The flat-bottom spherical flask with a standard ground glass joint is a laboratory vessel designed for processes of heating, distillation, and mixing of substances under controlled conditions, offering an optimal combination of thermal stability and functionality. Its spherical geometry favors a homogeneous heat distribution, which allows for uniform boiling and improves efficiency in operations requiring precise thermal control.
Manufactured from borosilicate glass 3.3 in accordance with DIN 12347, ISO 4797, and USP standards, it presents excellent chemical resistance against common acids, saline solutions, bases, and organic compounds, maintaining its stability even under demanding conditions. Its low coefficient of thermal expansion gives it high resistance to thermal shock, allowing work at temperatures up to approximately 500 °C without compromising the integrity of the vessel.
The flat base provides stability on work surfaces or heating equipment, facilitating its handling without the need for additional supports in certain applications. The standard ground glass joint allows precise coupling with other glass elements, such as condensers, stoppers, or adapters, ensuring a tight seal and effective integration in experimental setups.
Its transparency facilitates direct observation of processes, allowing continuous visual control during work. Available in different capacities, this flask adapts to multiple laboratory needs, both in research environments and teaching applications, offering a reliable, durable, and versatile solution for procedures requiring precision and safety.
