DURAN 212266309 Wide Neck Erlenmeyer Flask 2000 mL

DURAN 212266309 Wide Neck Erlenmeyer Flask 2000 mL

The DURAN 212266309 is a 2,000 mL wide-neck Erlenmeyer flask manufactured from DURAN® borosilicate glass 3.3 (Type I / neutral glass), renowned for its excellent chemical resistance and low thermal expansion. Its wide-mouth design (~72 mm OD) makes it easier to add solids, insert large pipettes, pour liquids, and clean thoroughly, while the flat base (~153 mm) provides excellent stability on laboratory benches and heating surfaces. Measuring approximately 276 mm in height, this flask is ideal for medium-to-large scale laboratory applications.

Key design elements include a reinforced beaded rim for durability, approximate printed graduations for quick volume estimation, and uniform wall thickness to enhance resistance to thermal stress. Each flask carries a Retrace Code for batch identification, ensuring full traceability and quality assurance. The product meets DIN ISO 24450 standards, is fully autoclavable at ~121 °C, and is supplied non-sterile, without cap.
