Pear Shaped Flask For Distillation, BORO 3.3 Glass
didn't see what you are looking for ?
Pear shaped flasks supplied by LabChoice Australia are designed for efficient heating, evaporation and distillation where controlled liquid concentration and smooth boiling behaviour are required. Manufactured from premium BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these flasks offer excellent thermal stability, chemical resistance and mechanical durability under repeated heating and cooling cycles. The pear shaped profile concentrates liquids toward the base, improving heat transfer efficiency and reducing solvent retention compared with round bottom designs.
Each pear shaped flask features a precision ground glass neck produced in accordance with ISO 383 and ASTM E676 specifications, ensuring leak tight compatibility with condensers, vacuum adapters, short path heads and rotary evaporator assemblies. The tapered lower section promotes smooth boiling and minimises bumping, while the uniform wall thickness supports safe use under atmospheric or reduced pressure conditions. High clarity BORO 3.3 glass allows clear observation of boiling behaviour, phase changes and solvent recovery throughout the process.
Pear shaped flasks are widely used in rotary evaporation, vacuum distillation, solvent concentration, extract drying, pharmaceutical research, botanical extraction and analytical sample preparation. Their geometry is particularly suitable for low to medium volume samples where efficient evaporation and minimal sample loss are critical. They integrate easily into modular glassware systems used in both teaching laboratories and advanced research environments.
All pear shaped flasks supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional accuracy verification, joint taper conformity assessment, wall thickness measurement, thermal shock testing and surface clarity inspection. Each flask is validated for full compliance with ISO 3585 and ASTM E438 borosilicate performance standards, and all jointed interfaces meet ISO 383 and ASTM E676 interchangeability requirements. These rigorous quality measures ensure safe, reliable and long lasting performance for laboratories requiring high quality evaporation and distillation vessels.
