Abstract
A liquid sampler that belongs to the technical field of chemical experimental instrument comprises a sealing cover with two axial through holes, an air inlet pipe and a liquid outlet pipe with two opening ends that are arranged in the through holes respectively and an ear washing bulb that is connected with the upper end of the air inlet pipe. The liquid sampler can safely and accurately take the liquid from the reagent bottle and is suitable to the highly acid, alkaline, strong corrosive and strong soluble liquid reagents, thereby avoiding environmental pollution from occurring due to the spilt reagent and preventing the reagent from harming the body health of the experimenter.
Description
Technical field
The utility model belongs to the chemical experimental instrument technical field, relates to a kind of liquid getting device.
Background technology
The medicine overwhelming majority used in the chemical experiment is a liquid condition; and wherein the overwhelming majority has toxicity and niff; the liquid drug of using in experiment is got from reagent bottle mostly; spill through regular meeting when from reagent bottle, getting liquid reagent; arrive many; be not easy control; not only waste medicine but also cause the smell of medicine to be full of the laboratory; in addition; the medicine that is sprinkling upon the bottleneck outside also can be bonded on the product staff of getting it filled once more, is harmful to health, and the control method commonly used of getting liquid measure is to utilize dropper to drip control; dropper is got very pettiness of liquid measure at every turn; use inconvenient, can only be as supplementary means, and cause the smell of medicine to distribute easily.
The utility model content
The purpose of this utility model provides a kind of can accurately control to get liquid measure, liquid getting device free from environmental pollution.
The utility model is realized above-mentioned purpose by the following technical solutions: a kind of liquid getting device, comprise the seal cover that is provided with two axially extending bores, and be separately installed with the air inlet pipe and the drain pipe of both ends open in its through hole, the air inlet pipe upper end is connected with ear washing bulb.
Drain pipe is the straight tube that has elbow, and wherein straight-tube portion is inserted on the seal cover, and drain pipe is longer than the length of air inlet pipe at the seal cover lower part in the length of seal cover lower part.
Ear washing bulb top is provided with pore, and ear washing bulb and air inlet pipe are tightly connected.
The elbow of drain pipe is acute angle bending elbow or cross break elbow, and the bottom of elbow is a tapered mouth.
The utility model is that liquid getting device is installed on the reagent bottleneck, seal cover seals the reagent bottle bottleneck, the air inlet pipe lower surface is positioned at more than the liquid level of reagent, the straight tube lower surface of drain pipe is near the reagent bottle bottom, the extruding ear washing bulb, air inlet in the reagent bottle, reagent is extruded from drain pipe, in the safe injection experiments vessel, the control ear washing bulb can accurately be controlled the discharge of liquid drug from reagent bottle easily, be applicable to highly acid, strong basicity, severe corrosive, strong liquid reagent such as dissolving grade get liquid, contaminated environment and the reagent harm healthy having avoided reagent to spill causing to the experimenter.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of another kind of embodiment.
The specific embodiment
As shown in Figure 1, liquid getting device comprises the seal cover 3 that is provided with two axially extending bores, be separately installed with in the through hole on the air inlet pipe 2 and drain pipe 4 of both ends open, air inlet pipe 2 upper ends are sealedly connected with ear washing bulb 1, drain pipe 4 is for having the straight tube of cross break elbow 6, the bottom is a tapered mouth 7, the straight-tube portion of drain pipe 4 is inserted on the seal cover 3, drain pipe 4 is longer than the length of air inlet pipe 2 at seal cover 3 lower parts in the length of seal cover 3 lower parts, ear washing bulb 1 top is provided with pore 5, and air inlet pipe 2 and drain pipe 4 can be made by glass tube.
In the another kind of embodiment as shown in Figure 2, the elbow 6 of drain pipe 4 is acute angle bending straight tube, and the bottom is a tapered mouth 7, and all the other structures are identical with previous embodiment, do not repeat them here.
Seal cover can or install the bottle cap that valve rubber seals additional for rubber stopper, and the making of this liquid getting device is fairly simple, and plastic bottle closure, ear washing bulb, sealing gasket can be used Mold Making, and glass tube can be made by hot-working.
