Beneficial effect of the present invention:

1. when centrifuge tube covers, the cover rim of pipe lid is fastened in the V-arrangement space of mouth of pipe inside and outside wall formation, engaging area is large, make engaging tightr, extraneous bacterium or pollutant enter in pipe the binding face needed through mouth of pipe outer wall and cover rim outer wall, then through the binding face of internal wall of pipe orifice and 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 mouth of pipe inside and outside wall engage tightr, further realization prevents the pollution of managing interior material, more effectively prevents managing interior material and overflows along cover rim.

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

4. pipe lid and body link together by soft folded structure, and also link together with body all the time after pipe lid is opened, pipe lid is not easily lost, obscured.

5. current centrifuge tube is all enter in pipe by cover rim lid, such Problems existing be centrifuge tube is carried out inversion mixing or be placed in oscillator mixes time, the material in pipe can outflow along cover rim surrounding, is quantitatively detecting, during the material that particularly mensuration content is less, 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 the effective like this liquid in pipe that avoids outflows along the lower edge of 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, also can not touch pipe lid even if keep flat; On the other hand, when centrifuge tube content is liquid, can tilt centrifuge tube, makes liquid focus on internal wall of pipe orifice and body junction, realizes getting liquid convenient, especially after centrifugal solid-liquid is separated, when getting supernatant liquid, can not suck submucosa components.

7. the diameter of internal wall of pipe orifice opening part is less than the diameter of socket, makes the engaging of pipe lid and the mouth of pipe 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 lid can be covered so deliberately need not aim at the mouth of pipe when lid pipe lid.

8. between lining pipe and body, form the cavity of sealing, can filling with insulation material in cavity, also can fill condensing agent, for keeping invisible spectro temperature in certain hour.Not isolabeling can be added in heat-barrier material and/or condensing agent, as different colours etc., be conducive to experiment grouping.

9. soft folded structure has two soft foldings be more conducive to 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 less, tighter when pipe lid is covered.

10. during lid pipe lid, inserted sheet is pressed in slot, and slot clamping inserted sheet holding tube lid covers state.The socket of slot is low wide and up narrow, and when lid pipe lid, slot accurately need not aim at inserted sheet just can make inserted sheet slip in slot, convenient.

11. inserted sheets are arranged on mouth of pipe inside outer wall, inserted sheet is vertically arranged, certain space is there is between inserted sheet and internal wall of pipe orifice, inserted sheet and internal wall of pipe orifice do not link together, also certain distance is there is thus between slot and cover rim inwall, keep cover rim inwall complete, prevent the pollution of managing interior material, also prevent from managing the outflow of interior material.

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

13. mouth of pipe outer walls are lower than internal wall of pipe orifice, and pouring liquid is convenient, also make open pipe lid convenient.Even if there is refluence phenomenon when pouring liquid, the liquid of refluence also can flow in V-arrangement space, there will not be weight to lose, and also can not pollute external environment.

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

Arrange Hookean region in the middle of 15. caping, the elastic modelling quantity of Hookean region is less than other regions, and 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, variations in temperature in centrifuge tube, covers to cause inside and outside centrifuge tube with tube used for bottom pouring lid etc. and there is draught head, and centrifugal overpressure conference causes pipe lid Self-bouncing, and it is too tight that the little meeting of centrifugal overpressure makes pipe lid cover, and is difficult to open.

16. in small-sized centrifuge tube (as below 20ml specification), Hookean region is set to the border circular areas that diameter is 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, unclamp by the thumb on Hookean region, Hookean region deformation malleation discharges, and effectively avoids centrifuge tube internal gas pressure excessive.

17. soft folded structures and caping are rotationally connected, and can effectively reduce the deformation angle of soft folding, and 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 the service life extending soft folding.

18. spacers are used for adjustable 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 useful for cover rim height and arranges larger centrifuge tube.

Being provided with of 19. rods is beneficial to use centrifuge tube concussion mixing tube substance in vivo, is particularly useful for the different liquids that polarity spectrum is larger, the preparation of such as micro emulsion.Rod is arranged the result of use that screw thread strengthens rod.
