The second Pasteur pipette is used for sucking and transferring 0-50 microliters of trace liquid, when the device is used, the first Pasteur pipette is taken down, the upper end of the second Pasteur pipette is inserted into the second mounting hole, and the second rubber dropper is squeezed and loosened again to suck the trace liquid; the utility model provides an elastic rubber plug both can be used for installing first pasteur straw, can install second pasteur straw again, consequently this device has the absorption transfer of crude liquid and trace liquid concurrently.
Further limiting, an inward concave groove is formed in the side wall of the sleeve, and the second rubber dripper is arranged in the groove.
Further, the outer side wall of the sleeve is provided with anti-skid protrusions.
The utility model has the advantages that:
1. in the application, the transfer of trace liquid (or gametes and embryos) of the first Pasteur pipette and the second Pasteur pipette can be subjected to micro control through the second rubber dropper, so that the risk of misoperation is reduced, and the first Pasteur pipette and the second Pasteur pipette are installed on the sleeve and captured by the sleeve, so that the stability of liquid taking is improved, and the risk of misoperation is reduced; and because the first Pasteur pipette and the second Pasteur pipette can be installed, the sucking and transferring of the crude liquid and the trace liquid are realized.
2. Be equipped with filter pulp and graphite alkene filter screen in first pasteur straw, through filter pulp prevention most of liquid pollutants, graphite alkene filter screen adsorbs extremely tiny pollutant, the cross contamination that leads to in avoiding liquid to suck first rubber water dropper can be very big.
