The United Scientific Flat Bottom Boiling Flasks are essential components for any laboratory focused on organic synthesis, distillation, or general reagent preparation. These flasks combine the thermal advantages of a rounded body with the convenience of a flat base, allowing them to stand independently on lab benches, hot plates, and heating mantles without the need for support rings or cork stands. Constructed from low-expansion Type I borosilicate glass, these flasks are engineered with uniform wall thickness. This precision manufacturing ensures superior mechanical strength and exceptional resistance to thermal shock, making them reliable for rigorous heating and boiling applications.

Lead Times May Vary.

From micro-scale reactions to bulk processing, we offer a wide range of capacities in both convenient multi-packs and individual large-format units.

Key Functional Benefits:

Self-Standing Stability: The flat base allows for safe placement on analytical balances and benchtop surfaces, reducing the risk of spills during sample prep
Uniform Heat Distribution: The spherical body promotes even heating of contents, while the flat bottom ensures maximum surface contact with hot plates
Reinforced Rims: Each flask features a heavy-duty tooled rim to prevent chipping and to provide a secure fit for rubber stoppers or corks
Chemical Durability: Highly resistant to water, neutral and acid solutions, concentrated acids, and organic substances

Laboratory Safety & Care Insights:

Heating Uniformity: When using a flat bottom flask on a hot plate, ensure the plate surface is clean and level. To avoid "bumping" during boiling, always add boiling chips or a magnetic stir bar before heating begins
Pressure Warning: Flat bottom flasks are designed for heating and boiling at atmospheric pressure. They should not be used for vacuum applications or high-pressure reactions; for those tasks, a round bottom flask is required to distribute stress evenly
Thermal Gradient: Avoid placing a hot flask directly onto a cold stone or metal benchtop. Use a heat-resistant pad or cork ring to allow the glass to cool gradually
