Digital PCR instrument chip

The utility model relates to the technical field of PCR (Polymerase Chain Reaction) chips, in particular to a digital PCR instrument chip. A base layer is arranged at the bottom of a chip main body; a structural layer is arranged at the top of the base; a top layer is arranged on the top of the structural layer; the device has the beneficial effects that a solution can be introduced into a branch pipe through a liquid inlet hole, and then flows into a corresponding channel through the branch pipe, so that a sample solution can be conveniently added, and meanwhile, the solution can be prevented from being scattered; and when the solution is introduced into the branch pipes, the solution can be uniformly introduced into the three channels through the material guide blocks, so that the solution in the channels is uniformly distributed. 本实用新型涉及PCR芯片技术领域，尤其涉及一种数字PCR仪芯片；包括：芯片主体底部设置有基层；基层顶部设置有结构层；结构层顶部设置有顶层；有益效果在于：通过进液孔可将溶液通入至分支管内部，然后通过分支管可流入至对应的通道内部，从而便于对样本溶液进行添加，同时可防止溶液洒落；且当溶液通入至分支管内部时，通过导料块可将溶液均匀导入至三个所述通道内部，从而使通道
