Product Description
Combine the strength and even heating of a round bottom flask with the easy access of a flanged top. A spherical body sits well in heating mantles, while the wide ground flange lets you charge solids, insert stirrers and clean thoroughly between runs.
This listing is for Kimble catalog number 296150-0250: KONTES Spherical Reaction Flask, 250 mL. These spherical flasks have a ground flange top for use with matching multi-neck reaction flask tops and clamps, in 2 inch and 4 inch flange sizes. Capacities are 250, 300, 500, 5000 and 12000 mL.
