Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, a PCR plate according to a preferred embodiment of the present invention includes a reaction tube 1 and a panel 2 made of PC material, the reaction tube 1 is disposed below the panel 2 and connected to the panel 2, and the panel 2 is provided with a through hole 21 corresponding to the reaction tube 1. PC (Po lycarbonate ) material has higher tolerance to the heating of constantly changing and refrigerated thermal cycle process, and panel 2 that comes out by the PC material of moulding plastics can avoid taking place to warp because of the temperature constantly changes, also can not bond on PCR heating module, makes things convenient for the staff operation to have improved work efficiency, and this no longer restricts the PCR board and uses in automatic system. In addition, panel 2 among the prior art is that the PP material is moulded plastics out, and panel 2 is softer, easily leads to panel 2 distortion when the manipulator snatchs for the PCR board can't be realized in automatic system. In this embodiment, because the PC material has higher structural strength, the manipulator presss from both sides and gets PCR board and also can not cause the deformation of panel 2, adaptation that can be better is in automatic system.

In the present embodiment, the number of the reaction tubes 1 is plural, and the through holes 21 correspond to the reaction tubes 1 one by one. The number of reaction tubes 1 matches the number of through-holes 21. Referring to fig. 1, the through holes 21 correspond to the reaction tubes 1 one to one. The through holes 21 are arranged in an array on the panel 2. The reaction tubes 1 are matched with the through holes 21 in arrangement and are also arranged in an array. The size of the orifice of the reaction tube 1 is the same as the size of the through hole 21, however, in other embodiments, the inner diameter of the orifice of the reaction tube may be slightly smaller or slightly larger than the inner diameter of the through hole.

Furthermore, one corner of the panel 2 is provided as a positioning chamfer 22. This positioning chamfer 22 can be used in an automated system, which can detect and position the PCR plate. The other corners of the panel 2 other than the positioning chamfer 22 are rounded. The setting of fillet can prevent that the corner is sharp. A skirt structure 3 made of PC material is provided around the panel 2. Skirt border structure 3's setting, the manipulator in the automatic system of can being convenient for snatchs the PCR board, but also can strengthen the structural strength of panel 2 self, prevents that panel 2 from appearing distortion. The panel 2 is further provided with a positioning notch 23, and a positioning notch 31 is arranged at the position of the skirt structure 3 corresponding to the positioning notch 23. The positioning notches 23 and the positioning notches 31 can form part of a hole which can be used to position the panel 2 for positioning the PCR plate by an automated system.

It should be noted here that the panel 2 is provided with an identification projection 24. The identification projection 24 can be easily recognized, and the identification projection 24 is a structure, not printed on the panel 2. In the prior art, the mark bulge 24 protrudes from the upper plate surface of the panel 2, so that air leakage is easy to occur during film sealing. In this embodiment, the panel 2 is a transparent panel 2, the mark protrusion 24 is disposed on the lower plate surface of the panel 2, and the mark protrusion 24 and the panel 2 are integrally formed. With this arrangement, the indication projection 24 does not protrude from the upper plate surface of the panel 2, and the indication projection 24 can be observed from the direction of the upper plate surface side.

To sum up, the embodiment of the utility model provides a PCR board, it avoids panel 2 to take place to warp because of the temperature, also can not bond on PCR heating module, has improved work efficiency, and the manipulator clamp gets the deformation that PCR board can not arouse panel 2 yet, adaptation that can be better is in automatic system.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
