Corning Pyrex Florence Boiling Flask Long Neck Flat Bottom 24/40 STJ Lot of 2 Flasks

The Corning 4080-250 is a professional-grade Pyrex Florence Flask designed for uniform heating and ease of use in laboratory distillations and boiling operations. This specific model features a flat bottom, allowing it to stand independently on lab benches or hot plates without the need for support rings. Fabricated from Pyrex borosilicate glass, these flasks offer excellent resistance to thermal shock and chemical attack, making them safe for direct heating. The long neck is finished with a heavy-duty rim to increase mechanical strength and reduce the risk of chipping. Some of the common applications for this glassware includes distillation, media preparation, and refluxing.

Used, in great condition.
