Microporous plate auxiliary device

The utility model provides an auxiliary device for a microwell plate, relates to the technical field of experimental instruments, and solves the problems that in the existing liquid adding process, cells are easy to blow up, added liquid is easy to splash, a gun head touches hole walls to cause cross contamination among holes, experimental results are affected, and the experimental efficiency is high. The device comprises a base and a plurality of sample tubes, the sample tubes are arranged on the base, a marking frame is arranged at the top of the base, an auxiliary pore plate is arranged at the top of each sample tube, and a transparent thin plate is arranged at the bottom of the base. The auxiliary pore plate can accurately add reagent liquid into the through hole, pollution of a gun head is reduced, the influence of the liquid adding process on a system in the hole is reduced, and through the transparent thin plate, the situation that a green hand touches the bottom by mistake when the green hand uses the
