Outer gas outlet is not disposed on same straight line.
Use said structure, increase the gas in external environment and enter the path of centrifuge tube, reduce the inside and outside direct convection current of gas
Probability, even if the gas that also can reduce when pressure regulation is strong in external environment enters the probability of centrifuge tube, improve thin further
Born of the same parents' separation purity.
More preferably: be fixed with rubber tube on described outer gas outlet, in described rubber tube, be provided with ball；Described rubber
The diameter of pipe is gradually reduced on the direction away from outer gas outlet from outer gas outlet, and the diameter of ball is between the maximum of rubber tube
Between diameter and minimum diameter.
Use said structure, increase external environment gas and enter the difficulty of centrifuge tube, reduce the gas in external environment enter from
The probability of heart pipe, improves cell separation purity further.
More preferably: described annular sidewall is formed by connecting by spaced side drainage screen and collateral dagger.
Use said structure, strengthen the face that may filter that, improve and filter purification efficiency.
More preferably: described filter chamber is inverted cone.
Use said structure, narrow under filter chamber, impulse force during filtration can be increased, accelerate filter efficiency；Filter chamber simultaneously
Bottom and centrifuge tube between relative to point open, convenient observe filtering phenomenon.
More preferably: the side of described ring skeleton is provided with takes boss.
Use said structure, easy disassembly cell filter, reduce the residuals on cell filter to operator
Impact.
In sum, this utility model has the advantages that
1, filter process valve, the ball position in rubber tube be can open and close by regulation and external environment and centrifuge tube regulated
Between pressure so that filter be smoothed out；
2, in filter process, the upper end of ring skeleton and centrifuge tube is abutted and is played by elastic seal ring close between the two
The effect of envelope, reduces impurity and pollutes；In gas centrifuge tube to be entered in external environment, need the rubber tube through carrying ball, outer
Communicating pipe and interior communicating pipe, and outer gas outlet and interior gas outlet be not provided with on the same line, the distance passed through is relatively long and road
Journey is the most tortuous, can reduce the gas in external environment and enter the probability of centrifuge tube；Improve cell separation purity further.
