It should be noted that the baffle 130 is disposed in the accommodating groove 111 and fixedly connected to the base 110, the baffle 130 partitions the accommodating groove 111 into a first cavity 112 and a second cavity 113, and the height of the baffle 130 is lower than the height of the sidewall of the accommodating groove 111, so that the first cavity 112 is communicated with the second cavity 113. When the viewing cover 120 is placed on the base 110, the first cavity 112 communicates with the second cavity 113 through a gap between the upper side of the barrier 130 and the viewing cover 120. The base 110 further defines an air inlet hole 114 and an air outlet hole 115, wherein the air inlet hole 114 is communicated with the first cavity 112, and the air outlet hole 115 is communicated with the second cavity 113. The inlet hole 114 is used for supplying a gaseous fluid into the first cavity 112, so that the gaseous fluid is liquefied or solidified in the first cavity 112 to form a liquid fluid or a crystal, and during the process, an experimenter can observe the liquefaction and solidification process of the low-temperature fluid in the first cavity 112 under a controlled temperature through observing the cover plate 120.

Electric heating wires (not shown) are wound outside the air inlet pipe 150 and the air outlet pipe 160, and are used for heating the air inlet pipe 150 and the air outlet pipe 160 so as to prevent pipeline blockage caused by condensation of gaseous fluid in the air inlet pipe 150 and the air outlet pipe 160.
In this embodiment, intake pipe 150 is the polytetrafluoroethylene tubule, its coefficient of thermal conductivity is lower, can reduce the heat that the external lateral wall through intake pipe 150 leaks into base 110, also can prevent to lead to gaseous condition emergence of liquefaction in advance in intake pipe 150 because self temperature is low, and thinner pipeline can promote the air flow resistance, reduce gaseous fluid's flow, make gaseous fluid's liquefaction process slowly controllable, prevent the condition emergence of the instantaneous surge of the interior pressure of storehouse that the flow is instantaneous too big to cause, avoid gaseous fluid's liquefaction volume too much and produce the potential safety hazard.
