Product Details
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.
