Lab Borosilicate 250mm Gas Drying Tower

Gas drying tower is a device that utilizes special adsorption materials to adsorb and dehumidify moisture in the air. The gas passes downward in the drying tower and passes through the adsorbent material, and the moisture will be adsorbed into the material, thus drying the air. When the adsorption material reaches saturation, it needs to be regenerated by methods such as heating and/or depressurization to release the adsorbed moisture.

Before use, the instrument should be cleaned and dried, and a small amount of glass wool should be filled from the top opening to the girdle of the container first (to prevent the desiccant from falling into the base), then add desiccant (e.g., anhydrous calcium chloride, color-changing silica gel, etc.) to the container and cover the top with a layer of glass wool again. A layer of piston grease is applied to the container stopper, which is inserted into the mouth of the container and rotated until it is clear before the whole thing is installed. According to the need, it can be placed in the position where the drying of the gas needs to be controlled (usually behind the gas washing bottle), when the gas enters from the lower branch pipe and passes through the desiccant, and then discharged through the upper branch pipe, so as to achieve the purpose of drying the gas. If a single drying tower can not meet the drying requirements, two or three drying towers can be used at the same time, connecting different kinds of desiccant for multiple drying, which can improve the drying efficiency.
