Gene sequencing reaction device

Abstract

The invention relates to the field of gene sequencing, and discloses a gene sequencing reaction device. The gene sequencing reaction device comprises a gene sequencing reaction small chamber and a temperature measuring device, wherein the temperature measuring device comprises a temperature measuring probe; the gene sequencing reaction small chamber comprises a first substrate and a second substrate, a first groove is arranged in the first substrate, and after the first substrate attaches to the second substrate, the first groove is a reaction channel; a reagent inlet and a reagent outlet arearranged in the second substrate; the reaction channel is composed of a reaction part and a bending part, the bending part is connected with and communicates with the reaction part, and an included angle is formed between the bending part and the reaction part; a bulge is arranged on the outer surface of the second substrate, and the bulge is arranged at the position corresponding to the joint ofthe reaction part and the bending part; a temperature measuring hole is formed in the bulge, and the temperature measuring hole is used for the temperature measuring probe. The gene sequencing reaction device has the beneficial effects that the distance between a lead connected to the temperature measuring probe and a reagent inlet pipeline is increased, so that the interferences between the leadand the reagent inlet pipeline are avoided.
