Product Description
These flat bottom boiling flasks are crafted for laboratory operations that require stable heating on flat surfaces such as hotplates, electric heaters, or water baths. Made from high-quality borosilicate glass, these flasks ensure excellent resistance to chemicals, acids, and temperature shock. The uniform thickness promotes safe, even heating and long-term durability during vigorous boiling or chemical reactions.
Available in both clear glass for general purpose use and amber glass for photosensitive applications, these flasks cover a wide range from 50 mL to 20000 mL. Amber flasks block UV and visible light to protect light-sensitive samples or reagents. Both variants are compliant with IS 1381-1 and ISO 1773 laboratory standards, ensuring compatibility with international laboratory protocols.
