Corning square polycarbonate storage bottle is easier to handle, require less space (13-20%) on the shelf or in the autoclave, and is ideal for mixing, sampling, and storage. Strong polycarbonate bottle is more break resistant than other glass or plastic bottles. Comes with a linerless, 45mm one-piece autoclavable orange GL45 threaded polypropylene plug seal cap. Features screened white enamel graduations that are easier to see than molded graduations, and a large white marking spot for easier identification. Sterilized by gamma radiation. Bottle can be autoclaved once at 121°C and 15psi. Repeated autoclaving weakens polycarbonate and is not recommended. Optional reusable cap with silicone septa for syringe sampling or introduction of reagents is available. Graduated. Disposable. Sterile
