Beneficial effects of the present invention:

1. when centrifuge tube covers, the cover rim of pipe lid is fastened in the V-arrangement space that mouth of pipe inside and outside wall is formed, engaging area is big, make engaging tightr, extraneous antibacterial or pollutant enter in pipe and need the binding face through mouth of pipe outer wall and cover rim outer wall, it is then passed through internal wall of pipe orifice and the binding face of cover rim inwall, this process is difficult, and therefore the present invention effectively prevent the pollution of material in pipe, also effectively prevents managing interior material and overflows along cover rim.

2. hollow between cover rim inwall and cover rim outer wall, cover rim inwall and cover rim outer wall is enable to produce slight deformation when covering, the strength of deformation can make cover rim and the engaging of mouth of pipe inside and outside wall tightr, realizing preventing the pollution managing interior material further, more efficient preventing manages interior material along cover rim spilling.

3. the setting of spanner, it is simple to the switch of pipe lid.

4. pipe lid and body are linked together by soft folded structure so that pipe lid also links together with body after opening all the time, and pipe lid is not easily lost, obscured.

5. current centrifuge tube is all enter in pipe by cover rim lid, so there is problems of when carrying out centrifuge tube being inverted mixing or being placed in mixing on agitator, the material in pipe can outflow along cover rim surrounding, is carrying out detection by quantitative, when particularly measuring the less material of content, cause the inaccurate of result. The present invention, by covering centrifuge tube cover rim in the outside of centrifuge tube body, makes tube mouth directly be against pipe and covers, and so effectively avoids the liquid in pipe lower edge outflow along pipe lid.

6. the diameter of internal wall of pipe orifice opening part is less than the diameter of socket, when making centrifuge tube content amount few, even if keeping flat without touching pipe lid; On the other hand, when centrifuge tube content is liquid, it is possible to tilt centrifuge tube, makes liquid focus on internal wall of pipe orifice and body junction, it is achieved to take liquid convenient, after separating particularly in centrifugal solid-liquid, when taking supernatant liquid, submucosa components will not be sucked.

7. the diameter of internal wall of pipe orifice opening part is less than the diameter of socket, and the engaging making pipe lid and the mouth of pipe is convenient. Because cover rim lower port diameter is identical with socket diameter, namely cover rim lower port diameter is between internal wall of pipe orifice opening part diameter and mouth of pipe opening of external wall place diameter, just can be covered by lid so need not deliberately be directed at the mouth of pipe when lid pipe lid.

8. mouth of pipe outer diameter is more than socket diameter, and when centrifuge tube is placed on centrifuge tube shelf, mouth of pipe outer wall is carried on a shoulder pole on centrifuge tube shelf, makes centrifuge tube expose the part of centrifuge tube shelf many, is more beneficial for picking and placeing of centrifuge tube.

9. soft folded structure has two soft foldings be more beneficial for the unlatching of pipe lid and cover, and relative to a soft folding, the knuckle of each soft folding of structure of two soft foldings is little, increases the service life of soft folded structure. The length of two soft folding interludes is less than or equal to the height of cover rim, and the deformation strength that when this makes lid upper tube cap, soft folded structure produces is relatively small, makes pipe lid tighter when covering.

10. cover rim outer wall arranges outside protrusion and forms projection, mouth of pipe outer wall arranges outside protrusion and makes to be formed in the space of V-arrangement depression, protruding and depression can snap-fit, make pipe lid cover tightr, and increase feel when pipe lid is opened and covers, thereby determine that pipe lid covers tightly.

11. the design of conical bottom is conducive to the use of a small amount of sample.

12. mouth of pipe outer wall is lower than internal wall of pipe orifice, pouring liquid is convenient, also makes open pipe lid convenient. Even if there is refluence phenomenon when pouring liquid, the liquid of refluence also can flow in V-arrangement space, does not have weight and loses, without polluting external environment.

13. spanner upsweeps and convex surface downward, convex surface is finger contact surface during open pipe lid, is more convenient for the unlatching of pipe lid, and convex surface has anti-slip veins, increases frictional force, is conducive to the unlatching of pipe lid. Being arranged on when once needing to open multiple centrifuge tube and more can highlight advantage of spanner, convex surface be provided with the protection being beneficial to finger.

14. arrange Hookean region in the middle of caping, the elastic modelling quantity of Hookean region is less than other regions, and Hookean region can be selected for the material such as polyurethane and polyurethane, when there is draught head inside and outside centrifuge tube, it is possible to produce deformation. As produced gas, variations in temperature in centrifuge tube in centrifuge tube, covering can cause with tube used for bottom pouring lid etc. and there is draught head inside and outside centrifuge tube, centrifugal overpressure conference causes pipe lid Self-bouncing, and it is excessively tight that the centrifugal little meeting of overpressure makes pipe lid cover, it is difficult to opens.

15. in small-sized centrifuge tube (such as below 20ml specification), Hookean region is set to the diameter border circular areas less than 2cm, when lid pipe lid, thumb can by Hookean region, and Hookean region produces deformation, when covering tightly pipe lid, malleation is formed in centrifuge tube, unclamping by the thumb on Hookean region, Hookean region deformation malleation discharges, and is prevented effectively from centrifuge tube internal gas pressure excessive.

16. soft folded structure and caping are rotationally connected, it is possible to effectively reduce the deformation angle of soft folding, the deformation angle of soft folding reduces, and acting on the power that pipe covers can diminish, and makes pipe lid be not easy to be flicked. On the other hand, the deformation angle of soft folding reduces, and is conducive to extending the service life of soft folding.

17. spacer is used for regulating pipe lid relative to the position of body and direction, enable pipe lid just to body, convenient cap pipe lid. The setting of spacer is particularly suited for cover rim height and arranges relatively larger centrifuge tube.

18. being provided with of rod is beneficial to use centrifuge tube concussion mixing tube substance in vivo, it is particularly suited for the different liquids that polarity spectrum is bigger, for instance the preparation of microemulsion. Rod is threaded the result of use strengthening rod.
