Description
Boiling Flask, Flat Bottom, Borosilicate Glass (BORO 3.3) is designed for safe heating, boiling, and reaction work where thermal stability, chemical resistance, and reliable bench handling are essential. The flat bottom allows the flask to stand upright without a cork ring, supporting easier filling, weighing, mixing, and short term storage. It is widely used for heating and boiling solutions, reagent preparation, solvent evaporation steps, and general laboratory procedures across teaching, research, and industrial QC environments.
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 chemicals 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 flat base provides stable placement on hotplates and bench surfaces, while the rounded body encourages efficient swirling and mixing. For best practice, use gradual heating, avoid direct flame contact unless your method allows and the flask is correctly supported, and reduce thermal shock risk by avoiding sudden temperature changes. Proper clamping and use of appropriate stands further improves safety when heating or mixing larger volumes.
Supplied by LabChoice Australia, this BORO 3.3 flat bottom boiling flask is a dependable choice for Australian schools, universities, research institutes, and industrial laboratories requiring durable, chemically resistant glassware for everyday heating and preparation work.
