High borosilicate glass construction for safety and long life Made from high borosilicate glass for chemical purity and mechanical stability. Thick walls and a reinforced bottom increase resistance to chips and breakage, extending usable life. Reliable chemical compatibility Water, acid and alkali resistances meet international standards, so the flask performs predictably with common laboratory reagents. Suitable for routine handling of aqueous, acidic, and basic solutions without premature degradation. Accurate, easy liquid measurement Clear, graduated markings provide visible, reliable volume readings to help you measure and transfer liquids efficiently. The Erlenmeyer shape aids mixing and minimizes splashing when swirling or stirring. Practical benefits that solve common lab problems Reduces waste and repeat work by offering durable glassware that maintains clarity and graduations over time. Minimizes downtime and replacement costs thanks to the thicker wall and bottom construction. Improves workflow by combining measurement and mixing in one stable vessel. Typical applications Titration and reagent preparation: measure and mix solutions with clear graduations and a stable base for controlled pouring and swirling. Sample preparation and storage: compatible with routine aqueous, acidic, and basic samples where chemical resistance and clarity are required. Teaching and demonstration labs: durable construction and visible scales make these flasks well suited for repeated student use. Materials and performance summary Material: High borosilicate glass.
