Amber Colour Hollow Glass Stoppers are designed for sealing laboratory glassware containing light-sensitive chemicals or solutions. The amber glass reduces light transmission, helping to protect contents from degradation. The hollow construction minimizes weight while maintaining strength and durability. Made from high-quality borosilicate glass, these stoppers provide excellent thermal and chemical resistance with a precision-ground surface for a secure, leak-resistant fit in laboratory applications.
