Corning® Sterile Roller Bottles are seamless and optically-clear. Made with polystyrene, the bottles come pre-sterilized with gamma radiation. They are certified non-pyrogenic to a documented endotoxin level of 0.5 EU/mL.
The bottles come with quick-sealing polypropylene screw caps. Smooth edges and large knurls (EF24927) ensure easy opening. Replacement caps for 850cm2 easy grip (EF24927) can be ordered below.
A ribbed internal growth surface provides twice the growth surface of the smooth interior bottle. Two windows allow for microscopic viewing. These can also be used as pouring surfaces.
