Product Description
These round bottom boiling flasks are essential for laboratory heating, distillation, evaporation, and synthesis. Manufactured from premium borosilicate glass, they offer excellent chemical and thermal resistance, even under repeated heating and cooling cycles. Their spherical design ensures even heat distribution and reduces stress during vigorous boiling.
Available in a wide range of capacities (25 mL to 20000 mL), these flasks are suitable for both small-scale analytical experiments and large-scale reactions or solvent recovery in industrial labs. The flasks are fully compliant with IS 1381-1 and ISO 1773 standards, ensuring reliability and compatibility with common laboratory equipment.
