Description
Technical field
This utility model relates to laboratory paraphernalia and manufactures field, is specifically related to the test tube that can lower the temperature.
Background technology
Test tube, also known as glass tubing, is the glass apparatus that chemical laboratory is conventional, serves as the reaction vessel of a small amount of reagent,
Use when room temperature or heating.Find during laboratory technician is actually used, when the reagent that heating is the most sensitive to temperature,
All it is difficult to control to, often occurs that temperature is too high, cause reagent to cross fast response, cause the failure of experiment.Then, how to add at test tube
During heat, it is to avoid invisible spectro temperature is too high becomes urgent problem.
Utility model content
This utility model is intended to provide a kind of test tube lowered the temperature, and can not lower the temperature and leads solving test tube of the prior art
The problem of the failure of an experiment caused.
The test tube lowered the temperature in this programme, including inner and outer tubes, its inner tube is socketed in described outer tube, and in inner tube
And be filled with between outer tube can the glassy layer of heat conduction, also include arm group, if being provided around at outer wall of inner tube in described glassy layer
Dry circle cooling tube, cooling tube includes liquid feeding end and liquid outlet, and described liquid outlet connects the column jecket being positioned at glassy layer, and column jecket
Axis parallel with the axis of inner tube；Described arm group includes feed tube and drain pipe, its feed tube and described liquid feeding end phase
Even, described drain pipe is connected with column jecket.
The operation principle of this programme and beneficial effect thereof: utilize the fall being passed through flowing in cooling tube, column jecket and arm group
Temperature agent, due to the second law of thermodynamics, high temperature reagent can transfer heat to the glassy layer of low temperature, and glassy layer is many by reagent
Waste heat amount is taken away, and the heat that oneself absorbs can be passed to cooling agent by glassy layer rapidly simultaneously, and the cooling agent flowed then can
Heat is led away so that the temperature of glassy layer reduces, and then reduces the reaction temperature of reagent.Use this test tube, can be effective
Control the reaction temperature of reagent, it is to avoid because reaction temperature is too high, the reagent reacting the failure of an experiment caused.
Further, described feed tube and liquid feeding end, drain pipe are with column jecket and threaded.Due in use,
Feed tube or drain pipe easily damage, if not taking threaded connection, feed tube and drain pipe after damage just cannot be more
Changing, cause cannot using of this test tube, the test tube the most more renewed could use, and increases experimental cost；But by screw thread even
Connect in succession, after damaging occur in feed tube or drain pipe pole, replaceable feed tube or drain pipe, reduce experimental cost.
Further, the outer wall of described feed tube and drain pipe is equipped with a circle anti-slip veins.Increase feed tube and drain pipe
The roughness of outer wall, and then improve laboratory technician and twist the frictional force of feed tube and drain pipe, it is to avoid when laboratory technician twists
Skidding, reduce the difficulty that feed tube takes off from column jecket from liquid feeding end, drain pipe.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of the test tube that this utility model can be lowered the temperature.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: arm group 1, column jecket 2, outer tube 3, cooling tube 4, inner tube 5.
Embodiment is the most as shown in Figure 1: the test tube that can lower the temperature includes that wall thickness is inner tube 5 and the outer tube 3 of 0.9mm, its
Inner tube 5 is socketed in outer tube 3, and there is the gap that spacing is 1.2mm between inner tube 5 and outer tube 3；And fill out between inner tube 5 and outer tube 3
Be filled with can the glassy layer of heat conduction, 12 circle cooling tubes 4 being provided around in glassy layer on the outer wall of inner tube 5, and adjacent cold
But the spacing of pipe 4 is 8mm.Its cooling tube 4 includes liquid feeding end, liquid outlet and body, a diameter of 0.5mm of its body, and goes out
Liquid end connects the column jecket 2 having a diameter of 0.5mm being positioned at glassy layer, and the axis of column jecket 2 is paralleled with the axis of inner tube 5.
And connect on the outer wall on outer tube 3 top and have one group of arm group 1, include an a diameter of 0.5mm in this arm group 1
Feed tube and diameter the most side by side be also the drain pipe of 0.5mm, its feed tube is connected with liquid feeding end screw thread, and column jecket
2 are connected with drain pipe screw thread, are equipped with a circle anti-slip veins on the outer wall of feed tube and drain pipe simultaneously.
Utilize the cooling agent being passed through flowing in cooling tube 4, column jecket 2 and arm group 1, due to the second law of thermodynamics, high
Temperature reagent can transfer heat to the glassy layer of low temperature, and the waste heat of reagent is taken away by glassy layer, and glassy layer can be by simultaneously
The heat oneself absorbed passes to cooling agent rapidly, and heat then can be led away by the cooling agent flowed so that the temperature of glassy layer
Degree reduces, and then reduces the reaction temperature of reagent.Use this test tube, can effectively control the reaction temperature of reagent, it is to avoid because of
Reagent reacting the failure of an experiment that is too high for reaction temperature, that cause.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic is at this
Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from this utility model structure
Under, it is also possible to making some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without impact
The effect of this utility model enforcement and practical applicability.The protection domain that this application claims should be with the content of its claim
Being as the criterion, the detailed description of the invention in description etc. records the content that may be used for explaining claim.
