Abstract: A system (20) for a PCR reaction includes an array of reaction vessels mounted on a thermal mount (21). The thermal mount (21) is provided with a liquid path therein coupled to a cooling liquid input port (22), a heating liquid input port (23) and a liquid output port (24). A pump (38) is used to pump liquid from cooling liquid source (29) either along a cooling liquid path (28) to the cooling liquid input port (22), or via a heating liquid source (31), where the liquid is heated, and along a heating liquid path (30) to the heating liquid input port (23). A temperature sensor (34) measures the temperature of the thermal mount (21) and a processor (27) controls the pump, valves (26) at the input and output ports and valves (41-44) at either side of the pump (38), to control whether heating or cooling liquid is input to the thermal mount, and at what flow rate, in order to obtain the correct temperature of the thermal block (21).

Abstract: An apparatus (40) for a PCR reaction includes an array (41) of reaction vessels (42) is mounted on a thermal mount (43). The thermal mount (43) is positioned on a on a heater/cooler (45), such as a Peltier module. The array (41) is covered by a sealing film (44), which is sealed to the upper rims (49) of the vessels (42) to keep the reagents and reaction products within each vessel (42). A heated lid (50) is used to heat the underside of the sealing film to reduce condensation thereon of reagents vaporized during the reaction. The reaction vessels (42) are formed of an upper, thermally insulating part (25) and a lower, thermally conducting part (21) so as to facilitate accurate temperature control within the vessels but so as to reduce the amount of thermal energy conducted from the heated lid to the vessels, which would reduce the accuracy of the temperature control. The heated lid (50) may include a conformal layer (51) on its lower surface to conform to any variations in the configuration of the upper rims (49) of the vessels (42). The apparatus may include a thermal barrier between the lower portion (21) of the reaction vessels (42) and the heated lid (50).

Abstract: The invention provides a method and apparatus for detecting a signal of a specific spectrum emitted in the course of a chemical or biochemical reaction. The method comprises conducting the reaction in a reaction vessel, which is arranged so that light emanating from the reaction vessel is received by a detector comprising a plurality of photosensors in an array, wherein each photosensor is activated by light falling within a particular waveband range only, and where photosensors activated by light in different waveband ranges are distributed throughout the array. Output from one or more subsets of those photosensors which receive wavebands which contribute to the said specific spectrum is monitored and the output from a subset, or the relationship between the outputs of each subset are used to determine the signal in the specific spectrum.

Abstract: An apparatus for detecting spectra in light emanating from chemical or biochemical reactions occurring in at least one reaction vessel (3) of a plurality of reaction vessels is disclosed. Each reaction vessel (3) has a receptacle portion having an emitting area from which light can emanate. The apparatus may include a masking element (5) having an array of apertures (6) through which light from each reaction vessel (3) can escape. A plurality of light waveguides (7) are arranged to guide light from the apertures (6) in the masking element (5) to a light dispersing device (8) for dispersing the light from each waveguide (7) into a dispersed spectrum. A light detecting device (10) detects specific spectra in the dispersed spectra of light substantially simultaneously. In one embodiment, the apertures (6) are substantially smaller in size than the emitting area of the reaction vessel, but in another embodiment, the apertures (6) are substantially similar in size to the emitting area of the reaction vessel and the light waveguides (7) have a diameter that tapers from a first end substantially similar in diameter to the area of the top of the reaction vessel to a second end that is substantially smaller in diameter. In an alternative embodiment, the light waveguides are not used, when light from the small apertures is directed straight at the light dispersing device. In a further alternative embodiment, several light waveguides are provided for each reaction vessel, each waveguide directing light to a different detector for detecting a different specific spectrum.
