Sample sample application board that supplementary DNA electrophoresis used

The utility model discloses a sample sample application board that supplementary DNA electrophoresis used, including base and the sample application platform of setting on the base, the sample application platform is provided with a plurality of sample application signs that are the circular sunken sample application groove of matrix form range and are used for writing down sample application information, and each circular sunken sample application groove is the round platform form of inversion, and the circular diameter at its bottom surface place is lighter than the circular diameter that its up end belonged to, the sample application sign sets up the outside in the circular sunken sample application groove that is the range of matrix form. It has solved the problem that laboratory DNA sample application does not have the suitable interim carrier of DNA electrophoresis. It is through the use to circular sunken sample application groove and the base that has concave station design, has avoided at the mutual contamination or the spill that move the sample that the in -process probably caused, and can use repeatedly, has avoided the waste, use to the sample application sign makes figure, kind and the sample application order of sample distinguish more easily, has saved the run time, has improved work efficiency.
