Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figure 1, a kind of suction nozzle, including integrally formed head sucting body 10 and suction nozzle head 20；Head sucting body 10
It is provided with scale on outer wall, scale can be but be not limited to 100 μ L, 500 μ L, 1000 μ L scales；Suction nozzle head 20 is close to suction nozzle
One end of main body 10, matching internal are provided with filter core 30；The one end of suction nozzle head 20 far from head sucting body 10 is set on inner wall
Screw thread 21 is equipped with, screw thread 21 facilitates suction nozzle head 20 and pipettor clamping, prevents suction nozzle from being fallen from pipettor.
As preferred embodiment, head sucting body 10 is conical body, and head sucting body 10 is the main portions of suction nozzle,
