Description
Erlenmeyer Jointed Conical Flask, BORO 3.3 is designed for mixing, heating, and reaction work where secure ground joint connections, chemical resistance, and thermal stability are essential. The conical Erlenmeyer shape supports efficient swirling without spillage and improves mixing control compared with straight-sided vessels, while the jointed neck allows reliable integration with condensers, adapters, dropping funnels, and inert gas fittings. This makes it ideal for reflux, controlled additions, filtration assemblies, and method-based workflows that require a sealed or modular glassware setup.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the flask offers excellent thermal stability, low thermal expansion, and strong resistance to a wide range of laboratory reagents and solvents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under repeated heating and cooling cycles and daily laboratory handling. Smooth internal surfaces minimise residue retention and support efficient cleaning between runs, while consistent wall thickness improves robustness for routine bench use.
The precision ground joint supports secure, low leak connections when correctly assembled and clamped, helping reduce solvent loss and improve reproducibility during reflux or closed-system mixing. The wide base enhances stability on benchtops and hotplates, and the conical body supports controlled decanting and reduced splash during transfers. For best practice, use appropriate clamps on jointed assemblies, apply heating gradually, and avoid sudden temperature changes to reduce thermal shock risk.
Supplied by LabChoice Australia, this BORO 3.3 jointed Erlenmeyer flask is widely used across Australian schools, universities, research institutes, and industrial quality control environments where durable, chemically resistant glassware and dependable joint compatibility are required.
