Bearing device and sequencing system

Abstract

The utility model discloses a bearing device and a sequencing system. The bearing device comprises a temperature control assembly and a manifold block, the temperature control assembly comprises a heat insulation plate and a bearing table used for bearing a chip, the bearing table is installed on the heat insulation plate, the difference value between the thickness of the heat insulation plate and the reference thickness of the heat insulation plate is a first difference value, and the difference value between the thickness of the bearing table and the reference thickness of the bearing table is a second difference value; the manifold block is used for communicating the liquid path device and the chip, the manifold block is fixed in the heat insulation plate and the bearing table in a penetrating manner, and the top surface of the manifold block is lower than the top surface of the bearing table; wherein the first difference value and the second difference value are complementary, so that the height difference between the top surface of the branch block and the top surface of the bearing table meets a preset requirement. Therefore, the phenomenon that the disproportionate block cannot float due to liquid crystallization can be prevented, the flatness of the chip can be improved, the deformation degree of the chip can be reduced, the air tightness of contact between the disproportionate block and the chip can be improved, the risk of reaction liquid leakage can be reduced, and the sequencing quality of a sequencing system can be improved.
