Extension Adapter Borosilicate Glass Laboratory Grade
didn't see what you are looking for ?
Extension adapters supplied by LabChoice Australia are designed to provide additional length, clearance and positional flexibility within jointed glassware assemblies used for distillation, reflux, extraction and general synthetic chemistry. Manufactured from high quality BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these adapters offer excellent thermal resistance, chemical durability and dimensional precision. Their robust construction ensures stable performance during repeated heating and cooling cycles encountered in demanding laboratory workflows.
These adapters are used to raise the height of condensers, stillheads, thermometers or other apparatus components, allowing technicians to optimise alignment, accommodate heating mantles, prevent contact with support stands or improve safety clearances. The precision ground joints provide a leak resistant seal with standard cone and socket glassware, ensuring reliable vapour flow and maintaining internal pressure stability during operation. The high clarity BORO 3.3 glass allows full visual inspection of the connection points throughout assembly and use.
Extension adapters are widely used in organic chemistry, essential oil distillation, academic teaching laboratories and research settings where apparatus height or spacing must be adjusted without altering the core glassware configuration. Their chemical resistance allows compatibility with acids, solvents and reagents used in advanced synthesis, analytical preparation and quality control environments.
Each extension adapter supplied by LabChoice Australia undergoes ISO 9001 aligned quality control inspections. This includes dimensional verification of joint tapers, clarity and surface finish assessment, wall thickness measurement and evaluation of structural integrity. Adapters are examined for joint precision, smooth glass transitions and stable fit before packing. These quality measures ensure reliable performance for laboratories requiring adaptable, high quality spacing components for glassware assemblies.
