Description
Buchi Rotavapor Evaporating Flask, BORO 3.3 is designed for rotary evaporation where reliable vacuum performance, rapid solvent removal, and thermal shock resistance are essential. Used on Büchi style rotavapor systems, the evaporating flask rotates in a heated bath to create a thin film of solvent, increasing surface area for faster evaporation while supporting controlled distillation under reduced pressure. It is widely used for solvent recovery, concentration of extracts, fraction pooling, and sample preparation in research laboratories, universities, natural product work, and industrial quality control.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the flask offers excellent thermal stability, low thermal expansion, and strong chemical resistance to a wide range of common laboratory solvents and reagents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under repeated heating and cooling cycles and the pressure differentials associated with vacuum evaporation. Smooth internal surfaces help minimise residue retention for efficient cleaning, and consistent wall thickness supports safer operation during rotation and vacuum use.
Designed for secure connection to rotary evaporator vapour ducts via the appropriate joint fitting, this evaporating flask supports low leak integration when correctly assembled and clamped. For best practice, avoid overfilling, balance loads where applicable, inspect for chips or star cracks before vacuum use, and use gradual temperature changes to reduce thermal shock risk.
Supplied by LabChoice Australia, this BORO 3.3 Büchi rotavapor evaporating flask is widely used across Australian universities, research institutes, environmental labs, and industrial QC facilities where robust borosilicate performance and reliable rotary evaporation outcomes are required.
