Furthermore, a liquid-transferring head of the vacuum pump is inserted into the head of the suction head to be combined with the vacuum pump into an assembly, the XYZ three-degree-of-freedom moving mechanism drives the assembly to move to the sampling bottle to suck a sample, a liquid-sucking port of the puncture needle is punctured into a rubber plug of the sampling bottle with a cover to stretch into the bottle to suck the liquid, the sucked sample liquid is stored in the liquid storage cavity, and then the application liquid in the liquid storage cavity is transferred to a sample-adding position through the XYZ three-degree-of-freedom moving mechanism.
Furthermore, a liquid-transferring head of the vacuum pump is inserted into the head of the suction head to be combined with the vacuum pump into an assembly, the XYZ three-degree-of-freedom moving mechanism drives the assembly to move to the sampling bottle to absorb a sample, a liquid-absorbing opening of the puncture needle is directly inserted into the uncovered sampling bottle to absorb the sample, the absorbed sample liquid is stored in the liquid storage cavity, and then the application liquid in the liquid storage cavity is transferred to a sample-adding position through the XYZ three-degree-of-freedom moving mechanism.
Adopt above-mentioned technical scheme, the utility model discloses an increase the pjncture needle at the suction head front end to cooperation XYZ three degree of freedom moving mechanism, during the sample bottle of area lid inhales a kind, passes the lid plug through the front end pjncture needle and to inside imbibition, and the in-process saves the machine step of uncapping, improves the efficiency that liquid shifted, and sealed imbibition reduces risks such as sample pollution, propagation. Is particularly suitable for transferring sample liquid sensitive to pollution of a nucleic acid extraction device.
