DURAN 212161707 Narrow Neck Erlenmeyer Flask 50 mL

The DURAN 212161707 is a 50 mL narrow-neck Erlenmeyer flask, manufactured from DURAN® borosilicate glass 3.3, providing excellent chemical resistance and thermal durability. The conical design with a narrow neck reduces evaporation and splashing, while the beaded rim adds mechanical strength during handling.

This flask includes approximate printed graduations for quick volume estimation and a Retrace Code for batch traceability and quality assurance. Its uniform wall thickness allows safe and consistent heating, making it suitable for use on hot plates or in autoclaves.

Compliant with DIN ISO 1773 standards, the flask measures approximately Ø 51 mm (body diameter) × 90 mm (height) with a 22 mm neck diameter, and is fully autoclavable (~121 °C) for safe sterilization and reuse.
