Abstract
The utility model discloses a pH test paper colorimetric disc, belonging to the field of chemistry experiment teaching equipment, and structurally comprising a disc body and colorimetric cards, wherein the rectangular disc body is provided with a plurality of colorimetric tanks, and one colorimetric card is correspondingly arranged above each colorimetric tank; and the disc body at the side surface of the colorimetric tank is further provided with a test paper tank for placing pH test paper. Compared with the prior art, the pH test paper colorimetric disc has the characteristics of reasonable design, simple structure, easy processing, convenient use, safety, cleanness, accurate color comparison and the like, and effectively improves the experimental efficiency.
Description
Technical field
The utility model relates to the chemical experiment teaching apparatus field, specifically PH test paper colorimetric disc.
Background technology
The PH test paper is that checking liquid is the instrument of acidity or alkalescence, and the student uses through regular meeting when experiment.Present using method is that the student takes test paper on the other hand, with suction pipe liquid is dripped on the test paper on the other hand, or test paper is dipped in the liquid, and test paper and the colorimetric card with variable color contrasts then, thereby judges the character of current liquid.This using method student can only contrast a kind of liquid at every turn, and in the use, liquid is easy to pollute student's finger.
Summary of the invention
Technical assignment of the present utility model is at above weak point, and a kind of rational in infrastructure, easy to use, colorimetric PH test paper colorimetric disc accurately is provided.
The technical scheme that its technical matters that solves the utility model adopts is: this colorimetric disc comprises disk body and colorimetric card, has a plurality of cells on the rectangle disk body, and each cell top correspondence is provided with a colorimetric card; Also be provided with a test paper groove of placing the PH test paper on the disk body of cell side.
The downside of described cell is the inclined-plane, and the tail end on inclined-plane is identical with the disc surfaces height.
During use, splash into different liquid in each cell, put into the PH test paper then, corresponding colorimetric card can be learnt the character of multiple liquid fast.After using up, erect disk body, the liquid in the cell promptly can flow out in cell, can clean cell very easily afterwards.
PH test paper colorimetric disc of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, clean, characteristics such as colorimetric is accurate easy to use, safe, effectively raise conventional efficient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of PH test paper colorimetric disc.
Among the figure: 1, disk body, 2, cell, 3, the test paper groove, 4, colorimetric card, 5, the inclined-plane.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
PH test paper colorimetric disc of the present utility model, its structure comprises disk body 1 and colorimetric card 4, has a plurality of cells 2 on the rectangle disk body 1, and each cell 2 top correspondence is provided with a colorimetric card 4, the downside of cell 2 is inclined-plane 5, and the tail end on inclined-plane 5 is identical with disk body 1 surface elevation; Also be provided with a test paper groove 3 of placing the PH test paper on the disk body 1 of cell 2 sides.
Its processing and fabricating of PH test paper colorimetric disc of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
