DURAN 217713903 Culture Flask 300 mL

DURAN 217713903 Culture Flask 300 mL (Erlenmeyer, Straight Neck)

The DURAN 217713903 (also listed as 4AJ-9010475) is a 300 mL Erlenmeyer culture flask with a straight neck designed for use with metal caps. Constructed from DURAN® borosilicate glass 3.3 (Type I, neutral glass), it offers excellent chemical resistance, low thermal expansion, and reliable performance under repeated heating and sterilization.

Its Erlenmeyer geometry promotes efficient mixing, swirling, and aeration while minimizing the risk of spillage. The straight-neck opening (≈ 38 mm OD) ensures compatibility with flat or metal sealing caps. Supplied in packs of 10 units, this flask is durable, reusable, and well suited for microbiology, tissue culture, and general laboratory workflows.
