What is a test tube brush and how is it used?


Answer by  bean11 (2803)

A test tube brush is a very small brush that chemists use to clean out their test tubes after they are used.

A test tube brush is a nifty device that allows you to get into that narrow space and clean it. It's just a simple device of nylon or wire bristles in a twisted wire shaft, but probably one of the smartest time saving devices invented- the kind of thinking that separates man from beasts, sort of a grandiose pipe cleaner.
