The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of Improvement type that can accurately fall liquid holds
Measuring bottle.
The utility model is achieved through the following technical solutions：
A kind of Improvement type volumetric flask that can accurately fall liquid, including bottle and bottle stopper, the bottle upper end open, the bottle stopper
Cooperation is just mutually sealed with bottle upper end open, bottle top side is provided with leakage fluid dram, one section is provided with the leakage fluid dram
Outwardly directed draining pipe, apocenosis passage is provided with inside the bottle stopper, the import of the apocenosis passage is located at bottle stopper bottom, institute
The outlet for stating apocenosis passage is located at bottle stopper side, and after bottle stopper is just sealed with bottle upper end open and coordinated, on the bottle stopper
The outlet of apocenosis passage is placed exactly on sustained height position with the leakage fluid dram on the bottle, can be real by rotating the bottle stopper
The outlet of existing apocenosis passage is relative with leakage fluid dram to be connect or is staggered.
As the preferred embodiment of above-mentioned technical proposal, the bottle from the bottom to top be respectively body section, Bottle Neck Road and
Pass, for the pass profile in cylinder, the bottle stopper includes bottle stopper post and the bottle stopper cap located at bottle stopper top end, described
Bottle stopper post profile is the cylinder to be matched with pass inner wall shape, and the bottle stopper cap diameter is more than bottle stopper column diameter.
As the preferred embodiment of above-mentioned technical proposal, the apocenosis passage is in integrally inverted L-shaped, the apocenosis passage
Circular in cross-section, the leakage fluid dram is rounded, and the leakage fluid dram is identical with the diameter of apocenosis passage.
As the preferred embodiment of above-mentioned technical proposal, the draining pipe outer end tilts upward extension.
As the preferred embodiment of above-mentioned technical proposal, the draining pipe outer end is in shrink mouth shape.
The utility model has advantages below compared with prior art：
It is provided by the utility model it is a kind of can accurately fall liquid Improvement type volumetric flask, it is provided with discharge opeing inside bottle stopper and led to
Road, while leakage fluid dram is provided with bottle top side, when rotation bottle stopper is staggered to the outlet port of apocenosis passage with leakage fluid dram
When can the closed volumetric flask, realize turned upside down volumetric flask mix bottle in reagent purpose；When rotation bottle stopper to apocenosis passage
Outlet port is relative with leakage fluid dram can outwards to fall liquid when connecing by leakage fluid dram, simple to operate.Further, since in bottle
Draining pipe is connected with leakage fluid dram, outwards liquid, the shrink mouth shape of draining pipe outer end can be realized by draining pipe drainage
Accurately fall liquid and not spilling out into small-bore reagent bottle or buret.
Brief description of the drawings
Fig. 1 is Bottle structure schematic diagram of the present utility model.
Fig. 2 is the longitudinal section of bottle stopper of the present utility model.
Label in figure：1 bottle, 11 body sections, 12 Bottle Neck Roads, 13 passes, 14 draining pipes, 2 bottle stoppers, 21 discharge opeings are led to
Road, 22 imports, 23 outlets.
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Referring to Fig. 1, Fig. 2, present embodiment discloses a kind of Improvement type volumetric flask that can accurately fall liquid, including bottle 1 and bottle
Plug 2, the upper end open of bottle 1, bottle stopper 2 just mutually seal cooperation with the upper end open of bottle 1, and bottle 1 is respectively body from the bottom to top
Section 11, Bottle Neck Road 12 and pass 13, Bottle Neck Road 12 are provided with graduation mark, and the profile of pass 13 includes bottle in cylinder, bottle stopper 2
Stick harness and the bottle stopper cap located at bottle stopper top end, bottle stopper post profile are the cylinder to be matched with the inner wall shape of pass 13, and
Bottle stopper cap diameter is more than bottle stopper column diameter.
The top side of bottle 1 is provided with leakage fluid dram, and leakage fluid dram is rounded, is led at leakage fluid dram provided with one section of outwardly directed discharge opeing
