  • Patent number: 10381248
    Abstract: A system for controlling a temperature of a wafer processing substrate includes memory that stores first data indicative of first temperature responses of at least one first thermal control element. The first data corresponds to the first temperature responses as observed when a first control parameter of the at least one first thermal control element is maintained at a first predetermined first value. A first controller receives a setpoint temperature for the wafer processing substrate and maintains the first control parameter of the at least one first thermal control element at a second value based on the received setpoint temperature. A second controller retrieves the first data from the memory, calculates second data indicative of temperature non-uniformities associated with the wafer processing substrate based on the first data and the second value, and controls a plurality of second thermal control elements based on the calculated second data.

  • Patent number: 9683792
    Abstract: The present invention generally pertains to a system which utilizes floating thermal contact to enable PCR, in a thermal management device. Comprised of multiple thermal zones attached to a framework, each zone an individually actuated, isolated sub-assembly. The actuation of each zone ensures physical contact with an uneven, yet flat microfluidic chip to achieve effective, conductive heat transfer. The isolation of each zone serves to insulate the thermal zones from each other and minimize undesired heat transfer between adjacent zones, so that each zone is at a proper, uniform temperature.

  • Patent number: 8720209
    Abstract: The rapid thermal cycling of a material is targeted. A solid state heat exchanger with a first well and second well is coupled to a power module. A thermoelectric element is coupled to the first well, the second well, and the power module, is configured to transfer thermal energy from the first well to the second well when current from the power module flows through the thermoelectric element in a first direction, and is configured to transfer thermal energy from the second well to the first well when current from the power module flows through the thermoelectric element in a second direction. A controller may be coupled to the thermoelectric elements, and may switch the direction of current flowing through the thermoelectric element in response to a determination by sensors coupled to the wells that the amount of thermal energy in the wells falls below or exceeds a pre-determined threshold.

  • Patent number: 8080411
    Abstract: Disposable units in current use for performing PCR are limited by their heat block ramping rates and by the thermal diffusion delay time through the plastic wall as well as by the sample itself. This limitation has been overcome by forming a disposable plastic chip using a simple deformation process wherein one or more plastic sheets are caused, through hydrostatic pressure, to conform to the surface of a suitable mold. After a given disposable chip has been filled with liquid samples, it is brought into close contact with an array of heating blocks that seals each sample within its own chamber, allowing each sample to then be heat treated as desired.

  • Patent number: 7951345
    Abstract: The present invention provides new and useful features and mechanisms for the localization and transport of biopsy specimens. The invention having a specimen board, an absorbent material in operative engagement and in coplanar alignment with the specimen board, a compression sheet, radio opaque indicia located within the specimen board, and a flexible connection between the compression sheet and the specimen board, and an attachment device which provides for removable engagement of the specimen board and compression sheet. The apparatus further provides for a clear visualization window and operating instructions. The absorbent material is capable of adjustable movement between a first and second position, providing orthogonal positioning relative to the specimen board. As a result, the apparatus may be used to create three dimensional radiographic images allowing tissue analysis resulting in orthogonal views while maintaining original positional reference points.

  • Patent number: 7722822
    Abstract: An apparatus for processing an analyte includes a first receptacle having a first aperture, the first aperture having a first configuration; and a second receptacle having a second aperture, the second aperture having a second configuration. The first configuration and the second configuration are complementary, such that the first and second apertures engage each other at a sealing surface, whereby analyte solution within the first receptacle passes into the second receptacle substantially without leaking at the engaged first and second apertures. A method for processing an analyte comprises engaging the first and second receptacles at the sealing surface; putting a first batch of analyte solution into the first receptacle, processing the analyte solution; transferring the processed analyte solution into the second receptacle, and disengaging the second receptacle from the first receptacle.

  • Patent number: 7238517
    Abstract: An instrument for performing highly accurate PCR employing a sample block in microtiter tray format. The sample block has local balance and local symmetry. A three zone film heater controlled by a computer and ramp cooling solenoid valves also controlled by the computer for gating coolant flow through the block controls the block temperature. Constant bias cooling is used for small changes. Sample temperature is calculated instead of measured. A platen deforms plastic caps to apply a minimum acceptable threshold force for seating the tubes and thermally isolates them. A cover isolates the block. The control software includes diagnostics. An install program tests and characterizes the instrument. A new user interface is used. Disposable, multipiece plastic microtiter trays to give individual freedom to sample tubes are taught.

    Abstract: A multi-well plate is disclosed for holding chemical compounds for heating in a microwave oven. The plate is a substantially planar member having wells arranged in an array of rows and columns in its upper surface. The plate has heat reservoirs in the form of fluid filled channels or elongated solid bodies positioned lengthwise along the side portions of the plate to reduce temperature gradients among the wells across the length and width of the plate. The heat reservoirs prevent or mitigate heat loss from the wells near the side portions of the plate and ensure that the compounds in all of the wells have a uniform temperature.
