Description
Technical field
The utility model belongs to chemical experimental instrument field, is related to a kind of tubular dropping funel, and especially one kind has and stirs
It mixes, the constant pressure type tubular dropping funel system of temperature control, precision measure function.
Background technique
Dropping funel is that middle school chemical experiment, college chemical experiment and high scientific research institutions carry out in scientific experiment research often
Liquid Dropping feeder can meet chemical reaction gradually by liquid material dropping into reaction system by dropping funel
It needs.In reaction experiment operating process, in order to enable reaction can be gone on smoothly, often there are temperature, drop to the material of dropwise addition
The requirement of acceleration, uniformly mixed etc., but traditional use for laboratory dropping funel is simply possible to use in single liquid or solution exists
It is added dropwise under room temperature, rate of addition is pure by rule of thumb, is unable to satisfy the requirement of more reaction conditions such as temperature, drop speed, therefore need
Improvement is made to dropping funel.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide one kind to have stirring, temperature control, essence
The multi-functional constant pressure type tubular dropping funels such as degree measurement can be realized uniform mixing, the temperature control, accurate drop of multicomponent system
Add.
To achieve the goals above, the utility model adopts the following technical solution, comprising:
Mark graduated tubular infundibular body, minim pipette, plug valve, sleeve, ground glass stopper, miniature DC motor, stirring
Bar, gate stirrer, rubber tube, thermostatic water bath are equipped with the venthole being connected with infundibular body in ground glass beyond the Great Wall, for keeping
The intracorporal pressure of funnel is identical as external pressure, realizes the smooth dropwise addition of system to be added dropwise.
Preferably, the tubular infundibular body is made of transparent glass material, and it is corrosion-resistant, convenient for the liquid in observation funnel
Planar condition.As further preferred, it is equipped with graduation mark on the infundibular body, is convenient for accurately being added dropwise, speed is added dropwise in control
Degree.
Preferably, the end of minim pipette is angle, the tip portion of angle avoids solution wall built-up convenient for solution outflow.
Preferably, the outer wall of sleeve is preferably frosting.
Preferably, plug valve is made of glass or tetrafluoroethene material, can be integrally formed with sleeve under plug valve.
Preferably, the middle and lower part of stirring rod is equipped with gate stirrer, convenient for shearing to material, realize that multiple groups are seperated
System is sufficiently mixed.
Preferably, rubber tube is heat-resistance type rubber tube, both ends are all connected with thermostatic water bath, and middle section bypasses funnel
Body controls the temperature of material to be added dropwise in infundibular body by the temperature of thermostatic water bath.
The utility model can make up for it the deficiencies in the prior art, by being equipped with agitating device in infundibular body, effectively solve
Multicomponent system causes the problem of cannot using dropping funel because being layered or settling, while because in infundibular body mark scale, energy
It is enough accurately titrated, and by the heat transfer of the rubber tube with thermostatic water bath, is conducive to the mixing of material to be added dropwise, is conducive to
The temperature for controlling object system to be added dropwise, better meets the needs of chemical reaction, and all in all, structure is simple, can be very convenient for operation
Good applicable chemical experiment and scientific research.
