Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
In order to required liquid can be extracted fast after centrifugal, the utility model provides a kind of fluid separation applications centrifuge tube, as shown in Figure 2-5, it comprises body 1, be provided with the pipe lid 2 covered tightly by body 1 in the upper end of body 1, be connected with at the bottom of pipe 3 in the lower end of body 1, being meant to of described flexible connection: at the bottom of pipe, 3 are fixedly connected with body 1 when centrifuge tube of the present utility model carries out centrifugal separation, and when carrying out after being separated moving liquid extraction, be then separated with body 1.Drainage pipe 11 is provided with, for the discharge of liquid in body 1 lower end.When centrifuge tube of the present utility model carries out centrifugal, at the bottom of pipe, 3 are fixedly connected with body 1, and now Drainage pipe 11 to be placed at the bottom of pipe in 3, and by 3 sealing up at the bottom of pipe, so as centrifugal time there will not be the leakage of liquid; With reference to Fig. 4, pipe lid 2 is provided with the cylinder 21 connecting liquid-transfering gun, this cylinder 21 in hollow tubular structure, and is connected with body 1; The interface place of cylinder 21 bottom surface and pipe lid 2 is provided with cruciform baffles agitated vessel 22, this cruciform baffles agitated vessel 22 is placed with sterile cotton (not shown) and sterile cotton is full of the inside of whole cylinder 21.Concrete, this cruciform baffles agitated vessel 22 is connected to cylinder 21 inwall and one-body molded with it, thus can prevent from experiment from carrying out middle sterile cotton falling in body 1.And by the inside of sterile cotton filling disks cylinder 21, the air that liquid-transfering gun can be made to carry effectively is filtered, preventing pollution.Cylinder 21 is stamped cap lid 4, when carry out centrifugal or do not use liquid-transfering gun to move liquid time, cylinder 21 on pipe lid 2 tightly covers (being in sealing state) by cap lid 4, when carrying out when using liquid-transfering gun moving liquid, then takes off cap lid 4, liquid-transfering gun is connected with cylinder 21, after connecting liquid-transfering gun, just can disposable discharge liquid, for collection, eliminate the time of repeatedly drawing waste, improve the efficiency of extraction.
As shown in Figure 3, be also provided with the taper tube wall 12 extending to Drainage pipe 11 one end in the lower end of body 1, body 1 is connected with Drainage pipe 11 transition by this taper tube wall 12, and its pyramidal structure can make liquid slowly concentrate on the one hand, finally flows to Drainage pipe 11; Also to be convenient on the other hand at the bottom of pipe 3 with the connection of body 1.Boss 13 is provided with, for tube connector lid 2 in the upper end of body 1.
In the present embodiment, pipe lid 2 is being set on boss 13 of sealing.Concrete, be have the screw thread of working in coordination on the outer wall of boss 13 and the inwall of pipe lid 2, by screwing pipe lid 2, boss 13 sealing can slowly cover tightly by pipe lid 2.
As shown in Figure 5, at the bottom of pipe, the upper end of 3 is provided with the conical depression 31 with taper tube wall 12 mating shapes, and then 3 can be made at the bottom of pipe to coordinate closely with body 1.Same, in this conical depression 31 He on taper tube wall 12, be provided with the screw thread of working in coordination, be sealedly attached to taper tube wall 12 to make conical depression 31.By screwing at the bottom of pipe 3, the conical depression 31 on it is coated taper tube wall 12 gradually, meanwhile 3 to be sealed by Drainage pipe 11 at the bottom of pipe.
As preferred technical scheme, the structure sealed by Drainage pipe 11 is sealing column 32, to be arranged at the bottom of pipe 3 inner and be fixedly installed at the bottom of pipe 3 bottom, at the bottom of pipe, 3 when sealing Drainage pipe 11, and sealing column 32 is inserted Drainage pipe 11 and Drainage pipe 11 is sealed filling.Sealing column 32 fills Drainage pipe 11, can not affect the separation of parting liquid to cell on the one hand; Then by liquid closed in centrifuge tube on the other hand, preventing pollution.
Concrete, the Drainage pipe 11 of the present embodiment is circular tube structure, and arranges from large to small along discharge direction diameter, and minimum diameter is identical with the diameter of sealing column 32.Drainage pipe 11 is arranged to narrow circular tube structure, liquid can be made to discharge in order, greatly improve the purity of collecting liquid.And the diameter of sealing column 32 is identical with the minimum diameter of Drainage pipe 11, when sealing column 32 can be made to insert Drainage pipe 11, whole connection sealing No leakage, centrifugal effect when ensure that centrifugal.
In the present embodiment, cylinder 21 and the inwall of cap lid 4 are also provided with the screw thread of working in coordination, and cylinder 21 is covered tightly by threaded engagement by cap lid 4, plays the effect of sealing equally.
In the present embodiment, body 1 is also provided with scale, and this scale is arranged on the top of at the bottom of pipe 3, for the measurement of liquid volume.
Below use procedure of the present utility model is described:
First, open pipe lid 2, adding liquid in body 1, then lid upper tube cap 2 (now at the bottom of pipe 3 be fixedly connected with body 1), carries out centrifugal work; After centrifugal end, open the cap lid 4 above pipe lid 2, liquid-transfering gun is connected on the cylinder 21 of pipe lid 2, to open at the bottom of pipe 3 afterwards, start liquid-transfering gun and discharge opeing is carried out to the liquid in body 1, the liquid of separation is discharged in order from Drainage pipe 11, finally, until the liquid of required extraction is discharged, collect, complete extraction work.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
