This 500mL polystyrene disposable sterile media storage bottle has been designed specifically to store common laboratory solutions such as tissue culture media, serum and buffers. This bottle is optically clear, has low extractable substances and good alcohol compatibility. It is radiation sterilized and is an ideal choice for storage of liquids used in tissue culture. Each AutoFil™ sterile lab storage bottle has features that improve the handling of the bottle especially when the bottle is wet. The bottle itself has a slopped-side design that improves stability when placed on the work surface. The narrow bottle shoulder combined with molded finger grips improves the ability to securely grip the bottle with gloved hands. Lastly, the patented* bottle cap enables easy handling and carrying of the bottle. This innovative cap also allows for easy uncapping, tightening and bottle stacking and provides a large surface for bottle labeling. This media storage bottle works ideally with the Whatman Klari-flex™ media filtration system to provide vacuum filtration of aqueous solutions such as cell culture media, biological fluids, and buffers.
