Abstract
The utility model discloses a volumetric flask, which comprises a flask body and a flask plug. The volumetric flask is characterized in that a small volumetric flask is arranged in a big volumetric flask. The disadvantage that if the traditional volumetric flask has poor constant volume and a little more solvent is added dropwise, a bottle of solution is poured away and then is prepared again is overcome through the two combination modes of the big volumetric flask and the small volumetric flask.
Description
Technical field
The utility model relates to a kind of container, and in particular, the utility model is the volumetric flask that a kind of chemical experiment is used.
Background technology
Volumetric flask is the glass apparatus of chemical laboratory configuration standard solution commonly used.Configuration during solution a very important step be exactly constant volume, know all that with the people of overcapacity bottle if constant volume is bad, dripped some solvents, this bottle solution will be outwelled reprovision so more, cause very big waste, and contaminated environment.
Summary of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, if provide a kind of when having added solvent when configuration solution constant volume, does not need to outwell solution, still can continue to dispose the novel volumetric flask of this solution.
The purpose of this utility model is that implied meaning realizes by the following technical programs:
A kind of volumetric flask, it comprises bottle (6), bottle stopper (4), described volumetric flask is characterized in that in the big volumetric flask (1) a little volumetric flask (2) or test tube being arranged.
The big volumetric flask of this volumetric flask and low capacity bottle all have two scales.During constant volume, to following of big volumetric flask graduation mark (3),, promptly be required capacity big volumetric flask constant volume little volumetric flask constant volume above low capacity bottle high scale line (5); If put during to big volumetric flask constant volume solvent because of carelessness many, just can be directly big volumetric flask constant volume above graduation mark (3), low capacity bottle constant volume below graduation mark (5), also be required capacity this moment.
Description of drawings
Figure is the structural representation of this device;
Among the figure: big volumetric flask 1 low capacity bottle 2 big volumetric flask scale 3 bottle stoppers 4 low capacity bottle scales 5
Good effect of the present utility model is:
Unpunctual to configuration solution once fixed capacity, can continue configuration, avoided the waste of solution, protection of the environment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
It comprises bottle 1, bottle 2 and bottle stopper 4, and bottle stopper 4 is bottle stoppers of bottle 1, and bottle 2 is fixed on bottle 1 inside, and the bottleneck height of bottle 2 is lower than the bottleneck height of bottle 1; Two scales 3 are arranged on the bottle 1, two scales 5 are arranged on the bottle 2, two combinations are arranged: the following scale combination of a top scale of first bottle 2 and bottle 1; It two is top scale combinations of the following scale of bottle 2 and bottle 1, and the capacity of these two combinations equates, and all equals required capacity.
Claims (2)
1. volumetric flask, it comprises bottle (6), bottle stopper (4), it is characterized in that described bottle (6) comprises a big volumetric flask (1) and the low capacity bottle (2) in big volumetric flask inside.
2. volumetric flask according to claim 1 is characterized in that, two scales are all arranged on described big volumetric flask and the low capacity bottle.
