Distilling flasks supplied by LabChoice Australia are designed for efficient vapor generation and controlled separation during distillation, reflux and solvent purification workflows in analytical, teaching and industrial laboratories. Manufactured from premium BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these flasks deliver excellent thermal stability, chemical resistance and mechanical durability under repeated heating and cooling cycles. The spherical body promotes uniform heat distribution, reducing localised stress and supporting smooth boiling behaviour.

Each distilling flask features a precision formed neck with an integrated side arm that directs vapors toward the condenser while minimising liquid carryover. Ground glass joints are produced in accordance with ISO 383 and ASTM E676 specifications, ensuring leak tight compatibility with condensers, adapters, splash heads and receivers. The uniform wall thickness and high clarity BORO 3.3 construction allow clear observation of boiling, vapor formation and distillation progress, supporting safe and controlled operation under atmospheric or reduced pressure conditions.

Distilling flasks are widely used in organic synthesis, solvent recovery, essential oil distillation, petrochemical analysis, pharmaceutical research, ammonia analysis and academic laboratories. They are suitable for simple and fractional distillation, reflux setups and preparative workflows where reliable vapor transfer and temperature control are essential. The side arm configuration improves separation efficiency and integrates seamlessly into modular distillation assemblies.

All distilling 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 dependable distillation vessels.
