Premium Borosilicate Glass Round Bottom Flask – High-Vacuum Heavy-Wall Reaction Vessel

Optimize your chemical synthesis and distillation setups with our professional-grade Glass Round Bottom Flask. Masterfully crafted from high-purity borosilicate glass, this essential reaction vessel features a uniform, heavy-wall thickness specifically engineered to distribute thermal and mechanical stress evenly across its spherical surface. This classic design makes it the industry standard for high-vacuum applications, boiling, and intensive organic chemistry reactions.

Key Applications:

• Distillation & Evaporation: The foundational component for heating mixtures in standard distillation setups, fractional distillation, and rotary evaporators.

• Organic Chemical Synthesis: Perfectly suited for complex organic synthesis, refluxing setups, and prolonged boiling reactions.

• High-Vacuum Operations: The spherical geometry provides maximum structural resistance against implosion, making it highly safe for reduced-pressure distillation and vacuum applications.

• Uniform Heating & Boiling: Prevents localized “hot spots,” ensuring smooth, uniform boiling and minimizing the risk of thermal cracking.

Product Features:

• Industrial-Strength Borosilicate Glass: Boasts an exceptionally low coefficient of thermal expansion, providing maximum protection against extreme thermal shock.

• Precision Ground Glass Joint: Available with standard taper ground joints (e.g., 24/40 or 14/20) to guarantee airtight, leak-free connections with condensers, adapters, and addition funnels.

• Optical Clarity & Inertness: Completely resistant to chemical corrosion from aggressive acids, bases, and organic solvents, allowing for unobstructed visual monitoring of the reaction mass.

⚠️ Safety and Handling: Always inspect the flask for hairline cracks, scratches, or star-fractures before applying heat or pulling a vacuum; compromised glassware can fail or implode under stress. Use a heating mantle, oil bath, or sand bath to heat round-bottom flasks—never place them directly on a flat hot plate surface. Always wear appropriate Personal Protective Equipment (PPE), including splash-proof safety goggles and a face shield when working under vacuum.
