Description
Extension Adapter is designed to increase the effective length between two ground glass joints in a laboratory assembly, creating safer spacing, improved clearance, and better alignment of connected components. It is commonly used in distillation and reflux setups to separate heat sources from sensitive joints, create room for clamps and supports, and prevent condensers, receiving adapters, or accessory glassware from sitting too close to the flask or heating mantle. This simple change can reduce mechanical stress on joints and improve overall apparatus stability during extended runs.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the extension adapter offers excellent thermal stability, low thermal expansion, and strong chemical resistance for routine contact with common laboratory solvents and reagents. BORO 3.3 performance is consistent with recognised borosilicate glass standards such as ISO 3585 and ASTM E438 Type I, supporting reliable service under heating and cooling cycles and daily laboratory handling. Precision ground glass joints help deliver a secure, low leak connection when properly assembled, which is particularly important in vacuum distillation, inert gas work, and solvent recovery where sealing integrity directly affects results.
Supplied by LabChoice Australia, this extension adapter is widely used across Australian university laboratories, teaching facilities, research institutes, and industrial quality control environments where modular glassware flexibility and safer apparatus geometry are priorities. It is an essential accessory for building professional glassware configurations while protecting joints, improving clearance, and maintaining consistent workflow performance.
