As improvement of the present utility model, the lid includes lid and folding part, and the lid passes through folding part and card Button connection.

By using above-mentioned technical proposal, opening and the closing of buckle and fixture block are conveniently realized by the setting of folding part.

As improvement of the present utility model, the lid lower surface is provided with sealing ring.

By using above-mentioned technical proposal, sealing ring is provided for sealed tube body and lid, prevent place or from The liquid during heart in centrifuge tube oozes out.

As improvement of the present utility model, the lid is provided with through hole, and breather pipe is provided with the through hole, described logical Dust cap is also connected with tracheae.

By using above-mentioned technical proposal, negative pressure can be produced in centrifuge tube in centrifugation, and breather pipe and dust cap Set, when needing to open, by opening the lid of clamping, lid can be made to depart from body.

As improvement of the present utility model, the dust cap is connected by a connecting plate with the lid.

By using above-mentioned technical proposal, connecting plate is provided for linking together lid and dust cap, prevents from preventing Dirt losing of cover.

As improvement of the present utility model, the upper end of the breather pipe is provided with rubber valve.

By using above-mentioned technical proposal, dustproof effect is played in the setting of rubber valve.

In summary, the utility model has the advantages that：Lid is set to fasten by fixture block and bayonet fittings On body, and in fixture block and buckle clamping, certain gap is left between buckle and body, is conveniently hung over so as to realize Effect on various hangers, and without setting independent hanger individually for each suspension member.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of centrifuge tube, as shown in figure 1, being made up of body 1 and lid 2；Lid 2 passes through the card on buckle 23 and body 1 The fastening lid of block 11 is on body 1.Formed between buckle 23 and body 1 for the gap be affiliated to, can different size from Heart pipe hanger is cost-effective without the centrifuge tube shelf of special configuration different size on common hanger.

As depicted in figs. 1 and 2, the top of body 1 is cylinder, and bottom is taper, can so make centrifugation more thorough.Pipe Fixture block 11 on body 1 is equally spaced in the circumference of body 1, and fixture block 11 interlocks with the buckling hole 231 on the buckle 23 of lid 2 Close.Body 1 is that transparent material is made and graduation mark fin 12 is additionally provided with outer wall, not only can be to the liquid bulk in centrifuge tube Product measures, moreover it is possible to increases the contact area of hand and body 1, in fluid injection and when taking liquid, makes body 1 be not easy to slide, cause sample This damage.

As shown in Figures 3 and 4, lid 2 is made up of lid 21, folding part 22, breather pipe 24, dust cap 25 and sealing ring 26. The edge annular of lid 21 is placed equidistant four folding parts 22 and buckle 23, and buckle 23 is integrally set by folding part 22 and lid 21 Put, buckle 23 can be opened or turned up by the bending of folding part 22.

Through hole 211 is provided with lid 21, breather pipe 24 is set in through hole 211, the top of breather pipe 24 is provided with rubber clack Film 241.Lid 21 is connected with dust cap 25 by connecting plate made of elastomeric material 251, and dust cap 25 is fastened on breather pipe 24 On.In centrifugal process, negative pressure can be formed in the centrifuge tube of sealing so that lid 2 is not easy to open, by opening dust cap 25, Bypass air through breather pipe 24 to enter in centrifuge tube, make centrifuge tube inside and outside air pressure balance, can easily open lid 2.While by In the presence of rubber valve 241, it can also be sampled by breather pipe 24, when sampler inserts, rubber valve 241 can just become Shape forms opening；After the completion of sampling, sampler is extracted, rubber valve 241 is closed automatically, and debris will not be made to enter in centrifuge tube, Pollute sample.

Simultaneously sealing ring 26 is additionally provided with lid 21；, can more preferable closed centrifuge tube when the lid 2 is covered body 1.

The course of work：Open lid 2, by sample centrifuge injection centrifuge tube in, cover lid 2, by centrifuge tube be put into from Centrifugal treating is carried out in scheming.Centrifuge tube is taken out, dust cap 25 is opened, admits air into centrifuge tube, inside and outside equilibrium centrifugation pipe Air pressure；Dust cap 25 is covered, centrifuge tube is hung on hanger, it is stand-by.During sampling, dust cap 25 is opened, sampler is passed through logical Tracheae 24, which is stretched into centrifuge tube, to be sampled, and can also be opened lid 2, is sampled.After use, centrifuge tube is carried out clear Drying is washed, is afterwards hung over centrifuge tube standby on hanger.

This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
