Laboratory test tube brushes: small sized brushes on the left, large sized brushes on the right.

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.

Brushes are designed for the purpose of cleaning test tubes, therefore are developed to be able to reach all corners of the glassware.[3]

Tip type Description Radial tip Round tufted tip allows for a curved brush edge, protecting the glassware from contact against the twisted metal wire handle.[4] Stainless steel wire stem radial tip Similar to radial tip brushes, but more durable and efficient in glassware cleaning.[3] Tied tip Bristles are tied together at the tip to facilitate the cleaning of tubes and bottles with narrow openings, capable of expanding at the bottom of the tube without scratching the surface.[3] Sponge tip The soft tip enables expansion and absorption of liquid, which results in more thorough cleaning of the tube and protection from scratches.[3]

It has an extra long radial bristle tip that is flexible enough to enter the narrow neck of various laboratory glassware, and fan out at the bottom of the chamber for efficient cleaning. The middle section of the metal wire handle contains short stemmed bristles that can be used to scrub along the neck of the flask.[5]
