Hybex™ Erlenmeyer Flasks are manufactured from high-quality, borosilicate 3.3 glass. A low coefficient of thermal expansion (3.3), provides temperature resistance that is far superior to that of standard lab glass (or soda lime glass). Hybex glass is designed to withstand high temperatures, making them ideal for shaking applications, media preparation, and long-term storage.
The standard erlenmeyer flasks have permanent, white enamel graduations for volume measurement and a white identification box for marking or coding.
