Abstract
The utility model relates to a burette which comprises a capsule and a suction tube, wherein the capsule is fixed at the top end of the suction tube. The burette is characterized in that a suction nozzle is arranged at the lower end of the suction tube, and the upper end of the suction tube has a gourd-shaped structure. The burette has the advantages of having strong adsorption capacity, effectively preventing the corrosion of the capsule and prolonging the service life of the capsule.
Description
Technical field
The utility model relates to a kind of dropper, belongs to the chemical laboratory apparatus.
Background technology
In chemical laboratory, dropper be the most frequently used instrument one of.It mainly is to be used to shift some a spot of chemical reagent, and the chemical reagent that has has extremely strong corrosivity, and is especially even more serious to the corrosivity of dropper capsule.Therefore, when shifting chemical reagent, must can not enter in the capsule by guarantee reagent.
Summary of the invention
The purpose of this utility model provides a kind of dropper, and this dropper can prevent effectively that chemical reagent from entering in the capsule, has avoided the capsule internal corrosion, has increased the service life of dropper.
The technical solution adopted in the utility model is:
A kind of dropper comprises capsule and suction pipe, and described capsule is fixed on the top of suction pipe, and the lower end of described suction pipe is provided with suction nozzle, and the upper end of described suction pipe is cucurbit shape structure.
Described suction nozzle is conical structure.
Described suction pipe and suction nozzle are structure as a whole.
The upper end of the utility model suction pipe is designed to cucurbit shape structure, the amount of reagent of inhaling when dropper more for a long time, inhale reagent and will be stored in the cucurbit structure, can not enter into capsule, avoided the corrosion of reagent to capsule; The utility model is provided with suction nozzle in order to strengthen the absorption affinity of suction pipe to reagent in the lower end of suction pipe, especially suction nozzle is designed to pyramidal structure.
The utility model has the advantages that: high adsorption capacity, prevent the capsule corrosion effectively, prolong the service life of capsule.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Wherein: 1, capsule, 2, suction pipe, 3, suction nozzle.
The specific embodiment
As shown in Figure 1, a kind of dropper, comprise capsule 1 and suction pipe 2, capsule 1 is fixed on the top of suction pipe 2, in order to strengthen the absorption affinity of 2 pairs of reagent of suction pipe, is provided with suction nozzle 3 in the lower end of suction pipe 2, this suction nozzle 3 is conical structure, the amount of reagent of inhaling when dropper enters into capsule 1 in order to prevent reagent more for a long time, and the upper end design of suction pipe 2 is cucurbit shape structure; For the ease of the making of suction pipe 2, suction pipe 2 and suction nozzle are designed to integrative-structure.
