DURAN 212263903 Wide Neck Erlenmeyer Flask 300 mL

DURAN 212263903 Wide Neck Erlenmeyer Flask 300 mL

The DURAN 212263903 is a 300 mL wide-neck, flat-bottom Erlenmeyer flask made of DURAN® borosilicate glass 3.3, renowned for its high chemical resistance, durability, and low thermal expansion. Its wide neck (~50 mm OD) provides easy access for filling, pouring, cleaning, or adding solids, making it more convenient than narrow-neck flasks.

It has a flat base for stability on benches and hot plates, with an overall body diameter of ~87 mm and a height of ~156 mm. Approximate printed graduations allow quick volume estimation, while the beaded rim strengthens the neck against chipping. This flask is supplied non-sterile, without cap, typically in packs of 10 units. It complies with DIN 12380 standards for wide-neck Erlenmeyer flasks and is autoclavable (~121 °C) for safe sterilization and repeated use.
