Cone adapters supplied by LabChoice Australia provide reliable, leak resistant transitions between different joint sizes and configurations in laboratory glassware assemblies. Manufactured from high quality BORO 3.3 borosilicate glass that meets ISO 3585 and ASTM E438 Type 1 Class A standards, these adapters offer excellent thermal stability, chemical resistance and dimensional accuracy. Their strong mechanical integrity allows seamless use in distillation, reflux, extraction and general synthetic chemistry workflows involving repeated heating and cooling cycles.
Cone adapters are designed with a precision ground taper that ensures a secure fit with standard jointed glassware. By allowing technicians to connect mismatched joint sizes or convert between cone and socket joints, these adapters provide essential flexibility in building and modifying laboratory setups. This enables efficient integration of condensers, flasks, stillheads, receivers and specialised components without requiring duplicate glassware in multiple joint sizes. The clear BORO 3.3 glass construction also provides full visibility of the connection points, supporting safe and accurate assembly.
These adapters are widely used in organic chemistry, analytical laboratories, teaching facilities, essential oil distillation and industrial research environments. Their ability to maintain airtight connections helps preserve internal pressure and prevent vapour loss during sensitive operations such as fractional distillation, reflux heating, solvent purification and temperature controlled reactions. Their chemical durability allows compatibility with acids, bases, organic solvents and reactive reagents commonly found in advanced laboratory workflows.
Every cone adapter supplied by LabChoice Australia undergoes ISO 9001 aligned quality control inspection. This includes dimensional verification of joint tapers, assessment of clarity and surface finish, wall thickness measurement and testing for secure sealing performance. Each unit is examined for structural strength and uniformity before packing. These rigorous checks ensure dependable performance for laboratories requiring precise and adaptable joint conversion solutions.
