Corning Pyrex 250 ml Narrow Mouth Erlenmeyer Flask With Baffles

These 250 mL PYREX Erlenmeyer flasks have heavy tooled rims for maximum durability. The same baffle design as found on PYREX Delong flasks promotes optimal and consistent solution agitation when used with flask shakers. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks include a marking spot.
