Abstract
A synchronic demonstrating device for a high-efficiency experiment of enzyme relates to the technical field of biological teaching aids and comprises an ear washing ball, a Y-shaped tube, a branched test tube and an ordinary funnel, wherein the ear washing ball is inserted into the Y-shaped tube, the two openings at the bottom of the Y-shaped tube are connected with a glass tube by a latex tube, the glass tube is inserted into a rubber plug, and the rubber plug is inserted into the branched test tube. A branch opening of the branched test tube is connected with a tubule opening of the ordinary funnel by the latex tube. A beaker which contains incenses is arranged at the bottom of the device and the burning incenses have the same length and the same distance with the ordinary funnel. Compared with the prior art, the synchronic demonstrating device has the following advantages: the ear washing ball is filled with hydrogen peroxide, one branched test tube is filled with enzyme (i.e. manganese dioxide), the time and volume of dropped material are the same, so that the device is beneficial for students to observe, meets the requirements for synchronization and facilitates comparison with obvious phenomenon. The device is easy to use and easy to improve, so that the device is a teaching aid with popularization value.
Description
Technical field
The utility model relates to a kind of biological teaching aid, learning aid, is that the high efficiency of enzyme is tested synchronous apparatus for demonstrating specifically.
Background technology
In bioconversion medium, need the effect of demonstration enzyme in chemical reaction, wherein need to demonstrate the high efficiency of enzyme, how to allow the student observe in contrast, what teaching material adopted is the method for demonstrating respectively, and demonstration lacks comparative like this, effect is not fine, does not also have special apparatus for demonstrating at present.
The utility model content
The purpose of this utility model is at the deficiency that does not now have special apparatus for demonstrating, provides a kind of high efficiency of enzyme to test synchronous apparatus for demonstrating.
The purpose of this utility model realizes by following technological means: the high efficiency of enzyme is tested synchronous apparatus for demonstrating, prop up test tube and common funnel is formed by ear washing bulb, Y tube, tool, ear washing bulb stretches in the Y tube, two mouths connect glass tube by emulsion tube below the Y tube, glass tube inserts rubber plug, and the rubber plug plug props up on the test tube at tool.
Described tool props up the test tube tool and props up mouthful the tubule mouth of place by emulsion tube and common funnel and be connected.
The following of device also has one to hold fragrant beaker, and the length of the perfume (or spice) that is firing is identical, and the distance of the common funnel of distance is identical.
Compared with prior art the utlity model has following tangible advantage: hold hydrogen peroxide in the ear washing bulb, one of them tool props up test tube and adds enzyme (as manganese dioxide), and the time that drips medicine is identical with consumption, be convenient to observation of students, satisfied synchronous requirement, be convenient to contrast, phenomenon is obvious.Easy to use, be easy to improve, be a kind of teaching aid that promotional value is arranged very much.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
1. ear washing bulbs wherein, 2.Y shape pipe, 3. emulsion tube, 4. rubber plug, 5. tool props up test tube, 6. manganese dioxide, 7. common funnel, 8. perfume (or spice), 9. beaker.
Embodiment
Below in conjunction with description of drawings the utility model is described in further detail:
The use that the high efficiency of this enzyme is tested synchronous apparatus for demonstrating is: assemble instrument, prop up to wherein a brace and add enzyme (as manganese dioxide 6), ignition incense 8 and the height unanimity of regulating two perfume (or spice) 8 in the test tube 5.Draw certain density superoxol with ear washing bulb 1, be close to Y tube 2 and add solution, at this moment can observe 8 which burning earlier of two perfume (or spice), thereby verified the high efficiency of the catalytic action of enzyme.
In a word, the utility model provides the high efficiency of enzyme to test synchronous apparatus for demonstrating.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
