The present disclosure describes an apparatus and method of improving temperature uniformity and suppressing well plate warping. In an embodiment, the apparatus includes a barrier configured to be positioned above at least one well configured to contain a liquid sample, where a vessel includes the at least one well, where the vessel is transparent and is configured to be placed within a measurement chamber, where a light measurement apparatus includes the measurement chamber, where the light measurement apparatus is configured to measure light scattered from the liquid sample, where the barrier is configured to seal the at least one well from the measurement chamber, and a weighted lid configured to press a bottom surface of the vessel against a well plate retainer of the measurement chamber, thereby spreading heat among the at least one well and preventing the vessel from warping.

The object of the invention is to provide an automatic analysis apparatus which is capable of both sterilizing a reagent and suppressing property variations in the reagent. Provided is an automatic analysis apparatus including a reagent vessel which holds a reagent; a suction nozzle which sucks the reagent; an analysis unit which executes an analysis operation by adding a reagent sucked from the reagent vessel to a specimen via the suction nozzle; an ultraviolet ray source which sterilizes a reagent by ultraviolet irradiation; and an electrode or a substrate which supplies electric power to the ultraviolet ray source, in which a heat insulation portion is arranged between a reagent in the suction nozzle and the ultraviolet ray source and the electrode or the substrate, or, it is isolated between a reagent in the suction nozzle and the ultraviolet ray source and the electrode or the substrate.

A method for optimizing the heat transfer when performing target amplification of an assay fluid, comprising the steps of: (i) moving assay fluid through at least one channel disposed along an underside surface of a disposable cartridge of a diagnostic assay test device such that the fluid collects in a amplification region of the channel; (ii) heating the amplification region of the assay channel to heat the assay fluid; (iii) interposing a conformal material between the underside surface of a disposable cartridge and the RF heater, and (iv) applying a contact pressure between the underside surface of a disposable cartridge and the RF heater.

A method for incubating reagents, suspensions and/or biological products to a predetermined temperature for biological testing; the method comprising the steps of: a) providing a selected biological product in a receptacle and which is required to be incubated to a temperature which simulates a natural thermal environment of the biological product; b) applying controlled heating to or near the biological product using at least one laser emitting from a laser source for a time sufficient to reach a target temperature or which simulates a target temperature of the natural thermal environment in which the biological product exists.

A diagnostic assay system includes a platform configured to receive a disposable cartridge having a sample chamber for receipt of an assay fluid, and an a PCR chamber disposed in fluid communication with the sample chamber for performing target amplification of the assay fluid. A heating source is disposed adjacent a heat exchange surface disposed along at least one side of the PCR chamber and is configured to conform to the contour of the heat exchange surface to accelerate target amplification of the assay fluid. The heating source introduces heat into the assay fluid from one side of the disposable cartridge and, in one embodiment, employs a conformal material interposing the heating source and the heat exchange surface to mitigate the formation of air pockets therebetween.
