Erlenmeyer Jointed Conical Flask without Graduation is a BORO 3.3 borosilicate glass flask designed for mixing, heating, reaction work, and modular glassware assemblies where secure ground joint connections are required. The conical Erlenmeyer shape supports efficient swirling with reduced splash risk, while the jointed neck allows connection with compatible condensers, adapters, dropping funnels, gas inlets, and vacuum connections for reflux, controlled additions, and sealed assembly workflows.

Manufactured from high quality BORO 3.3 borosilicate glass, this flask provides excellent thermal stability, low thermal expansion, chemical resistance, and clear visibility for routine laboratory use. BORO 3.3 glass is suitable for repeated heating and cooling cycles when handled correctly, making it a dependable option for chemistry teaching, research, synthesis, and quality control applications. Smooth internal surfaces help minimise residue retention and support efficient cleaning between runs, while consistent wall thickness improves robustness for daily bench handling.

The without graduation format provides a clean, uncluttered body for reaction work and general mixing where volumetric measurement markings are not required. This improves visual observation of turbidity, precipitation, colour change, and phase behaviour during experiments. The wide base improves stability on benchtops and compatible heating equipment, while the precision ground joint supports secure, low-leak connections when correctly assembled and clamped.

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 borosilicate glass categories. 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 without Graduation provides a practical BORO 3.3 glassware option for schools, universities, research laboratories, reflux setups, controlled additions, closed-system procedures, and industrial quality control environments requiring durable, chemically resistant glassware with reliable joint compatibility.
