DURAN 212272402 Wide Neck Erlenmeyer Flask 100 mL

DURAN 212272402 Wide Neck Erlenmeyer Flask 100 mL

The DURAN 212272402 is a 100 mL Super Duty Erlenmeyer flask with a wide neck, designed to combine durability, safety, and ease of use in laboratory settings. Manufactured from premium borosilicate glass 3.3, it offers excellent chemical resistance and very low thermal expansion, ensuring reliable performance during heating, mixing, or sterilization.

The Super Duty construction incorporates a reinforced rim and thicker walls, providing greater mechanical strength and resistance to breakage compared to standard Erlenmeyer flasks. This makes it suitable for intensive use in teaching, research, and industrial laboratories.

It features approximate white printed graduations that allow quick volume estimation and a fired-on white ceramic labelling field for permanent, durable sample identification. The wide-neck design improves accessibility, making it easier to add solids, pour liquids, or clean the flask efficiently.

Fully autoclavable at ~121 °C, the DURAN 212272402 complies with international standards, ensuring safety and reliability for routine and demanding laboratory applications.
