Beneficial effects of the present invention：

1. the cover rim of lid is fastened in the V-arrangement space of the mouth of pipe inside and outside wall formation when centrifuge tube is covered, engaging area is big, makes Engaging is even closer, and extraneous bacterium or pollutant need the binding face by mouth of pipe outer wall and cover rim outer wall into managing, then By internal wall of pipe orifice and the binding face of cover rim inwall, this process is difficult, therefore the present invention effectively prevent material in pipe Pollution, also effectively prevent in pipe that material overflows along cover rim.

2. it is hollow between cover rim inwall and cover rim outer wall, cover rim inwall and cover rim outer wall is produced when covering slightly Deformation, it is even closer that the strength of deformation can engage cover rim and mouth of pipe inside and outside wall, and further realizing prevents material in pipe Pollution, it is more efficient to prevent that material overflows along cover rim in pipe.

3. the setting of spanner, is easy to the switch of lid.

4. soft folded structure links together lid and body so that lid is also connected to one with body all the time after opening Rise, lid is difficult to lose, obscured.

5. current centrifuge tube is all to enter cover rim lid in pipe, the problem of so existing is that centrifuge tube is being carried out to be inverted mixed Even or be placed in when being mixed on oscillator, the material in pipe can outflow along cover rim surrounding, quantitatively detected, particularly determine and contain When measuring less material, the inaccurate of result is caused.The present invention is made by the way that centrifuge tube cover rim to be covered to the outside in centrifuge tube body Tube mouth is directly against in lid, so effectively avoids lower edge outflow of the liquid in pipe along lid.

6. diameter at internal wall of pipe orifice opening is less than the diameter of socket, when making centrifuge tube content amount few, even if keeping flat Lid will not be touched；On the other hand, when centrifuge tube content is liquid, centrifuge tube can be tilted, liquid is focused on the mouth of pipe Inwall and body junction, realization take liquid convenient, especially after centrifugal solid-liquid separation, when taking supernatant liquid, will not suck down Composition of layer.

7. the diameter at internal wall of pipe orifice opening is less than the diameter of socket, the engaging of lid and the mouth of pipe is set more to facilitate.Because Cover rim lower port diameter is identical with socket diameter, i.e. cover rim lower port diameter diameter and mouth of pipe opening of external wall at internal wall of pipe orifice opening Between place's diameter, so just lid can be covered without being deliberately directed at the mouth of pipe in lid lid.

8. being formed between lining pipe and body in the cavity of sealing, cavity be able to can also be filled cold with filling with insulation material Solidifying agent, for keeping invisible spectro temperature in certain time.Not isolabeling can be added in heat-barrier material and/or condensing agent, Such as different colours, are conducive to experiment packet.

9. cover rim outer wall sets outside protrusion to form projection, the outside protrusion of mouth of pipe outer wall setting makes in the space of V-arrangement Form depression, raised and depression can snap-fit, cover lid even closer, and increase when lid is opened and covered Feel, thereby determines that lid is covered tightly.

10. the use being designed with beneficial to a small amount of sample of conical bottom.

11. mouth of pipe outer wall is less than internal wall of pipe orifice, pouring liquid more facilitates, and also make it that open pipe lid more facilitates.Toppling over Even if there is refluence phenomenon during liquid, the liquid of refluence can be also flowed in V-arrangement space, be not in that weight is lost, will not also be polluted External environment.

12. spanner upsweeps and convex surface is downward, finger contact surface when convex surface is open pipe lid is more convenient for lid Unlatching, convex surface has an anti-slip veins, increases frictional force, be conducive to the unlatching of lid.It is many that being arranged on of spanner once need unlatching Advantage, the protection being provided with beneficial to finger on convex surface can be more highlighted during individual centrifuge tube.

13. caping middle setting Hookean region, the elastic modelling quantity of Hookean region is less than other regions, Hookean region can select The material such as polyurethane and polyurethane, when there is draught head inside and outside centrifuge tube, can produce deformation.As produced gas in centrifuge tube Temperature change in body, centrifuge tube, covering can cause the presence of draught head inside and outside centrifuge tube with opening lid etc., and centrifugation overpressure is big Lid Self-bouncing can be caused, overpressure is small that lid can be made to cover too closely for centrifugation, it is difficult to open.

14. in small-sized centrifuge tube (such as below 20ml specifications), Hookean region is set to the circle that diameter is less than 2cm Domain, in lid lid, thumb can be by Hookean region, and Hookean region produces deformation, when covering tightly lid, is formed just in centrifuge tube Pressure, unclamps by the thumb on Hookean region, the release of Hookean region deformation malleation, is prevented effectively from centrifugation intraductal atmospheric pressure excessive.

15. soft folded structure is rotated with caping and is connected, the deformation angle of soft folding can be effectively reduced, the deformation angle of soft folding subtracts Small, the power acted in lid can diminish, and make lid be not easy to be flicked.On the other hand, the deformation angle of soft folding reduces, favorably In the service life for extending soft folding.

16. spacer is used for adjusting position and direction of the lid relative to body, enable lid just to body, convenient cap Lid.The setting of the spacer cover rim that is particularly suitable for use in highly is set than larger centrifuge tube.
