Abstract
The invention relates to a reaction tube used for a polymerase chain type reactor. The reaction tube comprises a first tube body and a second tube body, wherein the upper end of the first tube body is open; the lower end of the second tube body is sealed; outer walls of the first tube body and the second tube body are rectangular; the inner wall of the first tube body is circular; the inner wall on the upper part of the second tube body is circular; the inner wall on the lower part of the second tube body is inverted cone-shaped; inner diameter of the first tube body is greater than that of the second tube body; a fixed plate is arranged at the upper end of the first tube body. According to the reaction tube used for the polymerase chain type reactor disclosed by the invention, the outer wall of the reaction tube is set to be rectangular and the tube bodies are set to be two parts with unequal inner diameters, so that sputtering of liquid in the tube bodies is effectively prevented.
Description
Technical field
The present invention relates to a kind of reaction tubes, be specifically related to a kind of reaction tubes for polymerase chain reaction instrument.
Background technology
Polymerase chain reaction technique is the technology of a kind of external rapid amplifying DNA, PCR simulates the natural reproduction process in DNA, primer according to base pairing and DNA profiling complementary in conjunction with after, under the effect of DNA polymerase, according to the principle of base pairing (A, T, C, G), from primer, start DNA chain synthetic and template DNA complementation.
The reaction tubes for polymerase chain reaction instrument of prior art, its profile mostly is circle and tube wall internal diameter is smooth, easily causes the sputter of liquid in body.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, a kind of reaction tubes for polymerase chain reaction instrument that can prevent liquid sputter is provided.
For achieving the above object, the technical solution used in the present invention is as follows.
A kind of reaction tubes for polymerase chain reaction instrument, comprise the first body and the second body, the upper end of described the first body is opening, the lower end closed of described the second body, the outer wall of described the first body and described the second body is rectangle, the inwall of described the first body is circular, the upper inside wall of described the second body is circular, the lower inner wall of described the second body is back taper, the internal diameter of described the first body is greater than the internal diameter of described the second body, and the upper end of described the first body is provided with retaining plate.
Further, the bottom of described the second body is plane.
Further, the bottom of described the second body is provided with recessed ventricumbent draw-in groove.
Further, described the first body and described the second body are one-body molded.
The invention has the beneficial effects as follows: the reaction tubes for polymerase chain reaction instrument of the present invention, by its outer wall, be set to rectangle body and be set to internal diameter two portions not etc., effectively prevented the sputter of liquid in body.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of the reaction tubes for polymerase chain reaction instrument of the present invention.
Fig. 2 is the structural representation of the second embodiment of the reaction tubes for polymerase chain reaction instrument of the present invention.
In figure, 1-the first body, 2-the second body, 3-retaining plate, 4-reverse taper portion, 5-draw-in groove.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The first embodiment of the reaction tubes for polymerase chain reaction instrument of the present invention as shown in Figure 1, comprise the first body 1 and the second body 2, the first body 1 and the second body 2 are one-body molded, the upper end of the first body 1 is opening, the lower end closed of the second body 2, the bottom of the second body 2 is plane, the outer wall of the first body 1 and the second body 2 is rectangle, the reaction tubes of rectangle is convenient to fix, the inwall of the first body 1 is circular, the upper inside wall of the second body 2 is circular, the lower inner wall of the second body 2 is reverse taper portion 4, the internal diameter of the first body 1 is greater than the internal diameter of the second body 2, the upper end of the first body 1 is provided with retaining plate 3.
By its outer wall, being set to rectangle is convenient to that it is fixed, reduced to body and rocks, body is set to two portions that internal diameter do not wait can reduce the collision that liquid resilience causes, the lower inner wall of the second body is set to back taper can make flowing fluid form eddy current, has further alleviated the sputter of liquid in body.
Fig. 2 is the structural representation of the second embodiment of the reaction tubes for polymerase chain reaction instrument of the present invention, as shown in Figure 2, be with the difference of the first embodiment, the bottom of the second body 2 is provided with recessed ventricumbent draw-in groove 5, draw-in groove is set and can further stablizes body.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the claims in the present invention.
