50ml Amber Glass Boston Bottle & Urea Polycone Cap
This 50 ml amber glass Boston bottle with urea polycone cap is intended for demanding formulations that need stronger closure performance in a small volume. You can use it when you want enhanced chemical resistance and a tighter seal compared with many standard palstic caps.
The amber Boston round bottle offers good stability and helps reduce light transmission for suitable light-sensitive actives, oils and reagents. The urea formaldehyde cap incorporates a polycone insert that compresses firmly into the 28 mm neck, supporting a close seal and improved resistance to many aggressive blends, subject to compatibility checks. At 50 ml, the bottle is ideal for high value, high strength contents that are dispensed sparingly. The 28 mm neck remains compatible with other closures in your 28 mm system if you expand the range. Straight sides provide space for detailed hazard and composition labelling.
Practical Applications
– Storing solvent rich actives, fragrance bases or concentrates
– Holding analytical standards and reference solutions in small volumes
– Packing aggressive or higher risk formulations where an improved seal is desirable
– Supplying specialist additives or boosters to laboratories and manufacturers
