The BA 480 is a 16 fl. oz. (473 ml.) amber glass boston round bottle with a 28 mm (28-400) neck finish. The amber (brown) glass is able to filter out ultraviolet (UV) light and is primarily used for UV-sensitive products such as beer, kombucha, coffee and some pharmaceuticals. Boston rounds have a rounded shoulder and rounded base, making them popular in personal care packaging but also appropriate for applications in other industries.
