This easy to use cleaning brush is great for beakers and other wide-mouthed glassware, as well as narrow mouth and wide bottom glassware. -- So basically – just about ever piece of common lab glassware you can think of. It will not break, chip or scratch. Simply fill the glass to be cleaned with hot or cold water, bend the brush to conform to the shape of the glass, insert, rotate, and clean. Only having your students do it could be easier!
