Erlenmeyer (conical) flasks are versatile glass vessels for mixing, heating, culturing, and temporary storage. The conical shape reduces splashing during swirling and supports use with stoppers or caps. Options include narrow or wide necks, clear graduations, reinforced rims, and standard ground-glass joints for secure connections. Borosilicate glass provides chemical resistance and thermal durability for hotplate or autoclave use. Available in a wide range of capacities for routine laboratory procedures.
