Micro-droplet type digital PCR (Polymerase Chain Reaction) plate

The utility model relates to the technical field of PCR (Polymerase Chain Reaction) plates, in particular to a micro-droplet type digital PCR plate. Comprising the following steps: a plurality of reaction tubes are arranged at the top of each PCR plate; identification frames are arranged on the front side and the back side of the PCR plate; an inner groove is formed in the right side of the PCR plate; a limiting groove penetrates through the rear end of the inner groove; a limiting block is arranged on the left side of the PCR plate; the device has the beneficial effects that the limiting blocks are inserted into the inner grooves, then the PCR plates are pushed upwards, and the limiting blocks are embedded into the limiting grooves, so that the PCR plates can be spliced and fixed, and proper PCR plates can be selected for splicing according to the quantity of reaction tubes required to be used; therefore, waste caused by the fact that the whole PCR plate is subjected to an experiment under the condition that
