Novel PCR (polymerase chain reaction) tube

The utility model discloses a novel PCR (polymerase chain reaction) tube and particularly relates to the technical field of medical detection products. The novel PCR tube comprises a conical container tube (1), a reaction tube cap connector (2) and a reaction tube cap (4), and is characterized by further comprising a high-efficiency heat transfer layer (3) and a one-way sealing film (5), wherein the upper end of the conical container tube (1) is connected with the reaction tube cap (4) through the reaction tube cap connector (2). The novel PCR tube is characterized in that the high-efficiency heat transfer layer (3) is arranged in the middle of the conical container tube (1) and the one-way sealing film (5) is arranged in the reaction tube cap (4). The novel PCR tube is simple in structure; the high-efficiency heat transfer layer is arranged in the middle of the conventional PCR tube, so that the PCR tube can be quickly heated or cooled and the reaction efficiency is improved; and the one-way sealing film is
