The Premium Borosilicate Glass 3.3 Wide-Mouth Erlenmeyer Flask is an essential laboratory vessel designed to offer maximum convenience and reliability for chemical synthesis, biological culture, and volumetric titrations. Characterized by its conical body, flat base, and a flared wide neck, this flask provides a significantly larger opening compared to standard narrow-neck flasks. This architectural improvement allows for effortless solid reactant addition, easier washing, and robust assembly of reflux and distillation systems.

Molded from heavy-wall, premium-grade Boro 3.3 glass, the flask is fully autoclavable and highly stable against thermal stress. Its high-contrast white ceramic graduations are heat-fused onto the glass surface, ensuring they remain permanent and legible even after repeated chemical cleaning. The conical shape not only provides a highly stable center of gravity but also prevents liquid from splashing out during manual swirl mixing, providing a safe and highly professional experience for research institutes, universities, and industrial laboratories.

Integrated Rounded Flared Neck: Features a beautifully flared neck with a polished, thick-walled rim. The integrated molding ensures exceptionally smooth liquid pouring while significantly facilitating the insertion of solid reactants, stoppers, and stirring tools.

Ultra-Smooth Glazed Surface: The flask is crafted with a high-clarity, seamless outer and inner surface. Free of bubbles or tactile protrusions, this flawless surface finish ensures easy washing and sterilization.

Broad & Perfectly Flat Base: Designed with a wide, symmetrical, and flat bottom that lowers the center of gravity. This ensures solid, vibration-free placement on laboratory hotplates, wire gauzes, and benches.

Premium Borosilicate Glass 3.3: Offers outstanding chemical durability against corrosive reagents, acids, and alkalis. Its exceptionally low thermal expansion coefficient makes it highly resistant to extreme temperatures and thermal shock, allowing safe direct-fire heating.

Reduced Solvent Evaporation: The conical geometry effectively minimizes the evaporation of volatile substances during heating or storage, while remaining highly compatible with distillation, reflux, and synthesis apparatus.
