Novel bacteria flat plate coating pen

The novel bacterium flat plate coating pen is characterized in that the novel bacterium flat plate coating pen comprises a hollow pen shell, the pen shell comprises a first end and a second end which are open, a plugging head is arranged at the first end, and an air hole is formed in the plugging head; a porous core material is arranged in the pen shell, one end of the core material extends out of the second end to form a pen point, and the pen point is in a cuboid shape or a cone shape. The utility model has the beneficial effects that the pen shell and the core material are arranged and are matched with the pen points with different shapes, so that the flat plate scribing coating and uniform coating operation can be completed without multiple times of training, and the final bacterial colony growth quantity can be in a linear relationship from large to at least during flat plate scribing coating; during uniform coating, the space of the flat plate can be better utilized, uniform coating is realized, and the
