Abstract (en)
[origin: EP0235778A2] This invention concerns a method for maintaining constant the wetted surface of a test-tube (1) immersed in a thermally active liquid, as well as the device for carrying-out said method, especially suited to maintain constant and reproducible the thermal conditions of the test-tube (1) during measurement of gas adsorption. Such method comprises the steps of : covering at least part of the external surface of the test tube (1) with a porous material to form a collar (7) which can be impregnated by capillary action with the liquid; immersing the test tube (1) at least partially so that the level of the liquid in a container is between the upper and lower levels of the porous collar (7); replenishing the container with the same liquid so that the level is maintained between the stated limits.
