Premium borosilicate 3.3 construction – Manufactured from high-quality borosilicate 3.3 glass, offering exceptional thermal resistance, chemical durability, and mechanical strength, making the tube suitable for demanding laboratory workflows and repeated heating–cooling cycles.
Amber-tinted protection for light-sensitive samples – The amber-colored glass effectively shields contents from UV and visible light, preventing photodegradation and ensuring long-term sample integrity during storage, handling, or experimental procedures.
Precision-ground interchangeable stopper/socket – Equipped with a perfectly ground stopper/socket that provides a secure, airtight seal to prevent contamination, evaporation, and accidental spillage, while ensuring compatibility with a wide range of jointed-glass laboratory apparatus.
