These Erlenmeyer flasks feature heavy-duty rims to reduce chipping, white, permanent graduations, and large marking squares. Made from high-quality borosilicate tubing with a low coefficient of expansion. Borosilicate tubing also provides uniform wall thickness resulting in the optimum balance between thermal shock resistance and mechanical strength.
