a plurality of micropores which are distributed at equal intervals are formed in the absorbent cotton, and the micropores are used for circulating liquid when the liquid is sucked by the liquid transferer;
the bottom of suction end is provided with the absorption point, the absorption point is the cone structure, the absorption point is used for adsorbing the trace waste liquid of remaining at centrifugal pipe wall and tube bottom.
As still further aspects of the utility model: the tip fixedly connected with link of suction head body, the top of link cup joints with the pipettor end is sealed.
As still further aspects of the utility model: the inner wall of link is provided with the protruding portion, the protruding portion is elastic structure, the protruding portion is used for improve the compactness between link and pipettor end when butt joint.
As still further aspects of the utility model: the connecting end and the suction head body are integrally formed and communicated with each other.
Compared with the prior art, the utility model has the beneficial effects that:
through setting up absorption point, absorption cotton, micropore, absorption point is the structure of making for absorption cotton, makes absorption point compliance can adjust the absorption angle to absorption point absorbs the trace waste liquid that remains at centrifugal pipe wall and bottom of the tube, and absorption cotton adsorbs trace waste liquid, and trace liquid passes through the micropore and adsorb on absorption cotton surface, thereby avoids the waste liquid to flow out the suction head body and causes the circumstances of pollution to laboratory environment.
