Abstract

The present invention provides a polymerase chain reaction single tube structure. With the polymerase chain reaction single tube structure, a tube body and a lid forms a connection body structure, such that the lid is not easily lost; and it is ensured that the lid can conveniently cover on the tube body so as to ensure a cleanliness degree of cells inside the tube body, such that experiment data is accurate and reliable. The polymerase chain reaction single tube structure comprises a tube body and a lid, and is characterized in that both ends of a hinge are respectively connected with a tube opening of the tube body and the lid, a middle connection position of the hinge is a thin-walled structure, a round surface diameter of the lid is more than a diameter of the tube opening, the lid portion arranged on the tube opening and outwardly projecting on the tube opening is a lid brim structure, a center portion of the lid is a thin-walled round surface structure, and a guide sleeve of the lid and the inner wall of the tube opening form an interference match connection after the lid covers the tube opening.

Description

The polymerase chain reaction single tube structure

Technical field

The present invention relates to the technical field of cell culture apparatus, be specially the polymerase chain reaction single tube structure.

Background technology

Existing polymerase chain reaction single tube, its body and lid are Split type structures, in actual use, because the lid volume is little, easily lose, in case can't fast lid be placed on the body, the cell of body inside is vulnerable to pollute, and affects experimental data.

Summary of the invention

For the problems referred to above, the invention provides the polymerase chain reaction single tube structure, it is so that body, lid are conjoined structures, lid is difficult for losing, and guarantee that the lid convenient cap is loaded on body, guarantee the cleanliness factor of the cell of body inside, so that experimental data accurately and reliably.

The polymerase chain reaction single tube structure, its technical scheme is such: it comprises body, lid, it is characterized in that: the two ends of hinge connect respectively the mouth of pipe, the lid of described body, the middle junction of described hinge is thin-wall construction, the disc diameter of described lid is greater than the diameter of the described mouth of pipe, the part that stretches in the described mouth of pipe outside described lid mounts cover behind the described mouth of pipe is brim structure, the centre portions of described lid is thin-walled disc structure, and the orienting sleeve of the described lid after mounting cover is that shrink-fit connects with being connected internal wall of pipe orifice.

After using structure of the present invention, because the two ends of hinge connect respectively the mouth of pipe, the lid of described body, the middle junction of described hinge is thin-wall construction, the lid body of ining succession all the time can not come off, so that body, lid are conjoined structures, lid is difficult for losing, and guarantee that the lid convenient cap is loaded on body, guarantee the cleanliness factor of the cell of body inside, so that experimental data accurately and reliably.In addition, brim structure guarantees that lid opens conveniently; The thin-wall construction of junction in the middle of the hinge is guaranteed the stable of closure state so that can not flick behind the cap closure; The centre portions of lid is thin-walled disc structure, is convenient to puncture.

Embodiment

See Fig. 1, Fig. 2, it comprises body 1, lid 2, the two ends of hinge 3 connect respectively the mouth of pipe 4, the lid 2 of body 1, the middle junction of hinge 3 is thin-wall construction 5, the disc diameter of lid 2 is greater than the diameter of the mouth of pipe, it is brim structure 6 that lid 2 mounts cover the part that stretches in the mouth of pipe 4 outside the mouth of pipe 4 is rear, and the centre portions of lid 2 is thin-walled disc structure 7, and the inwall that the orienting sleeve 8 of the lid 2 after mounting cover is connected with the mouth of pipe is that shrink-fit connects.

Claims

1. polymerase chain reaction single tube structure, it comprises body, lid, it is characterized in that: the two ends of hinge connect respectively the mouth of pipe, the lid of described body, the middle junction of described hinge is thin-wall construction, the disc diameter of described lid is greater than the diameter of the described mouth of pipe, the part that stretches in the described mouth of pipe outside described lid mounts cover behind the described mouth of pipe is brim structure, the centre portions of described lid is thin-walled disc structure, and the orienting sleeve of the described lid after mounting cover is that shrink-fit connects with being connected internal wall of pipe orifice.
