Abstract
The utility model discloses a volumetric flask, comprising an elongated flask neck and a circular flask body positioned at the lower part of the flask neck and communicated with the flask neck. The volumetric flask is characterized in that an opening is arranged on the flask body, and the volumetric flask also comprises a flask plug made of anticorrosion material and matched with the opening. According to the volumetric flask, the opening is additionally arranged on the flask body, the volumetric flask is sealed by the flask plug in normal use, when the volumetric flask is cleaned, the flask plug can be removed, so that a pipette can directly enter from the opening to suck liquid at the bottom of the volumetric flask, the structure is simple, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of container, the volumetric flask that especially a kind of chemical experiment is used.
Background technology
Volumetric flask is the glass apparatus of chemical laboratory configuration standard solution commonly used, generally include bottleneck and body, in the time of when experiment, need drawing the liquid in the volumetric flask, because bottleneck is comparatively elongated, can't use the direct imbitition of liquid-transfering gun, and can only come imbitition from the mode that bottleneck inserts by transfer pipet, it is cumbersome and not accurate enough to operate.When experiment finishes needs cleaning volumetric flask, can only insert hairbrush from bottleneck and clean in addition, circular body does not reach hairbrush and can't clean.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, be convenient to draw in the volumetric flask liquid and to the volumetric flask of its cleaning operation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of volumetric flask, comprise elongated bottleneck, and the body that is positioned at the circle that described base of neck is communicated with described bottleneck, it is characterized in that, described body is provided with opening, and described volumetric flask also comprises the bottle stopper of being made by corrosion resistant material that cooperates with described opening.
Described opening has the open neck to outer lug, and described bottle stopper places on the described open neck, and during imbitition, liquid-transfering gun can enter the liquid that directly goes to draw the volumetric flask bottom from opening; During cleaning, hairbrush can be directly from then on opening insert and touch the circular body of volumetric flask and clean.
Compared with prior art, advantage of the present utility model is: add opening by the body at volumetric flask, and when normal the use, adopt bottle stopper to seal, thereby removable bottle stopper liquid-transfering gun can directly enter the liquid of drawing the volumetric flask bottom from opening during imbitition, simple in structure, easy to operate; When cleaning volumetric flask, can make hairbrush directly touch circular body and clean.
Description of drawings
Fig. 1 is the synoptic diagram of volumetric flask of the present utility model.
Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
Referring to Fig. 1, a kind of volumetric flask comprises elongated bottleneck 1, and the body 2 that is positioned at the circle that bottleneck 1 bottom is communicated with bottleneck 1.
The top of body 2 offers an opening 21, and opening 21 has the open neck 22 to outer lug, and by bottle stopper 23 sealings, this bottle stopper 23 is made by the material of corrosion resistivity on the open neck 22.
When volumetric flask normally used in experiment, bottle stopper 23 was placed on the open neck 22, and sealed open 21 prevents the liquid outflow in the volumetric flask.When liquid need is drawn in the volumetric flask in experiment, bottle stopper 23 can be taken off, liquid-transfering gun directly removes to draw the liquid of volumetric flask bottom by opening 21; When cleaning volumetric flask, also bottle stopper 23 can be taken off, hairbrush directly cleans circular body by opening 21.
The above only is preferred implementation of the present utility model; should be pointed out that for the ordinary skill in the art, do not breaking away under the principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
Claims (2)
