300ml Amber Glass Boston Bottle & Urea Polycone Cap
This 300 ml amber glass Boston bottle with urea polycone cap is designed for higher value or more demanding formulations that benefit from a firm seal. Often chosend for concentrates, actives and specialist liquids where closure performance is a key requirement.
The amber Boston round bottle provides robust containment and reduced light transmission for suitable sensitive contents. The urea cap has a rigid body and polycone insert that compresses securely into the 28 mm neck, supporting an especially close seal on compatible products. This combination is useful when bottles are shipped, stored for longer periods or used with aggressive blends that may challenge lighter closures. A 300 ml volume works well for stock solutions, fragrance bases and speciality products in laboratories, studios and manufacturing environments. Straight sides allow for detailed composition, hazard and handling labelling.
