Description
Round bottom boiling flask is ideal for precise thermal applications such as distillation, reflux, and synthesis. Its curved base promotes even heat transfer, essential for consistent chemical reactions and controlled boiling processes.
Used widely in organic chemistry, pharmaceutical development, and teaching laboratories, it must be supported by a ring stand or heating mantle during use due to its spherical shape.
Manufactured from LabChoice BORO 3.3 borosilicate glass, the flask delivers excellent chemical durability and thermal resistance. Supplied by LabChoice Australia, it ensures reliable performance in high-temperature and corrosive lab conditions.
