The working principle is as follows: after the quantitative cylinder is inserted into the bottle cap, the bottle cap is installed on the reagent bottle and screwed down, and finally the plunger is inserted into the liquid discharge pipe of the quantitative cylinder, and the installation is finished. Because plunger and quantitative section of thick bamboo are the glass material, can produce the error during glass shaping, so the stopper is leaving the factory according to the specific size adjustment stopper of the quantitative section of thick bamboo position on the metal pole of each installation, and the rigidity of later stopper can not remove.

When taking out the liquid in the reagent bottle, the plunger is lifted to reach the designated scale of the required reagent volume, the reagent is sucked into the pipette and flows into the liquid discharge pipe, then the plunger is pressed down, and the reagent passes through the liquid discharge pipe to reach the external container due to the one-way valve arranged in the pipette.

Furthermore, the surface of the part of the quantitative cylinder, which is in contact with the bottle cap, is a frosted surface, and the surface of the plunger is a frosted surface.

Further, a through hole for ventilation is formed in the bottle cap.

Furthermore, the bottle cap is provided with a slope for increasing the contact area between the liquid discharge pipe and the bottle cap at the position in contact with the quantitative cylinder, and glue for adhesion is filled between the slope and the liquid discharge pipe.

Furthermore, the reagent bottle can be a thick-bottom reagent bottle with better stability, and a transparent reagent bottle or a brown reagent bottle can be selected according to whether the reagent stored in the bottle is easily decomposed by light.

The utility model has the advantages as follows:

1. the utility model discloses a bottle lid of spiral shell type has replaced traditional glass stopper, rubber buffer for the batcher is connected more firmly with the reagent bottle, and the installation is dismantled very conveniently.

2. The utility model adopts the design of the quantitative cylinder with external installation, and the quantitative cylinder only has the liquid absorbing pipe part extending into the reagent bottle, and has no requirement on the bottle mouth size of the reagent bottle and wide application range.

3. The bottle cap is provided with a slope at the position contacting with the quantitative cylinder and is filled with glue for adhesion, and the surface of the contact part of the quantitative cylinder and the bottle cap is a frosted surface, so that the quantitative cylinder and the bottle cap are more firmly connected, and looseness is avoided.

4. The plunger surface is set to the frosting, has increased the frictional force of plunger and quantitative section of thick bamboo inner wall, prevents that the plunger from crossing smooth messenger's reagent volume of taking and appearing the error.

5. The bottle cap is provided with a through hole for ventilation, so that the pressure inside and outside the reagent bottle is kept consistent, and the plunger is freely pulled to take the reagent.
