Description
Flat bottom two neck flask is designed for laboratory reactions that require stability on the bench along with multiple connection points for controlled experimentation. Manufactured from high quality LabChoice BORO 3.3 borosilicate 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 flat bottom allows the flask to stand securely on hot plates or laboratory benches without additional support, while the two precision ground joints enable simultaneous attachment of condensers, thermometers, dropping funnels, or gas inlets. This configuration supports efficient reflux, controlled reagent addition, and accurate temperature monitoring during synthesis and analytical procedures. Uniform wall thickness enhances durability through repeated heating and cooling cycles, and the smooth internal surface minimises residue retention and simplifies cleaning.
Supplied by LabChoice Australia, this two neck jointed flat bottom flask is widely used in university laboratories, research institutes, teaching environments, and industrial R and D facilities across Australia. Its robust construction and practical design make it a dependable vessel for chemical synthesis, distillation, reflux operations, and educational demonstrations where stability, flexibility, and repeatable performance are essential.
