Description
A four neck round bottom boiling flask offers a highly adaptable platform for complex reaction assemblies, allowing simultaneous attachment of condensers, thermometers, gas inlets, mechanical stirrers, and addition funnels. Manufactured from premium LabChoice BORO 3.3 glass, the flask provides excellent thermal stability, low expansion, and robust chemical resistance, meeting the performance expectations of ISO 3585 and ASTM E438 Type I laboratory glassware standards.
The uniform round bottom ensures consistent heat distribution for reliable boiling, reflux, and distillation during organic synthesis, analytical chemistry, and multi step reaction development. Each precision ground joint provides a tight, leak free seal that maintains vacuum integrity for sensitive or inert atmosphere processes. The reinforced wall thickness and high temperature durability support heating mantle use, cooling cycles, and repeated exposure to aggressive cleaning solvents without structural compromise.
Supplied by LabChoice Australia, this four neck jointed boiling flask is engineered for research laboratories, universities, and industrial R&D teams conducting advanced chemical workflows. Its multi neck configuration enhances control over reagent addition, temperature monitoring, and gas management, making it an essential vessel for demanding reaction setups across Australian scientific and industrial environments.
