A kind of equipment.It, usually can not be accurate when in continuous flow centrifugation to centrifuge tube (centrifugal bottle) automatic sample in rotary head
Make in each centrifuge tube (centrifugal bottle) sample-adding amount one to being directed at centrifugal process amount of unbalance and be unable to control, centrifuge is caused to shake
Dynamic noise increases, and influences centrifugal effect.
Summary of the invention
The present invention mainly overcomes shortcoming in the prior art, proposes a kind of continuous centrifugal sample introduction part flow arrangement, should
When device is solved without being loaded on a small quantity in the fixed centrefuge experiment that compares, the problem of sample introduction unevenness.
The present invention solves technical solution provided by above-mentioned technical problem：A kind of continuous centrifugal sample introduction part flow arrangement, packet
Device noumenon and needle-valve are included, described device ontology is equipped with groove and several needle valve holes, separating tube, goes out liquid interface, described recessed
Slot position is disposed axially on the upper surface of device noumenon in the center of device noumenon, the needle valve hole, and the liquid interface out is radial
It is arranged on the periphery of device noumenon；The needle valve hole lower end is connected to by separating tube with liquid interface out, the needle valve hole and
Liquid separation slot is equipped between groove, the groove is connected to by liquid separation slot with the lower part of needle valve hole, and the needle-valve is mounted on needle valve hole
It is interior.
Further technical solution is that the groove has the feed liquor storehouse of the inlet, butterfly that are sequentially communicated from top to bottom.
Further technical solution is that the shape in the feed liquor storehouse is two isosceles trapezoid shape symmetrical above and below.
Further technical solution is that the bottom inner corner in the feed liquor storehouse is 135 degree.
Further technical solution is that the shape of the separating tube is L shape.
Further technical solution is that the upper surface of described device ontology is additionally provided with mounting hole.
Further technical solution is that the needle valve hole, separating tube, the number of liquid interface is four out, four needle-valves
Hole is evenly arranged on the surrounding of inlet.
Further technical solution is that described device ontology lower end surface is equipped with centralized positioning boss.
Advantageous effect of the invention is：Sample-adding precision can be improved in the present invention, reduces continuous flow centrifugation in the process because being loaded band
The imbalance come, to keep centrifugal process more steady；For the present invention without electric appliance control, it is low in cost that the processing is simple；Present apparatus institute
There is process using centrifugal principle, is not necessarily to additionaling power and control system；The present apparatus is ingenious in design, is not necessarily to pipeline, and accessory is few, by dress
It is convenient；The processing is simple for present apparatus integrated design, low in cost, durable.
Detailed description of the invention
