Product Review

New Pyrex slim line media storage bottles provide easier handling and more efficient storage of media, biologicals, and other aqueous solutions. Slim line media bottles feature indented gripping zones along the sides of the bottle to allow easier and safer handling, and a new cap design that permits faster opening and closing. The caps are fully compatible with all standard "GL45" (45mm neck size) Pyrex bottles. Widely-spaced knurls (ridges and grooves) provide comfortable and ergonomic cap handling, and the narrow bottle diameter allows more efficient storage on shelves, refrigerators, or autoclaves. Bottles are graduated to their full working volumes. Pyrex slim line bottles are made from the same Type 1 Class a (ASTM e-438) borosilicate glass as standard Pyrex media bottles for chemical and heat resistance.
