Abstract

The utility model relates to a dropping bottle used in laboratory, which comprises a body 1 and a dropper 2; a rubber plug 3 is sleeved on the dropper 2; the rubber plug is covered on the bottleneck; and circular buffer cavity 4 is formed in the dropper on the top of the rubber plug. When used, the liquid in the dropping bottle can be fetched by operating a rubber head 5. The bottle of the utility model is used for storing experimental reagent, has the advantages of simple structure and convenient using, solves the problem of bonding of bottleneck and dropper in prior bottle, avoids contaminations, and improves the accuracy rate of experiment results.

Description

A kind of novel drop bottle

Technical field

The utility model relates to the novel drop bottle of a kind of laboratory or laboratory use.

Background technology

At present, instrument commonly used in laboratory or laboratory is exactly a glass wares, contain silica in the composition of glass, and silica can generate the silicate of etching glass with the alkaline matter effect, when glass and glass contact face have alkaline matter, can make between the glass and to corrode and bond, so alkaline reagent is contained in the ground drop bottle, can cause bottleneck and dropper to bond together, can't continue again to use.The reagent bottle of splendid attire alkaline reagent in the test, yet, use rubber very inconvenience again, need repeatedly get lid, put lid, repeatedly pick and place dropper, be easy to pollution, thereby influence the accuracy of experimental result according to paired other utensils.

The utility model content

The purpose of this utility model provides the drop bottle of splendid attire alkaline reagent a kind of simple in structure, easy to operate.

The utility model is achieved through the following technical solutions: a kind of novel drop bottle, comprise bottle, dropper, and dropper upper ring cap rubber stopper, rubbery plug lid is on bottleneck; The dropper on described rubber stopper top is provided with circular cushion chamber.

The beneficial effects of the utility model are that the result is simple, easy to use, have solved the adhesion problem of bottleneck and dropper in the past, have avoided various contaminations, have improved the accuracy rate of result of the test.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1 is that bottle, 2 is that dropper, 3 is that rubber tube, 4 is that cushion chamber, 5 is the glue head.

The specific embodiment

As shown in the figure, a kind of novel drop bottle comprises bottle 1, dropper 2, dropper 2 upper ring cap rubber stoppers 3, and rubbery plug lid is on bottleneck; The dropper on rubber stopper top is provided with circular cushion chamber 4; Operation glue head 5 can pick and place use with the liquid in the drop bottle during use.

The utility model is used to deposit the dress experiment reagent, the result is simple, easy to use, has solved the adhesion problem of bottleneck and dropper in the past, has avoided various contaminations, has improved the accuracy rate of result of the test.

Claims (2)

1. a novel drop bottle comprises bottle, dropper, it is characterized in that: described dropper upper ring cap rubber stopper, rubbery plug lid is on bottleneck.

2. a kind of novel drop bottle according to claim 1 is characterized in that: the dropper on described rubber stopper top is provided with circular cushion chamber.
