Abstract
The utility model relates to a test tube which comprises a big test tube (1), a big test tube plug (11), a small test tube (2) and a small test tube plug (21), wherein the bottom of the small test tube (2) is located at the middle of the big test tube (1); connection holes (3) are arranged at the bottom of the small test tube (2) and the middle of the big test tube (1); and the two connection holes (3) are connected by a control valve (4). Before an experiment, the control valve (4) is closed, and the teacher adds the reaction liquid into the small test tube (2) and the big test tube (1) respectively, so that the two reactants are separated from each other; and in a demonstrative experiment, the control valve (4) is opened, and the reaction liquid in the small test tube (2) enters the big test tube (1), so that the reactants are mixed for the demonstrative experiment. Therefore, the teacher only needs to carry the test tube instead of many instruments and drugs, thereby saving time and labor and bringing much convenience to use.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, is specifically related to the test tube that a kind of chemical experiment is used.
Background technology
At present middle school chemical experiment is more, and test tube is an instrument commonly used in the middle school chemical experiment, and existing test tube can only a kind of medicine of splendid attire before experiment; Usually use way to be: the teacher is at the on-the-spot reactant that in test tube, adds of experiment; Carry out lecture experiment then, the teacher need be with number of chemical laboratory apparatus and medicine like this, wastes time and energy; Especially carry out energetically under the miniature test situation at present education circle, more need be with a lot of instruments and medicine.
The utility model content
The purpose of the utility model is the deficiency that exists to existing test tube, and the test tube that has two bodys on a kind of is provided.
The purpose of the utility model realizes through following technological means: comprise Boiling tube, Boiling tube plug, small test tube, lab scale pipe close; The small test tube bottom is positioned at the Boiling tube medium position; Small test tube bottom and Boiling tube middle part are provided with intercommunicating pore, connect two intercommunicating pores by control valve.
Compared with prior art the utlity model has following tangible advantage: closed control valve before the experiment; The teacher adds reactant liquor respectively in Boiling tube and the small test tube; Make two reactants isolated each other, open control valve during lecture experiment, the reactant liquor of small test tube gets in the Boiling tube; Make reactant mix lecture experiment.Therefore the teacher only need carry test tube and gets final product, and has saved many instruments and medicine, and is time saving and energy saving, uses very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1-Boiling tube, 11-Boiling tube plug, 2-small test tube, 21 lab scale pipe closes, 3-intercommunicating pore, 4-control valve.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is done further to describe in detail:
Test tube as shown in Figure 1 comprises Boiling tube 1, Boiling tube plug 11, small test tube 2, lab scale pipe close 21, and small test tube 2 bottoms are positioned at Boiling tube 1 medium position, and small test tube 2 bottoms and Boiling tube 1 middle part are provided with intercommunicating pore 3, connects two intercommunicating pores 3 by control valve 4.
The method for using of this test tube: closed control valve 4 before the experiment, the teacher adds reactant liquor respectively in small test tube 2, the Boiling tube 1, makes two reactants isolated each other; Open control valve 4 during lecture experiment; The reactant liquor of small test tube 2 gets in the Boiling tube 1, makes reactant mix lecture experiment.
In a word, the utility model provides a kind of test tube time saving and energy saving, easy to use.The above; Be merely a part of specific embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
