- Description
Description
Expansion Adapter is designed to provide a controlled transition between differing joint sizes in laboratory glassware assemblies, helping you integrate existing components without compromising alignment, sealing integrity, or apparatus stability. It is commonly used in distillation, reflux, extraction, and vacuum setups where a flask, condenser, receiving adapter, or accessory has a different joint size to the rest of the system. By creating a secure, correctly tapered connection, the adapter reduces the need for improvised coupling and supports safer, more repeatable laboratory workflows.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the expansion adapter delivers excellent thermal stability, low thermal expansion, and strong chemical resistance for routine exposure to common laboratory solvents and reagents. BORO 3.3 performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable service through heating and cooling cycles and daily bench handling. Precision ground glass joints help achieve a tight, low leak fit when correctly assembled, which is especially important in vacuum distillation, inert gas work, and solvent recovery where connection integrity directly impacts performance.
Supplied by LabChoice Australia, this expansion adapter is widely used across Australian university laboratories, research facilities, teaching environments, and industrial quality control operations for building flexible apparatus configurations while maintaining professional laboratory standards. It is an essential accessory for extending the usability of glassware inventories and improving compatibility across modular systems.
