Abstract

The utility model provides a demonstrating device for exploring the influence on the activity of an enzyme by different factors and relates to the technical field of biological experiment teaching aids. The demonstrating device is composed of an iron support, a U-shaped pipe, a syringe and a wild-mouth bottle, wherein a rubber plug is arranged on the wild-mouth bottle and the two holes are formed on the rubber plug; one hole passes through a syringe needle and a glass pipe passes through the other hole; the glass pipe is connected with the U-shaped pipe through a latex pipe; and the longer end of the U-shaped pipe is fixed on the iron support by using an iron clip. Preferably, the iron support is connected with two sets of symmetrical devices which are the same. Compared with the prior art, the demonstrating device has the obvious advantages that by utilizing a comparison device, the phenomenon is obvious through the change of the height of liquid in the U-shaped pipe and an amplification effect, so as to increase the interests of students and be good for the students to observe; and the demonstrating device is convenient to use and easy to improve and is the teaching aid which has a very good popularization value.

Description

Probe into the demonstration device of different factors to the activity influence of enzyme

Technical field

The utility model relates to a kind of Bioexperiment and uses teaching aid, is specifically to probe into the demonstration device of different factors to the activity influence of enzyme.

Background technology

The 5th chapter at biological teaching material required 1 has an inquiry experiment; Promptly probing into the influence of factors such as temperature, pH value to enzymatic activity, exciting the interest of student to life quintessence, is that the batten of test tube and ashes carries out and teaching material adopts; DeGrain, experimental error is big.

The utility model content

The purpose of the utility model is the deficiency to prior art, and a kind of demonstration device of probing into different factors to the activity influence of enzyme is provided.

The purpose of the utility model realizes through following technological means: probe into the demonstration device of different factors to the activity influence of enzyme; Be made up of iron stand, U type pipe, syringe and wide-necked bottle, be stamped plug above the said wide-necked bottle, plug is a diplopore; Syringe needle passes a hole; Glass tube passes the another one hole, and glass tube is connecting U type pipe through emulsion tube, and the long in addition end of U type pipe is fixed on the iron stand with iron clamp.

As preferably, connecting two cover same apparatus of symmetry on the said iron stand.

Compared with prior art the utlity model has following tangible advantage: utilize the compare device, particularly through the variation and the amplification of liquid height in the U type pipe, phenomenon is obvious, has increased student's interest, helps observation of students; 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. iron stands wherein, 2. iron clamp, 3.U type pipe, 4. syringe, 5. emulsion tube, 6. glass tube, 7.FeCl ₃Solution, 8. plug, 9. wide-necked bottle, 10. oxydol, 11. potato lapping liquids.

Embodiment

Below in conjunction with description of drawings the utility model is done further to describe in detail:

Originally probing into different factors to the use of the demonstration device of the activity influence of enzyme is: the liquid that in U type pipe 3, injects the band look; Adjustment highly is fixed on the iron stand 1 with iron clamp 2; Connect U type pipe 3 and glass tube 6 with emulsion tube 5; In one of them wide-necked bottle 9, add acid oxydol 10, in another one wide-necked bottle 9, add alkaline hydrogen peroxide 10; Difference is plug 8 beyond the Great Wall; In two syringes 4, add potato lapping liquid 11 and FeCl respectively ₃Solution 7.The impermeability of verifying attachment when impermeability is good, can begin the contrast experiment.Experiment not only can be carried out the influence check of pH value, can also carry out the contrast experiment that influences of temperature etc., and effect is obvious.

In a word, the utility model provides and has probed into the demonstration device of different factors to the activity influence of enzyme.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician 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.
