  • Patent number: 9776187
    Abstract: 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.

  • Patent number: 9744506
    Abstract: A receptacle having a plurality of interconnected chambers arranged to permit multiple process steps or processes to be performed independently or simultaneously. The receptacles are manufactured to separate liquid from dried reagents and to maintain the stability of the dried reagents. An immiscible liquid is included to control loading of process materials, facilitate mixing and reconstitution of dried reagents, limit evaporation, control heating of reaction materials, concentrate solid support materials to prevent clogging of fluid connections, provide minimum volumes for fluid transfers, and to prevent process materials from sticking to chamber surfaces. The receptacles can be adapted for use in systems having a processing instrument that includes an actuator system for selectively moving fluid substances between chambers and a detector. The actuator system can be arranged to concentrate an analyte in a sample. The detector can be used to detect an optical signal emitted by the contents of the receptacle.

  • Patent number: 9700888
    Abstract: Disclosed is a microfluidic cartridge that can perform highly accurate lab quality DNA tests and other amplification based tests at the point of care. The cartridge may have slanted channels that angle downward from the inlet well, where the sample is deposited, to the reaction well, where the sample will flow down to and initiate the reaction. In some examples, the cartridge may be fabricated from specific materials that enhance passive flow through the channels. Additionally, the reaction wells have an access port that allows ventilation to the reaction wells that enhances the flow of the sample from the inlet to the reaction well. The access ports allow convenient access for depositing the reaction mixture into the reaction wells after the cartridge is fabricated.

  • Patent number: 9670450
    Abstract: A cultivation apparatus and a cultivation method of a culture such as a cell or tissue. Provided are an incubator unit for accommodating a culture and a lever that penetrates through the incubator unit and can move in circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity thereof, then displacement is imparted to the culture by operating the lever. Bending force can be acted on the culture (cell construct) such as a cell or tissue, so that without any increase or decrease of a culture fluid in the incubator unit, namely, without any increase or decrease of pressure to the culture fluid, displacement required for cultivation can be imparted to the culture in the incubator unit. By curving, continuous compression and extension are generated in a direction of thickness from a concave portion to a convex portion of the curving.
