Description
Boiling Flask Flat Bottom, Socket Joint, Short Neck, Borosilicate Glass (BORO 3.3) is designed for safe heating, boiling, and reaction work where thermal stability, chemical resistance, and secure ground joint connections are essential. The flat bottom allows the flask to stand upright on the bench without a cork ring, supporting easier filling, weighing, and temporary storage. A short neck provides a compact profile that improves clearance in fume cupboards and heating setups, while the socket (female) ground joint enables reliable integration with condensers, adapters, and reflux assemblies for distillation, synthesis, and solvent recovery workflows.
Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the flask offers excellent thermal stability, low thermal expansion, and strong resistance to a wide range of laboratory reagents and solvents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under repeated heating and cooling cycles and daily laboratory handling. Smooth internal surfaces minimise residue retention and support efficient cleaning between runs, while consistent wall thickness improves robustness for routine heating applications.
The precision ground socket joint supports a secure, low leak connection when properly assembled and clamped, helping maintain stable reflux and reduce solvent loss. This makes the flask suitable for heating and boiling steps in organic chemistry, sample digestion, reagent preparation, and general laboratory procedures requiring controlled connection to condensers or addition funnels. For best practice, use appropriate heating methods, avoid sudden temperature changes, and support glassware with stands and clamps to reduce joint stress.
Supplied by LabChoice Australia, this flat bottom boiling flask is widely used across Australian schools, universities, research institutes, and industrial quality control facilities where robust BORO 3.3 construction and dependable joint compatibility are required.
