Description
A three neck round bottom flask provides the flexibility required for complex laboratory reactions where multiple connections must operate simultaneously. Manufactured from high quality LabChoice BORO 3.3 glass, the flask offers excellent thermal stability, low thermal expansion, and strong chemical resistance in accordance with ISO 3585 and ASTM E438 Type I laboratory glassware standards.
The round bottom design ensures uniform heat distribution during boiling, reflux, and distillation, supporting consistent reaction control in organic synthesis, analytical chemistry, and research scale processing. The three precision ground joints allow secure attachment of condensers, thermometers, dropping funnels, gas inlets, or stirring systems, enabling accurate reagent addition and temperature monitoring while maintaining vacuum integrity. Consistent wall thickness enhances durability through repeated heating and cooling cycles.
Supplied by LabChoice Australia, this three neck jointed round bottom flask is widely used in universities, research laboratories, and industrial R&D facilities across Australia. Its robust construction and versatile configuration make it a dependable vessel for advanced reaction setups requiring precision, reproducibility, and long term laboratory performance.
