Corning Narrow Mouth 25 ml Flasks with Heavy Duty Rim - Set of 12 Flasks

The Corning 4980-25 Narrow Mouth Erlenmeyer Flask is a 25 mL piece of laboratory glassware designed for general-purpose use, particularly for mixing, heating, and storing solutions. Constructed from high-quality PYREX Borosilicate Glass (Code 7740), which provides excellent resistance to heat, chemicals, and thermal shock, making it safe for use on hot plates and in heating baths. The narrow mouth feature helps reduce solvent evaporation, minimizes splash-out when swirling contents, and allows for easier sealing with stoppers or septa. Due to its robust design and flask shape (conical body and flat bottom), the 4980−25 is ideal for small-scale applications such as titrations, media preparation, heating and boiling, and storage and mixing.
