Expansion Adapter Borosilicate BORO 3.3 Glass
didn't see what you are looking for ?
Expansion adapters supplied by LabChoice Australia provide essential pressure relief, vapor expansion capacity and system volume adjustment for distillation, reflux and reduced pressure workflows in analytical, industrial and research laboratories. Manufactured from premium BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these adapters offer excellent thermal stability, chemical resistance and mechanical strength during heating, cooling and vacuum cycling. Their widened chamber design helps prevent bumping, foaming carryover and thermal shock in reaction vessels by allowing vapors to expand safely before entering downstream components.
Each expansion adapter features precision ground joints produced in accordance with ISO 383 and ASTM E676 specifications, ensuring secure, leak tight compatibility with boiling flasks, condensers, stillheads, fractionation columns and vacuum assemblies. The smooth internal bore promotes uninterrupted vapor flow while reducing the risk of sample loss or contamination. High clarity BORO 3.3 construction supports clear visibility of vapor behaviour, condensate formation and reaction dynamics during operation.
Expansion adapters are widely used in organic synthesis, vacuum distillation, terpene refinement, essential oil processing, cannabinoid research, polymer chemistry, educational laboratories and general chemical workflows. Their ability to buffer pressure fluctuations improves process safety, reduces risk of glassware failure and enhances control over reactions prone to sudden boiling or foaming. They also help protect delicate downstream components such as condensers and receivers by moderating vapor velocity and volume.
All expansion adapters supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional verification, joint taper conformity assessment, clarity evaluation, stress point testing and thermal shock resistance checks. Each unit is validated for compliance with ISO and ASTM borosilicate performance requirements, and all joints meet Iinterchangeability standards. These rigorous quality measures ensure dependable, safe and long lasting performance for laboratories requiring controlled expansion capacity within distillation and reaction systems.
