Traditional method is exactly repeated multiple times limiting dilution assay, limiting dilution assay cell dilution to every 2 ~ 5 μ L of theoretic 1 cell, then carry out unicellular separation with the cell suspension that pipettor is drawn corresponding volume.But in actual operation, this method efficiency is not high, generally in 20% left and right, a large amount of blank well and many cells holes (cell count is more than or equal to 2) that exist need researchist to observe eliminating, waste time and energy.This working method is simple, but whole Period Process is long, wastes time and energy, and can not ensure obtaining of individual cells.
Unicellular micrurgy, pipettor volume inconvenient operation under the microscope bigger than normal, and poor stability are moved liquid point tip diameter too large in addition, multiple cells of different aspects under the large and easy inspiration field of microscope of liquid absorption.
High-end flow cytometer not only can be realized the hyperchannel sorting (fluorescence-activated cell sorting, FACS) of viable cell at present, can also carry out single celled separation plantation sorting, for technical foundation is established in large-scale unicellular research.But these size separation equipments are expensive, be also difficult at present popularize.Due to FACS process because relate to digestion and the sorting of cell, thereby may exert an influence and affect the accuracy of experimental result the activity of cell and surface markers.And flow cytometer obtain be the mean value of cell colony information, can not reflect unicellular inside Physiology and biochemistry change.
Above the whole bag of tricks, the not high or inconvenient operation or expensive of some method efficiency, easily damaging cells, therefore, explores that one is simple to operate, unicellular separation method is very meaningful fast and efficiently.
Summary of the invention
In order to address the above problem, further simplify technology mode, handled easily, improves accuracy and efficiency, alleviates workload, not damaging cells, convenient detect unicellular interior biochemical reactions, the utility model provides a kind of oscillation mode single cell separator, can sharp separation unicellular, can aseptic technique in Biohazard Safety Equipment, use after the each part detachable of separator, sterilizing, simple to operate and to the not damaged of cell own, also help follow-up cultivation and the detection of cell.
The technical solution of the utility model is:
A kind of oscillation mode single cell separator, comprise bottom vibrator, upper strata rotator and kapillary, bottom vibrator and upper strata rotator composition inverted T shape, bottom vibrator is discoid, upper strata rotator is cylindrical shape, on the rotator of upper strata, be provided with at least one circle kapillary, kapillary pipeline is S type bending, and kapillary is glass material, in bottom vibrator, be provided with vibrating motor and be connected with upper strata rotator, the top of upper strata rotator inner chamber is provided with rotation motor.
At least one circle kapillary is declined and is fixed on rotator by the clockwise spiral of fixing buckle of rotator outside, upper strata.
At least one circle material capillaceous can be glass material.
At least one circle internal diameter of the pipeline capillaceous is decreased to the size matching with cell gradually to spout from influx.
The beneficial effects of the utility model are: the utility model is unicellular in order to isolate from cell suspending liquid.By at least one circle kapillary arranging on the rotator of upper strata, the S-type bending of its pipeline, the cell suspending liquid in pipeline, under the vibration of bottom vibrator and the rotation of upper strata rotator, is separated from cell suspending liquid unicellular.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figures 1 to 4, a kind of oscillation mode single cell separator of the present utility model, comprise bottom vibrator 10, upper strata rotator 20 and kapillary 30, bottom vibrator 10 and upper strata rotator 20 form inverted T shape, bottom vibrator 10 is discoid, upper strata rotator 20 is cylindrical shape, on upper strata rotator 20, be provided with at least one circle kapillary 30, kapillary 30 pipelines are S type bending, kapillary 30 is glass material, in bottom vibrator 10, be provided with vibrating motor 104 and be connected with upper strata rotator 20, the top of upper strata rotator 20 inner chambers is provided with rotation motor 202.
Kapillary 30 is declined and is fixed on upper strata rotator 20 by the clockwise spiral of fixing buckle 201 of upper strata rotator 20 outsides.
The material of kapillary 30 is glass material.In present embodiment, kapillary 30 materials are quartz.
The internal diameter of the pipeline of kapillary 30 is decreased to the size matching with cell gradually to spout from influx.
Bottom vibrator 10 and described upper strata rotator 20 materials are stainless steel or metal.In present embodiment, bottom vibrator 10 and upper strata rotator 20 materials are metallic aluminium.
Bottom vibrator 10 outsides comprise base 102 and spring 101, inner involving vibrations motor 104 and bearing 103, and bottom vibrator 10 vibrates up and down by vibrating motor 104.
