MICROREACTOR FOR CARRYING OUT CHEMICAL AND GENETIC TESTING Russian patent published in 2001 - IPC

FIELD: chemical engineering. SUBSTANCE: device has silicon microchip, continuous-flow reaction chamber, micro-fluid system with sublayer, electric heater unit and temperature-sensitive element connected to programmed controller forming automated temperature control system in the reaction chamber. Base and lateral chambers of the reaction chamber are created in the micro-fluid system sublayer. Another reaction chamber base is built as fluoroplastic protection layer usable for hermetically tightly attaching the reaction chamber to the microchip through an insulating layer. Hollow needle radiator is built on the microchip on the side opposite to the insulating layer. The radiator is coaxially arranged with the reaction chamber. Capillaries are created in the sublayer for supplying and discharging reaction mixture. Electric heater and temperature-sensitive element are mounted in the fluoroplastic protection layer along the reaction chamber base perimeter. The microchip and hollow needle radiator are manufacturable as a single-piece member by applying selective etching to silicon plate. Micro-fluid system sublayer is manufacturable from polymethylmetacrylate. EFFECT: improved heat discharge; lower drift; high accuracy of measurements. 3 cl, 2 dwg
