Description
Technical field:
The utility model relates to the experimental article that a kind of biotechnology gene area research is used, and relates to a kind of PCR centrifuge tube in particular.
Background technology:
The communicable disease that is caused by bacterium and virus at present still is to cause a human dead important factor; The prevention and control transmissible disease at first need be understood the occurrence cause of transmissible disease, and in the research of virus spread and the clinical diagnose process, round pcr is obligato; When adopting fluorescent quantitative PCR technique to detect pathogenic agent for the childhood infection Respirovirus; Must use the PCR centrifuge tube to extract nucleic acid, PCR is extremely fine reaction, need be heated to 100 ℃ in the leaching process and keep 10 minutes; The sealing of existing P CR centrifuge tube is bad; Sample might splash out, causes the inaccurate of sample result, therefore need improve existing P CR centrifuge tube.
The utility model content:
The purpose of the utility model is the weak point to prior art, provides a kind of sealing firm, antipollution PCR centrifuge tube.
The technological solution of the utility model is following:
The PCR centrifuge tube comprises pipe shaft and the pipe close that matches with the mouth of pipe of pipe shaft, and said mouth of pipe outward flange evenly is provided with a plurality of flanges, and said pipe close is provided with the buckle that may be stuck on the flange; Said pipe close be for inserting the interior plug of the mouth of pipe, said in the plug lower rim be provided with an annular lip, be provided with the annular recesses that is complementary with annular lip at the opposite position place of the mouth of pipe.
In the technique scheme, said pipe shaft is made up of with the cone that is connected with tubular body arranged inside tubular body arranged inside.
In the technique scheme, the lower surface of said cone-shaped body is an arc surface.
In the technique scheme, said pipe shaft is connected frenulum with pipe close through one and connects.
In the technique scheme, said pipe shaft is provided with scale marks.
The beneficial effect of the utility model is:
The PCR centrifuge tube of the utility model, pipe shaft is connected frenulum with pipe close through one and connects, and connecting band can bend arbitrarily; Mouth of pipe outward flange evenly is provided with a plurality of flanges, and pipe close is provided with the buckle that may be stuck on the flange, and buckle is fastened on the flange during fastening; Pipe close is for inserting the interior plug of the mouth of pipe, and interior plug lower rim is provided with an annular lip, is provided with the annular recesses that is complementary with annular lip at the opposite position place of the mouth of pipe, and when interior plug is filled in mouth of pipe place, annular lip and annular recesses can closely cooperate; All be provided with fastening structure at the inside and outside place of the mouth of pipe like this, pipe shaft and pipe close are connected firmly, cooperate closely, pipe close can not receive the influence of ambient conditions and eject the sample that pollutes other.The utility model is safe and reliable, has guaranteed the accuracy of test structure, has avoided contamination phenomenon.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees accompanying drawing 1, and the PCR centrifuge tube comprises pipe shaft 1 and the pipe close 2 that matches with the mouth of pipe of pipe shaft, and said mouth of pipe outward flange evenly is provided with a plurality of flanges 3, and said pipe close is provided with the buckle 4 that may be stuck on the flange, and buckle is fastened on the flange during fastening; Said pipe close is for inserting the interior plug of the mouth of pipe; The plug lower rim is provided with an annular lip 5 in said, is provided with the annular recesses 6 that is complementary with annular lip at the opposite position place of the mouth of pipe, when interior plug is filled in mouth of pipe place; Through closely cooperating of annular lip and annular recesses; Pipe shaft and pipe close are connected firmly, can make the pipe close of PCR centrifuge tube eject during heat, cause sample contamination.
Said pipe shaft is made up of with the cone that is connected with tubular body arranged inside 102 tubular body arranged inside 101.
The lower surface of said cone-shaped body is an arc surface 103.
Said pipe shaft is connected frenulum 7 with pipe close through one and connects, and connecting band can bend arbitrarily.
Said pipe shaft is provided with scale marks 8, easy to use and observation.
