DURAN 212265407 Wide Neck Erlenmeyer Flask 1000 mL

DURAN 212265407 Wide Neck Erlenmeyer Flask 1000 mL

The DURAN 212265407 is a 1,000 mL wide-neck Erlenmeyer flask made from DURAN® borosilicate glass 3.3, renowned for its high chemical resistance, low thermal expansion, and long-term durability. Designed for versatile laboratory use, the wide-neck opening (~50 mm OD) allows easy filling with solids, efficient pouring of liquids, and simplified cleaning compared to narrow-neck models.

This flask features a flat bottom for stability, a reinforced beaded rim for enhanced resistance to chipping, and printed graduation marks for quick volume estimation. It complies with DIN ISO 1773 standards, is supplied without a cap (non-sterile), and is autoclavable at ~121 °C for safe sterilization and repeated use.
