Erlenmeyer Jointed Conical Flask is a BORO 3.3 borosilicate glass flask designed for mixing, heating, reaction work, and modular glassware assemblies where a secure ground joint connection is required. The conical Erlenmeyer shape supports controlled swirling and efficient mixing while helping reduce spillage compared with straight-sided vessels. The jointed neck allows connection with compatible condensers, adapters, dropping funnels, and inert gas fittings for reflux, controlled additions, filtration assemblies, and closed or semi-closed laboratory setups.
Manufactured from high quality BORO 3.3 borosilicate glass, this flask provides strong chemical resistance, thermal stability, low thermal expansion, and clear visibility for monitoring solutions during laboratory work. BORO 3.3 glass is widely used for laboratory glassware because it supports repeated heating and cooling cycles when handled correctly. Smooth internal surfaces help reduce residue retention and support easier cleaning between runs, while the stable base supports practical use on laboratory benches and compatible heating equipment.
The precision ground joint supports secure, low-leak connections when correctly assembled, clamped, and used with compatible jointed glassware. This helps reduce solvent loss and supports more reproducible workflows during reflux, controlled mixing, or reaction procedures. For best practice, jointed assemblies should be properly supported with clamps, heated gradually, and protected from sudden temperature changes to reduce the risk of thermal shock.
For material and quality reference, ISO 3585 specifies the properties of borosilicate glass 3.3 used for laboratory glassware, glass plant, pipeline, and fittings. ASTM E438 covers glasses used in laboratory apparatus, including Type I low-expansion borosilicate glass. ISO 9001 may also be used as a general quality management reference where supplier or manufacturer certification is available. These references should only be used as compliance claims where supported by manufacturer documentation and product certification.
For LabChoice Australia customers, Erlenmeyer Jointed Conical Flask provides a practical BORO 3.3 glassware option for schools, universities, research laboratories, chemistry teaching, synthesis work, reflux setups, controlled additions, and industrial quality control environments requiring reliable joint compatibility and durable laboratory glassware.
