Abstract
The shock tube comprises a tube, a first electrode, a second electrode and a stopple, wherein the tube is internally provided with a cavity for accommodating a target liquid sample. The first electrode is arranged at one end of the tube. The second electrode is arranged in the stopple, and the outer end of the second electrode can be electrically connected with the exterior via an opening of the stopple. The stopple is internally provided with an elastic piece connected with the second electrode. The outer side of the elastic piece is connected with the stopple, and the inner side of the elastic piece is connected with the second electrode. The invention further provides a cell electroporation device where the shock tube can be placed.
