Abstract
This utility model provides a kind of device for measuring volumetric solution weight, including base and the pole being installed vertically on base, pole is provided with the burette clamp for fixing burette, it is characterized in that, the side of described base be provided with protrude from susceptor surface for the weighing cell weighed, this weighing cell is arranged at the underface of burette, and the opposite side of described base is provided with controller, and this controller includes display and function button；Described controller and weighing cell are electrical connection.The quality of trickle when this practicality can immediately arrive at titration, is saved and calculates quality by density or carried out the link tested by another balance.
Description
[technical field]
The present invention relates to experimental provision field, particularly relate to a kind of device for measuring volumetric solution weight.
[background technology]
Burette is used to accurately release the volumetric apparatus of Uncertainty liquid, is a kind of common experimental apparatus.Titration
Pipe is divided into base buret and acid buret.The former is for measuring the liquid reagent having corrosion function to glass tubing；The latter uses
In measuring the liquid that rubber is had corrosion function.The color of acid buret generally redness, lower end is a glass piston, opens
Piston, liquid i.e. oozes in pipe.The color of base buret generally blueness, lower end rubber tube connects one with point mouth
Cuvette.Rubber tube is built with a glass ball.With left hand thumb and forefinger lightly toward while outside extruding glass bead
The rubber tube in face, forms a gap in making pipe, and liquid i.e. oozes from dropper.
But, according to the principle of burette, burette can only obtain the volume of trickle, trickle to be wondered
Quality, then must be known by the density of trickle, is calculated by density and learns.This has certain inconvenience in practical operation,
Especially in the fields such as medicine, food, cosmetics, it is more the liquid adding extra fine quality, rather than volume, and some
The density of liquid also can change along with the change of environmental condition.Therefore, in this kind of experimentation, it is also very desirable to Ke Yizhi
Connect a kind of device obtaining trickle quality.
[summary of the invention]
In order to solve the problems referred to above of the prior art, this utility model provides one can directly measure titration liquid
The device of quality.
The technical solution of the utility model is:
A kind of device for measuring volumetric solution weight, including base and the pole being installed vertically on base, pole is pacified
Equipped with the burette clamp for fixing burette, it is characterised in that the side of described base is provided with and protrudes from susceptor surface
For the weighing cell weighed, this weighing cell is arranged at the underface of burette, and the opposite side of described base is provided with control
Device, this controller includes display and function button；Described controller and weighing cell are electrical connection.Weighing cell can be measured
The quality of physics placed thereon and mass change, and then on the display of opposite side, directly display mass, save
Calculate quality by density or carried out the process tested by another balance.
Concrete, above-mentioned weighing cell includes horizontal articles holding table and is arranged at the load cell below horizontal articles holding table.
Concrete, above-mentioned horizontal articles holding table exceeds base 0.5-2 centimetre.Horizontal articles holding table must depart from base, it is impossible to
Including burette and the weighing of interior liquid thereof, otherwise total quality is not changed in before and after titration, but again have to
Stable, it is impossible to make beaker or other experimental apparatus place shakiness.
Concrete, the upper surface of above-mentioned horizontal articles holding table is circular.
Concrete, above-mentioned base is additionally provided with route protection shell in order to protect the line between controller and weighing cell
Road.
This utility model has a following useful technique effect: the matter of trickle when this practicality can immediately arrive at titration
Amount, is saved and calculates quality by density or carried out the link tested by another balance；This utility structure is simple, function
Stable, practical, being particularly suited for medicine, food, cosmetics etc. needs the experiment of adding liquid in mass ratio.

[detailed description of the invention]
Below in conjunction with specific embodiment, the present invention is described further.
Embodiment provided below also is not used to limit the scope that this utility model is contained, and described step is the most not
It is to limit its execution sequence.Those skilled in the art combine existing common knowledge and are the present invention conspicuously improved,
Also within falling into the protection domain of application claims.
Embodiment
A kind of device for measuring volumetric solution weight, as depicted in figs. 1 and 2, including base 1 be installed vertically on the end

Be equipped with protrude from base 1 surface for the weighing cell 6 weighed, this weighing cell 6 is arranged at the underface of burette 4, institute
The opposite side stating base 1 is provided with controller 7, and this controller includes display 701 and function button 702；Described controller 7 He
Weighing cell 6 is electrical connection.Weighing cell 6 can measure quality and the mass change of physics placed thereon, Jin Er
Directly display mass on the display of opposite side, save and calculate quality by density or surveyed by another balance
The process of examination.
Concrete, above-mentioned weighing cell 6 includes horizontal articles holding table and is arranged at the load cell below horizontal articles holding table.
Concrete, above-mentioned horizontal articles holding table exceeds the height of base 1 and is 0.5-2 centimetre.Horizontal articles holding table must and base
Depart from, it is impossible to including burette and the weighing of interior liquid thereof, otherwise total quality is not changed in before and after titration, but
Have to stablize again, it is impossible to make beaker or other experimental apparatus place shakiness.
Concrete, the upper surface of above-mentioned horizontal articles holding table is circular.
Concrete, above-mentioned base is additionally provided with route protection shell 8 in order to protect between controller 7 and weighing cell 6
Circuit.
