250ml Amber Glass Boston Bottle & Urea Polycone Cap
This 250 ml amber glass Boston bottle with urea polycone cap is tailored for more demanding formulations that benefit from both amber protection and a particularly firm seal. This combination is often chosen for high-value liquids that require an upgraded closure.
The Boston round amber bottle offers good impact resistance and reduced light transmission, making it suitable for selected chemicals, essential oil blends and concentrated actives. The urea cap incorporates a rigid body and polycone insert that compresses securely into the 28 mm neck, supporting a tighter seal than many standard caps, subject to compatibility testing. A 250 ml capacity suits stock solutions, fragrance bases and speciality products used regularly in labs, studios or manufacturing. The straight body gives you plenty of space for detailed safety and composition labelling.
