The upper end socket sealing gag 30 of outer tube 10 and impermeable inner tube 20 will be centrifuged；Wherein, impermeable inner tube 20 is that top and bottom are equal
Offer the tubular body structure of the mouth of pipe, be equiped with the upper end of impermeable inner tube 20 one be used for the push pipe mouth of impermeable inner tube 20 and
The permeable screens 40 that bottom tube mouth is separated, permeable screens 40 are the trapezoidal bag shaped structure body of axial cross section, permeable screens 40
Port side wall and the internal perisporium of impermeable inner tube 10 be fixed as one.In this way, pass through the impermeable inner tube 20 and permeable screens set up
40 can change conventional centrifugal pipe by body+sealing cover combined structure form, when will centrifugation outer tube 10, impermeable inner tube 20 and sealing-plug
After the assembling of lid 30 is integrated, puncture processing can be carried out to sealing gag 30 by instruments such as syringes, so as to impermeable inner tube 20
Interior injection biological sample solution, because filtration treatment early stage to biological sample solution can be achieved in the effect of permeable screens 40, make
The larger material composition of the particle diameters such as organelle, large biological molecule is retained in impermeable inner tube 20 (i.e.：Permeable screens 40
In superjacent air space), and the less material composition of other particle diameters or liquid can then pass through permeable screens 40 and impermeable inner tube 30
Bottom tube mouth is leaked in centrifugation outer tube 10, because permeable screens 40 are using trapezoidal bag shaped structure is similar to, utilizes permeable screens
Inclined-plane form possessed by 40 waist edge side wall can be effectively increased the filter area to biological sample solution；Based on this, due to oozing
Filter net 10 can carry out filtration treatment early stage to biological sample solution, so as to effectively improve the centrifugation point to biological sample solution
From effect, shorten the run time of the rotary substrates such as time and the centrifuge of centrifugation, reaching reduces energy consumption and raising work
Make the purpose of efficiency.
Preferably, to improve the filter effect to biological sample solution, the permeable screens 40 of the present embodiment can root
Shaping is enclosed by filter membranes such as composite fibre miillpore filters or polyethersulfone membranes according to concrete condition.
To optimize the structure of whole centrifuge tube to greatest extent, the facility for being dismounted and being safeguarded to building block is improved
Property, the impermeable inner tube 20 of the present embodiment include pressing on fixation ring portion 21 on the end face of the top ports of centrifugation outer tube 10 and by
The bottom surface of fixed ring portion 21 and the interior pipe portion 22 that aftershaping is extended downwardly around the inner ring opening's edge axial direction for fixing ring portion 21,

Upper end periphery wall on be provided with for centrifugation the second external screw thread area b that is threadedly coupled of outer tube 10, and interior pipe portion 22
The trapezoidal relief port c of the axial cross section that is opened up on bottom then bottom tube mouths as impermeable inner tube 20, permeable screens 40
Port side wall be fixed on the collar extension perisporium of fixed ring portion 21, and centrifugation outer tube 10 upper end periphery wall on set
There is the 3rd external screw thread area d for being threadedly coupled with sealing gag 30.Thus, centrifuge outer tube 10 by the second external screw thread area b with
After the thread bush of impermeable inner tube 20 is connected in one, relation can be socketed by centrifuge tube by sealing gag 30 and screw thread between the two again
Each building block rapidly assemble and be integrated, and be advantageous to that all parts are quickly disassembled and safeguarded；Meanwhile by
In impermeable inner tube 20 bottom tube mouth (i.e.：Relief port c) can be beneficial to warp using bell shape or trapezoidal structural form is similar to
The material composition that permeable screens 40 filter is crossed equably to drop onto in centrifugation outer tube 10.
To avoid by the material composition that impermeable inner tube 20 leaks because between intrusion centrifugation outer tube 10 and impermeable inner tube 20
Gap in and influence centrifugal separating effect or be not easy to later stage cleaning and maintenance to part, in the upper end of centrifugation outer tube 10
Internal perisporium on be provided with one be used for block be formed at interior pipe portion 22 periphery wall and centrifugation outer tube 10 internal perisporium between seam
The closure ring 11 of gap.
As a preferred scheme, for ease of by whole centrifuge tube be installed in the rotary substrates such as centrifuge or from
On vascular stents, support arm 12 is additionally provided with the periphery wall of centrifugation outer tube 10.
To realize effective closure to the push pipe mouth of impermeable inner tube 20, so as to ensure the sealing property of whole centrifuge tube, this
The sealing gag 30 of embodiment includes one and is socketed simultaneously with centrifuging the upper end of outer tube 10 and the upper end screw thread of impermeable inner tube 20
