1000ml Round Bottom Borosilicate Glass Boiling Flask
The 1000ml Simax round bottom boiling flask is designed for litre-scale heating, boiling, and solvent handling.
Borosilicate glass 3.3 provides strength against thermal shock and prolonged chemical exposure. The round bottom maintains even heat distribution during long runs, reducing hot spots in mantles and baths. A narrow neck with beaded rim enables secure stopper use and connection to condensers or vacuum adapters. Autoclavability at 121 °C supports repeat cycles in research and teaching environments.
