PYREX 50mL Narrow Mouth Erlenmeyer Flask with PYREX Standard Taper Stopper-CGW 5020-50

These narrow mouth PYREX® Erlenmeyer flasks have PYREX® ST stoppers. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks are graduated to show approximate capacity. The 25, 50 and 125mL flasks are satisfactory for use as weighing bottles. For replacement stoppers see Corning No. 7650.
