Abstract
The utility model provides a special combined dropper for a chemical laboratory, which belongs to a special appliance for the chemical laboratory and comprises a rubber ball bag and a pointed-opening glass tube, wherein an annular inwards-concave limiting groove is arranged at the front part of the pointed-opening glass tube, a fixed sleeve at the rear end part of a suction nozzle is fixed in the limiting groove in a limiting way, and the suction nozzle is particularly an elbow suction nozzle. Compared with the prior art, the special combined dropper has the following characteristics: the design is reasonable, the structure is simple, the using is convenient, the taking accuracy is high, the operation is convenient and quick and the quantifying is accurate; in addition, the accuracy of experimental results and the smooth proceeding of chemical experiments can be ensured.
Description
Technical field
The utility model relates to the chemical laboratory special equipment, a kind of specifically laboratory special combination dropper.
Background technology
In the chemistry teaching of school, often need do experiment and cooperate the student to understand at present, dropper then is the common equipment that often uses in chemistry laboratory, and microsampling has become the key of experimental result accuracy.The dropper structure of prior art is very simple, a rubber sacculus directly is enclosed within on glass or the plastic dropper main body exactly, the downward end of dropper is the suction nozzle that diminishes gradually, in the time of use is sacculus glue head to be clutched the discharge section air with hand earlier, be drawn onto in the dropper main body with the liquid of suction nozzle again needs, but such sampling operation process is slower, the work of incompatibility great amount of conventional, and also precision is poor, liquid in bottle or the container is often inhaled unclean, influences the accuracy of experimental result.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of chemical laboratory special combination dropper simple in structure, easy to use is provided.
The technical solution of the utility model realizes in the following manner, this chemical laboratory special combination dropper, its structure comprises rubber sacculus, tip glass tube, described tip glass tube front portion has an annular indent stopper slot, the fixed cover of spacing fixedly suction nozzle rearward end in this stopper slot, described suction nozzle is the elbow suction nozzle.
Described tip glass tube is marked with scale.
Described elbow suction nozzle adopts elastoplast to make.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that medical test anti-clogging dropper of the present utility model has is simple in structure, easy to use, reasonable in design, be skillfully constructed, can select whether to install the elbow suction nozzle of tip glass tube bottom according to actual needs, the convenient chemicals of drawing, take the accuracy height, convenient to operation, quantitatively accurately, suction nozzle is arranged to bending, dropper is blotted the liquid in the container only fully, guarantee the accuracy of experimental result, benefit carrying out smoothly of chemical experiment.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, sacculus, 2, tip glass tube, 3, stopper slot, 4, fixed cover, 5, scale, 6, suction nozzle.
The specific embodiment
Below in conjunction with accompanying drawing chemical laboratory special combination dropper of the present utility model is done following detailed description the in detail.
As shown in Figure 1, this chemical laboratory special combination dropper, its structure comprises rubber sacculus 1, tip glass tube 2, described tip glass tube 2 front portions have an annular indent stopper slot 3, the fixed cover 4 of spacing fixedly suction nozzle 6 rearward end in this stopper slot 3, described suction nozzle 6 is the elbow suction nozzle.
Described tip glass tube 2 is marked with scale 5, and convenient the absorption observed; This elbow suction nozzle 6 adopts elastoplast to make, and so just can make things convenient for it to be placed in the stopper slot 3, makes this dropper will treat that experimental liquid blots only fully, guarantees the accuracy of experimental result, benefits carrying out smoothly of chemical experiment.
