DURAN 217215408 Narrow Mouth Beaded Rim 1000 mL

DURAN 217215408 Narrow Mouth Beaded Rim 1000 mL

The DURAN 217215408 is a 1,000 mL round-bottom flask made of premium DURAN® borosilicate glass 3.3. Designed with a narrow mouth and reinforced beaded rim, this flask is ideal for laboratory applications that require uniform heating, such as distillation, reflux, or chemical reactions.

Its round-bottom profile promotes even heat distribution, reducing thermal stress and improving mixing during processes. The narrow neck with beaded rim enhances mechanical strength, minimizing breakage risks during handling or cleaning. Manufactured to DIN ISO 1773 standards, the flask is also USP / EP / JP compliant and autoclavable (~121 °C), supporting both safety and reusability.
