Erlenmeyer conical flasks supplied by LabChoice Australia provide a versatile, stable and chemically inert vessel for mixing, culturing, heating and solution preparation across teaching, analytical and industrial laboratory environments. Manufactured from high clarity BORO 3.3 borosilicate glass that complies with ISO 3585 and ASTM E438 Type 1 Class A standards, these flasks deliver excellent thermal shock resistance, chemical durability and long term structural reliability. Their wide base and tapered neck design enhance stability, reduce spill risk and support controlled swirling during reagent preparation or mixing procedures.

Each Erlenmeyer flask features clear, permanent graduation markings for approximate volume measurement, thick uniform walls for repeated heating and cooling cycles and a precisely formed neck compatible with cotton plugs, rubber stoppers or ground glass joints depending on the model. The inert BORO 3.3 composition prevents interaction with acids, alkalis, solvents and biological media, ensuring consistent, contamination free performance. Their geometry supports efficient heat transfer on hot plates, water baths and other laboratory heating equipment.

Erlenmeyer conical flasks are widely used in titration setups, microbial culture preparation, buffer formulation, dissolved oxygen studies, crystallisation, sample storage and general solution handling. Their design allows easy manual mixing and vortexing, making them ideal for education laboratories, industrial R and D, environmental analysis and food and beverage chemistry. The broad base offers stable benchtop placement while the narrow neck helps minimise evaporation and splashing during mixing.

All Erlenmeyer flasks supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional verification, graduation accuracy assessment, wall thickness measurement, thermal shock testing and clarity evaluation. Each flask is further validated for full compliance with ISO 3585 and ASTM E438 borosilicate glass performance requirements. These rigorous quality processes ensure dependable, safe and long lasting operation for laboratories requiring precision engineered conical glassware.
