Abstract

The utility model discloses a rubber head dropper and belongs to the technical field of chemical experiment appliances. The rubber head dropper structurally comprises a rubber cap and a glass tube. The rubber head dropper is characterized in that an inverted cone backflow prevention pipe is fixedly embedded in the top end port of the glass tube; and scales are arranged on a tube body of the glass tube. The rubber head dropper has a simple structure and is convenient to use. According to the rubber head dropper, the corrosion on the rubber cap, which is caused by misoperation or volatilization of a reagent, can be effectively prevented and the service life of the rubber head dropper is effectively prolonged; and the required quantity of reagent can be more accurately sucked or dropwise added and more guarantee is brought to the accuracy of the experiment.

Description

A kind of glue head dropper
Technical field
The utility model relates to a kind of glue head dropper, belongs to chemical experiment apparatus technical field.
Background technology
Glue head dropper is claimed the Capsule dropper again, and it is a kind of instrument that is used to draw or drip small amount of liquid reagent, and the glue head dropper of using in the laboratory usually directly is enclosed within Capsule on the glass tube.Common Capsule does not have anti-corrosion capability, in experimental implementation, runs into the reagent volatilization of severe corrosive, or because of misoperation lies in experimental bench with glue head dropper, reagent is flow backwards, and all can cause corrosion to Capsule, seriously shortens its service life; Common glue head dropper does not have scale usually, and experimental implementation person normally according to the amount of the liquid that magnitude estimation drips of the glue head dropper mouth of pipe, is required more accurate experimental implementation to make troubles.
Summary of the invention
The purpose of the utility model is to provide a kind of can prevent effectively that Capsule is corroded and can prolong its service life, and has the glue head dropper of accurate measurement function.
The utility model is realized through following technical scheme: a kind of glue head dropper, comprise Capsule and glass tube, and it is characterized in that, the fixedly embedded back taper anti-return pipe that is provided with in the said glass tube top ports, said glass tube body is provided with scale.
Said anti-return pipe and glass tube sealing and fixing.
Compared with prior art, the beneficial effect of the utility model is, this kind glue head dropper is simple in structure, easy to use.This glue head dropper is provided with back taper anti-return pipe, can guarantee that air-flow can pass in and out Capsule smoothly to draw reagent, can effectively prevent again because of misoperation or reagent volatilization Capsule to be caused corrosion, effectively prolongs its service life; Said glass tube is provided with scale, can draw or drip the amount of required reagent more accurately, brings bigger guarantee for the accuracy of experiment.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1, Capsule, 2, the anti-return pipe, 3, glass tube, 4, scale.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this kind glue head dropper comprises Capsule 1 and glass tube 3, the fixedly embedded back taper anti-return pipe 2 that is provided with in said glass tube 3 top ports, said anti-return pipe 2 and glass tube 3 sealing and fixing; Capsule directly is enclosed within on the mouth of pipe of anti-return pipe and gets final product, this glue head dropper is provided with back taper anti-return pipe, can guarantee that air-flow can pass in and out Capsule smoothly and can effectively prevent because of misoperation or reagent volatilization Capsule to be caused corrosion to draw reagent, to have.
Said glass tube 3 bodys are provided with scale 4.
