Premium Round Bottom Flask 250ml Flat Bottom Boiling Flask – Borosilicate Glass

Engineered for precision and safety, this 250ml Flat Bottom Boiling Flask is a staple for any professional, educational, or industrial laboratory. Combining the thermal efficiency of a round body with the convenient stability of a flat base, it is designed to withstand extreme temperature fluctuations and rigorous chemical exposure.

Crafted from Grade 3.3 Borosilicate glass, this flask offers industry-leading resistance to thermal shock, ensuring it remains durable during intense heating and cooling cycles. Whether you are performing distillations, chemical reactions, or simple liquid storage, this flask provides the reliability required for high-accuracy results.

Key Features

• Superior Thermal Resistance: Made from low-expansion 3.3 Borosilicate glass, capable of withstanding high temperatures and thermal gradients.

• Self-Standing Design: The integrated flat base allows the flask to stand upright on benches and hot plates without needing a support ring.

• Uniform Wall Thickness: Precision-blown walls ensure even heat distribution, reducing the risk of “hot spots” and breakage.

• Chemical Inertness: Highly resistant to water, neutral and acid solutions, strong acids, and organic substances.

• Reinforced Rim: Features a heavy-duty beaded rim for increased mechanical strength and secure stopper fitment.
