Test tube brush

A test tube brush or spout brush is a brush used for cleaning test tubes and narrow mouth laboratory glassware,[1] such as graduated cylinders, burettes, and Erlenmeyer flasks. It is composed of nylon, synthetic, or animal fur bristles of various diameters lined against a rather sturdy wire handle with a looped end for hanging. The wire can be made from a wide range of metals, such as aluminium, bronze, beryllium, copper, and brass.[2] FDA grade brushes are designed to be resistant to acid and other corrosive chemicals, including aromatic and aliphatic hydrocarbons, ketones, ethyl acetate esters, and trichloroethylene.
