Abstract
The utility model relates to a Tyndall phenomenon sight which comprises a hollow dark box (1), wherein, two observation holes (2) are arranged in the facade of the hollow dark box (1), two holes (3) for placing cuvettes are arranged on the top of the hollow dark box (1), two focus lamps (4) are respectively arranged at the left and the right sides of the hollow dark box (1), and a switch (5) and a low-voltage power supply are arranged at the bottom of the hollow dark box (1). The sight has the advantages that the light path is clear, the effect is obvious, and the operation is simple and free; the teacher can demonstrate on the dais, the observation demonstration range is larger, besides, the sight is very convenient for the students to watch one by one.
Description
Technical field
The utility model relates to education experiment equipment technical field, a kind of specifically Tyndall phenomenon peeker.
Background technology
The first segment colloid experiment of the 3rd second unit of senior chemistry, how to distinguish solution, colloid, suspension or emulsion, be to divide in theory by the size of dispersed particle, the dispersed substance particle is a solution less than 1nm's, greater than 100nm is suspension or emulsion, the disperse system of dispersed substance particle between 1nm-100nm just is colloid.
Be by " dindar experiment spy out device " in experiment, gelatin embodies and resembles with the passing through of optically focused " light path ".In the experiment, should know and see that when light beam passes through, form " path " of a light in the colloid, solution does not then have.The difference of Here it is colloid and SOLUTION PROPERTIES.
In the experiment in the past, this phenomenon is distant, and main cause is as follows: because light source is an electric torch, light intensity is not enough, causes light path unintelligible; Test used container---the beaker volume is excessive, and the teacher need hold torch on the other hand, two beakers that fill with liquid of proficiency support, because two beaker weight are heavier, it is very inconvenient to operate; Passing round for a look at all between the student can't be accomplished.
The utility model content
The purpose of this utility model is that design is a kind of can be not only convenient but also clearly observe the Tyndall phenomenon peeker of Tyndall phenomenon.
The utility model Tyndall phenomenon peeker, comprise: hollow magazine 1, the front of hollow magazine 1 have two viewports 2, and two holes 3 of placing test tube are arranged at the top of hollow magazine 1, respectively there is a spotlight 4 on the two sides, the left and right sides of hollow magazine 1, and switch 5 and low-tension supply are equipped with in the bottom of hollow magazine 1.
The advantage of the utility model Tyndall phenomenon peeker is: light path is clear, and effect is obvious, and is freely simple to operate, both can be demonstrated on the dais by the teacher, and observation demonstration scope is bigger, can be passed round for a look mutually by the student again, and is very convenient.
Description of drawings
Accompanying drawing is the structural representation of Tyndall phenomenon peeker.
Embodiment
With reference to the accompanying drawings, the Tyndall phenomenon peeker, comprise: hollow magazine 1, there are two viewports 2 in the front of hollow magazine 1, two holes 3 of placing test tube are arranged at the top of hollow magazine 1, respectively there is a spotlight 4 on the two sides, the left and right sides of hollow magazine 1, and switch 5 and low-tension supply are equipped with in the bottom of hollow magazine 1.
Claims (2)
1, a kind of Tyndall phenomenon peeker, comprise: hollow magazine (1), it is characterized in that: there are two viewports (2) in the front of hollow magazine (1), two holes (3) of placing test tube are arranged at the top of hollow magazine (1), respectively there is a spotlight (4) on the two sides, the left and right sides of hollow magazine (1), and switch (5) and low-tension supply are equipped with in the bottom of hollow magazine (1).
2, Tyndall phenomenon peeker according to claim 1 is characterized in that: spotlight (4), switch (5) are connected with lead with low-tension supply, form parallel circuit.
