glass tube
Transparent cylindrical vessel
A glass tube is a hollow cylinder of glass, typically used in laboratory settings for containing, transferring, or heating liquids and gases.
Test tubes, pipettes, and thermometers are common examples.
Glass tubes also appear in neon signs, where electrified gas glows inside them, and in older electronics as vacuum tubes.
