Abstract
The utility model provides a test tube for prevent fried high temperature resistant chemistry that splits experiments, including tube body, the outside cover of tube body is equipped with the sleeve pipe of glass material, be equipped with the unilateral clearance between sleeve pipe and the tube body and be 0.5-1mm clearance, clearance intussuseption between sleeve pipe and the tube body is filled with liquid medium, tube body is equipped with the stopper with the sheathed tube open end, the stopper is unsettled in the sleeve pipe center with tube body, the asbestos gauge who forms is woven to sleeve pipe surface adhesion one deck by stone cotton yarn. The utility model has the characteristics of the transparent characteristic of test tube self had both been guaranteed to this test tube, observed the in vitro reactant in making things convenient for the experimentation, had special construction in addition, and it is even to be heated, and the part that has effectively prevented the test tube is heated lead to fried and splits, has high temperature resistantly, the third even if receive the external force test tube to suffer the damage, can not produce broken glass yet, causes the injury of experimenter.
Description
Technical field
The utility model relates to chemical experiment technique field, particularly relates to a kind of experiment equipment, specifically refers to the high temperature resistant chemical experiment test tube of a kind of anti-cracking.
Background technology
As everyone knows, a lot of chemical experiment carries out under adopting the condition of high-temperature heating, as hydrogen reducing cupric oxide, potassium permanganate high temperature oxygen production gas ... need in the chemical experiment of heating at these, bursting of test tube is common occurrence feelings, for the student of experiment, sometimes can burst accident because of what happen suddenly, nervous at heart, chemical experiment accident may be caused on the one hand, as alcolhol burner is overturned, cause fire, scald health etc., wound may be caused at heart to student on the other hand, for fear chemistry is produced and fear, thus be weary of chemistry.
Summary of the invention
The technical problems to be solved in the utility model is for the weak point existing for prior art, there is provided a kind of anti-cracking high temperature resistant chemical experiment test tube, this test tube both ensure that the transparent characteristic of test tube self, facilitate in experimentation and reaction in test tube thing is observed, in addition there is special construction, be heated evenly, what the local heating that effectively prevent test tube caused bursts, there is resistant to elevated temperatures feature, 3rd, even if damaged by external force test tube, also can not produce broken glass, cause the injury of experimenter.
Technical solution of the present utility model is, there is provided following a kind of anti-cracking high temperature resistant chemical experiment test tube, comprise test tube body, described test tube body exterior is set with the sleeve pipe of glass material, being provided with one-sided gap between described sleeve pipe and test tube body is 0.5 ~ 1mm gap, liquid medium is filled with in gap between described sleeve pipe and test tube body, the openend of described test tube body and sleeve pipe is provided with stopper, described stopper is by unsettled for test tube body in cannula center position, and described bushing outer surface adheres to the asbestos gauge that one deck is woven by asbestos yarn.
As preferably, described sleeve pipe and test tube body bottom portion are provided with supporter, and described supporter is whippy spring pad or rubber blanket.Adopt the technical program, with stopper acting in conjunction, by the unsettled setting of test tube body of inside pipe casing, make it be heated evenly.
As preferably, described test tube body tube port part is provided with projection.Adopt the technical program, effectively improve the bonding strength between test tube body and stopper.
As preferably, described stopper is provided with air-vent.Adopt the technical program, effectively prevent from heating the liquid medium water of rear inside or the oil volume that is heated and become the stopper caused greatly and be ejected and hurt sb.'s feelings.
As preferably, the diameter of described asbestos yarn is 0.5 ± 0.1mm, and the mesh length of side on asbestos gauge is the square hole of 1 ~ 2mm.Adopt the technical program, both can ensure that sleeve pipe was heated evenly, the test tube effectively preventing hot-spot from causing bursts, and utilize asbestos gauge effectively can prevent sleeve pipe just in case burst the injury to experimenter, structure is simple, easy to use simultaneously.
Adopt the beneficial effect of the technical program: this test tube both ensure that the transparent characteristic of test tube self, facilitate in experimentation and reaction in test tube thing is observed, in addition there is special construction, be heated evenly, what the local heating that effectively prevent test tube caused bursts, and has resistant to elevated temperatures feature, 3rd, even if damaged by external force test tube, also can not produce broken glass, cause the injury of experimenter.
