Narrow-mouth Graduated PYREX Erlenmeyer Flasks with Heavy-duty Rim
These Pyrex Erlenmeyer flasks are designed with heavy duty rims to reduce chipping. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. Approximate graduations are in durable white enamel. An extra large marking space is also provided. These non-sterile flasks are not supplied with a stopper.
