Drying tube - Wikipedia

A drying tube or guard tube is a tube-like piece of apparatus used to house a disposable solid desiccant, wherein at one end the tube-like structure terminates in a ground glass joint for use in connecting the drying tube to a reaction vessel, for the purpose of keeping the vessel free of moisture.. The tube-like structure is often bent and can also widen to form a bulb/desiccant reservoir.
