Corning® Pyrex® Narrow Mouth Erlenmeyer Flasks with ST Stopper
By Corning
These narrow mouth Pyrex® Erlenmeyer flasks have ST stoppers for secure sealing. 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 Cat.No. 1-7650.
