Jacketed Round Bottom Double Wall Flask For Distillation BORO 3.3

Description Description A jacketed round bottom flask is a specialised double wall distillation vessel designed for controlled heating and cooling during chemical separation, solvent purification and process development. The outer jacket allows circulation of thermostatic fluids that stabilise temperature across the flask body, preventing uneven heat distribution that can alter boiling behaviour or affect fraction quality. LabChoice Australia supplies these flasks in BORO 3.3 glass that meets ISO 3585 and ASTM E438 Type 1 Class A, ensuring thermal stability, chemical resistance and clarity required for advanced distillation work. The round bottom shape improves mixing efficiency and provides uniform surface exposure to heating mantles, baths or circulators. The jacket enhances this by maintaining consistent heat transfer during sensitive operations such as essential oil recovery, solvent recycling, vacuum distillation and fraction collection. Researchers and technicians working in organic chemistry, environmental analysis and pharmaceutical prep labs use these vessels when precise thermal control directly influences purity and yield. The smooth inner geometry and high quality joints allow secure integration with condensers, adapters and fractionating columns used across Australian universities and R and D laboratories. BORO 3.3 construction supports repeated thermal cycling in demanding workflows including reduced pressure distillation, azeotropic separations and temperature programmed reflux. The high clarity glass allows direct monitoring of boiling behaviour, bumping, head temperature response and phase changes during both atmospheric and vacuum processes. LabChoice Australia provides consistent quality to support predictable distillation outcomes where accuracy, reproducibility and safety are essential for teaching, method development and small scale production environments.
