This is a type of laboratory vessel with a cylindrical shape. Traditional test tubes are made of glass with a tube shape that is freely open on one side and a closed round bottom on the other. One type of test tube is tubes that end with a long conical bottom, which makes it easier to collect small amounts of substances at the bottom of the tube. Test-tube flasks are another, rather distinctive type of test-tube. Test-tube flasks have a ground end, which allows them to be used in vacuum distillation and allows them to be sealed tightly with a stopper. Test-tube flasks may also have a volume scale on the wall, which makes it easier to work with such a flask. Special purpose test tubes are also found in various types of laboratories. Such test tubes include centrifuge test tubes - which usually have much thicker walls than traditional test tubes or test tubes designed for use under increased pressure. In addition to traditional glass tubes, tubes made of plastic are widely used in laboratories. Plastic tubes are usually used as disposable tubes.
