Date of Patent: August 21, 2012Assignee: Applied Biosystems, LLCInventors: John G.

Patent number: 6033880Abstract: Apparatus and method for performing a nucleic acid amplification reaction and preferably a polymerase chain reaction (PCR) in a reaction mixture in at least one capillary tube. Several different embodiments are disclosed. One embodiment cycles a sample through a capillary tube loop passing through two thermostatted fluid baths. Another embodiment has the capillary tube routed alternatingly between two heat exchangers to that the sample makes only one pass through the tube. Other embodiments maintain the heat exchangers stationary and translate the samples between them. Still further embodiments maintain the samples stationary and either automatically translate or rotate the heat exchangers past the samples contained within the capillary tubes to perform the thermal cycles necessary for the amplification reaction.Type: GrantFiled: February 23, 1998Date of Patent: March 7, 2000Assignee: The Perkin-Elmer CorporationInventors: Lawrence A.
