Abstract
The invention discloses a volumetric flask. The volumetric flask comprises volumetric flask bodies and connecting pieces. The three volumetric flask bodies are connected together through the connecting pieces, flask stoppers are arranged at the tops of the volumetric flask bodies, protecting sheaths are arranged outside the flask stoppers, sealing stoppers are arranged in the protecting sheaths, magnetic stirring mechanisms are arranged at the bottoms of the volumetric flask bodies, the sealing stoppers are ground glass stoppers, scale lines on the volumetric flask bodies are black and are arranged outside the flask bodies, and the volume of the volumetric flask is 500 ml. As the protecting sheaths are arranged outside the flask stoppers, the flask stoppers can be protected against contamination when placed on an experiment table, and then prepared solutions are protected against contamination; as the three volumetric flask bodies are connected together through the connecting pieces, convenience is brought to the situation that three repeated experiments are needed, and the stability of the small volumetric flask bodies can be improved to prevent toppling; as the magnetic stirring mechanisms are arranged at the bottoms, slightly-soluble substances can be helped to dissolve, and the concentration of the solutions in the volumetric flask bodies can be more uniform.
Description
Technical field
The present invention relates to experimental article field, specially a kind of volumetric flask.
Background technology
When volumetric flask is used for the solution of accurate formulation certain substance withdrawl syndrome, there are problems that a lot, bottle stopper easily pollutes, little
Type volumetric flask is easy to topple over, and large-scale volumetric flask is not easy to prepare solution the problems such as mix, also useful volumetric flask preparation solution when,
Material is first dissolved in small beaker by needs, the process such as ability constant volume, easily by material damage or pollution.
The content of the invention
The present invention is directed to above weak point, there is provided a kind of volumetric flask, is conveniently used in the experiment of three repetitions, stirs
Mix uniform, make the concentration mixing in volumetric flask consistent, it is to avoid the phenomenon of uneven concentration occur.
The technical solution adopted for the present invention to solve the technical problems is：A kind of volumetric flask, include capacity bottle body and
Connector, 3 capacity bottle bodies are linked together by connector, and the volumetric flask bodies top is provided with bottle stopper, institute
State, the protection sheath is internally provided with sealing plug, the bottom of the capacity bottle body is provided with
Magnetic agitation mechanism, the sealing plug are ground glass stopper.
Graduation mark on the capacity bottle body is black, is arranged at outside bottle, it is not easy to cause error, and that what is seen is more clear
Chu.
The volumetric flask is 500ml.
The invention has the beneficial effects as follows：
The present invention has beneficial effect, is provided with protection sheath, bottle stopper can be protected to be placed on experimental bench outside bottle stopper
When, it is not contaminated, and then protects matched somebody with somebody solution not to be contaminated, 3 volumetric flasks are linked together by connector, are both conveniently used for
Doing experiment needs the situation of 3 repetitions, can increase the steadiness of low capacity bottle, prevent from toppling over, and bottom is provided with magnetic agitation
Mechanism, can both help indissoluble material to be dissolved, and can make the solution concentration in volumetric flask more uniform again.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is bottle plug structure schematic diagram
In figure：1- capacity bottle bodies, 2- connectors, 3- bottle stoppers, 4- magnetic agitations mechanism, 5- protection sheaths, 6- sealing plugs；
Specific embodiment
Describe the present invention with specific embodiment below in conjunction with the accompanying drawings：
A specific embodiment of the present invention as shown is, a kind of volumetric flask includes capacity bottle body 1, described 3
Capacity bottle body 1 is linked together by connector 2, is provided with bottle stopper 3, outside the bottle stopper 3 at the top of the capacity bottle body 1
Protection sheath 5 is provided with, the protection sheath 5 is internally provided with sealing plug 6, and the bottom of the capacity bottle body 1 is provided with magnetic force and stirs
Mix mechanism 4.
Graduation mark on the capacity bottle body is black, is arranged at outside bottle.
The volumetric flask is 500ml.
When we are using the present invention, can be used together after the connection of connector 2 with three capacity bottle bodies 1, it is also possible to
It is used alone, when needing stirring, can be stirred by switching on power to magnetic agitation mechanism 4, can both help indissoluble thing
Matter is dissolved, and can make the solution concentration in volumetric flask more uniform again.Present invention design is simple, convenient and practical.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvement and modification can also be made, these improve and modify
Also should be regarded as protection scope of the present invention.
