Round bottom flask

Round Bottom Flask - Professional Laboratory Glassware

Round bottom flasks are essential laboratory glassware designed for heating, mixing, and chemical reactions in professional laboratory environments. These spherical laboratory vessels provide optimal heat distribution and are indispensable for synthetic chemistry, distillation processes, and reflux operations across research facilities, educational institutions, and industrial laboratories.

Key Features

• Superior heat distribution through spherical design minimizing hot spots
• Ground glass joints for secure connections with laboratory equipment
• High-quality borosilicate glass construction for chemical resistance
• Multiple neck configurations available for versatile experimental setups
• Graduated and non-graduated options for precise volume measurements
• Temperature resistance from -70°C to +500°C for diverse applications

Applications

Round bottom flasks are crucial for organic synthesis, solvent evaporation, vacuum distillation, and reflux reactions. They excel in pharmaceutical research, chemical analysis, educational demonstrations, and quality control testing. The spherical geometry makes them ideal for reactions requiring uniform heating and efficient stirring.

Technical Specifications

Available in capacities from 5mL to 20L with standard taper joints (14/20, 19/22, 24/29, 29/32). Manufactured from Type I borosilicate glass with low thermal expansion coefficient (3.3 x 10⁻⁶/K). Compatible with heating mantles, oil baths, and magnetic stirrers for comprehensive laboratory workflows.
