Conical Erlenmeyer Flask

Disclaimer: Flasks may not be perfectly flat on the bottom and may have minor surface imperfections.

Bring efficiency and convenience to any experiment with the Glass Conical Flask. These conical flasks perform a wide variety of functions and are commonly used in laboratory settings. Conical flasks can capture, store, and measure material when used with a Buchner funnel or glass funnel. But that’s not all. This flask can also mix, boil, and heat chemicals, thanks to its uniform, thick walls, unique design, and stopper for heating. Our conical flasks are flat bottomed and come with ground 24/40 joint, and if used in a vacuum application, requires vacuum grease to help create an airtight vacuum seal during the process. Additionally, the Glass Conical Flasks are thermal shock resistant and chemical resistant. Its tapered sides and narrow neck allows for easy swirling and stirring of an experiment.
