The utility model compared with prior art, has following good effect:

1. by controlling the volume of diameter capillaceous and dropper prostomum body, can realize the quantitative control of dropping liquid.

2. the setting of dropper reinforcement can significantly increase the intensity of dropper, effectively prevents dropper fracture.

3. radial reinforced rib is set between dropper and outer tube can significantly increase bulk strength of the present utility model, prevents distortion, increases sealing.

4. positive stop lug boss is provided with breach, more easily unloading sample cup lid and sample cup body.

5. when sample cup lid covers on outer tube, the conical boss of sample cup lid inner wall of end and the quantitatively tight-lipped close fit of suction dropper dropper, formed like this secondary seal that sample cup lid coordinates with outer tube, significantly improved the sealing that sample cup lid coordinates with outer tube, Seepage has occurred while effectively preventing sample and reagent mix.

6. three bulge loops in sample cup body have significantly improved the sealing that sample cup body coordinates with outer tube, thereby have significantly improved the sealing between quantitative suction dropper and sample cup, and Seepage occurs while further preventing sample and reagent mix.
