Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
Have as shown in figure 1, the suction nozzle 10 of the present embodiment includes the receiving portion 11 being connected and connecting portion 12, receiving portion 11
Accommodating chamber 111, connecting portion 12 are gradual from outside to inside with the shoulder hole 121 connected with accommodating chamber 111, the aperture of shoulder hole 121
Reduce, to adapt to various sizes of measuring pipette.
Using the suction nozzle of the present embodiment, the connecting portion 12 of suction nozzle 10 has shoulder hole 121, and the aperture of shoulder hole 121 is by outer
It is gradually reduced to interior, different apertures adapts to various sizes of measuring pipette, i.e. a suction nozzle can use a variety of measuring pipettes.
So, can be replaced in the prior art using the suction nozzle that different size is or else needed to use after above-mentioned suction nozzle, said one suction nozzle
A variety of different sizes suction nozzle using very convenient.
In the present embodiment, shoulder hole 121 includes the first hole section 1211, the second hole section 1212 and the 3rd hole being sequentially connected
Section 1213, the aperture of the first hole section 1211 are more than the aperture of the second hole section 1212, and the aperture of the second hole section 1212 is more than the 3rd hole
The aperture of section 1213.Said one suction nozzle is adapted to the measuring pipette of three kinds of sizes.Certainly, the number of the hole section of shoulder hole is simultaneously
Not limited to this, it can be selected as the case may be.
In the prior art, insecure between suction nozzle and measuring pipette after suction nozzle being enclosed on into measuring pipette, suction nozzle easily falls,
Operating efficiency is influenceed, in view of the above-mentioned problems, in the present embodiment, suction nozzle also includes fixture, fixture is set in connecting portion 12
