The sensor is the pt100 temperature sensor of stainless steel encapsulation. Traditional liquid cryostat (mainly being that water is on the rocks) is owing to there being the not enough of liquid self solidifying point, so there is the problem of temperature lower limit. The utility model discloses a metal cryostat can be so that the test system can be used for testing the lower sample of solidifying point.
Description
Technical field
The utility model relates to a kind of experimental provision, particularly the metal cold bath apparatus in a kind of kryoscopy experiment.
Background technology
It is that university chemistry is the experiment subject of standard configuration in Physical Chemistry Experiment that cryoscopic method is measured molal weight. Its core operation content is exactly to measure the freezing point of solution and the variable quantity of freezing point. At present domestic for the measurement of freezing point is to adopt to measure cooling curve and analyzed the method for cold-peace curve transition point and measure mostly. Certainly, in order to obtain test result accurately, heating and cooling are repeatedly to obtain cooling curve repeatedly conventionally, and repeatedly analysis result carries out comprehensively.
Tradition cryostat, by a large beaker, adds mixture of ice and water composition, and temperature is controlled near zero degree substantially, the control of temperature by add ice cube number realize. When measurement, in cryostat, put into Boiling tube, in Boiling tube, put into the small test tube that installs sample, in the middle of large small test tube, have one section of air insulated, play the effect of retarding heat transmission and uniform temperature. In small test tube, add thermometer measure temperature, stirring rod is used for carrying out hand operated mixing.
Some further improved on traditional cryostat is measured afterwards, made mercurial thermometer (or Beckman thermometer) into digital thermometer (or precision digital temperature differential measuring apparatus), used electric stirring in stirring instead.
Utility model content
Utility model object: technical problem to be solved in the utility model is for the deficiencies in the prior art, provides the metal cold bath apparatus in a kind of kryoscopy experiment.
In order to solve the problems of the technologies described above, the utility model provides the metal cold bath apparatus in a kind of kryoscopy experiment, comprises beaker, and described beaker outside is nested with metal cryostat cup, metal cryostat cup outside is coated with semiconductor chilling plate, and semiconductor chilling plate is provided with radiator.
In the utility model, described beaker bottom is provided with a heat insulating mattress.
In the utility model, be provided with a temperature sensor in described beaker, temperature sensor opposite side is connected to digital thermometer.
In the utility model, described metal cryostat cup lower end is provided with magnetic stir bar, and beaker inside is provided with magnetic agitation rod, and magnetic stir bar is corresponding with magnetic agitation rod.
In the utility model, between described metal cryostat cup and semiconductor chilling plate, be provided with heat-conducting layer.
In the utility model, described sensor is the Pt100 temperature sensor of stainless steel encapsulation.
Beneficial effect: 1, traditional liquid cryostat (being mainly that water is on the rocks) is owing to there being the deficiency of liquid self freezing point, so there is the problem of lowest temperature. The utility model adopts metal cryostat cup can make test macro can be used for testing the sample that freezing point is lower.
2, metal cryostat cup facilitates conjunction with semiconductors cooling piece to freeze or heats to control temperature, need not control temperature by number on the rocks again, and experimentation is continuous, can not interrupted by the rocks.
3, the additional forced air cooling heat radiation of semiconductor chilling plate, without logical recirculated water, compact conformation, convenient and reliable operation.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is done further and illustrated, above-mentioned or otherwise advantage of the present utility model will become apparent.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.
Embodiment:
As Fig. 1, the utility model comprises beaker 1, metal cryostat cup 2, semiconductor chilling plate 3, radiator 4, temperature sensor 5, digital thermometer 6, magnetic stir bar 7 and magnetic agitation rod, test sample is placed in beaker 1, beaker 1 outer ring is provided with metal cryostat 2, semiconductor chilling plate 3 and radiator 4 successively, in beaker 1, be provided with one and be communicated to outside temperature sensor 5, temperature sensor 5 other ends are connected to digital thermometer 6. Beaker 1 inside is provided with a magnetic agitation rod, and beaker 1 lower end is provided with a magnetic stir bar 7, and magnetic stir bar 7 coordinates and stirs with magnetic agitation rod.
Metal cryostat in the experiment of this kryoscopy adopts the good metal materials of heat conduction such as copper, aluminium, around seals with foaming thermal-insulating. Its advantage is to have overcome liquid cryostat (being mainly that water is on the rocks) owing to there being liquid self freezing point, so there is the problem of lowest temperature. Such design can make test macro can be used for testing the sample that freezing point is lower, and this is that traditional cryostat is not accomplished.
