Designed for PP28 screw-neck bottles, these aluminium caps allow liquid extraction or injection via hypodermic needle without opening the container, ensuring a hermetic seal and preserving sample integrity at all times.
The butyl septum, thanks to its self-sealing properties after puncture, provides a practical and safe solution for working with air-sensitive samples, volatile solvents, or any substance requiring controlled and repeatable access without compromising the internal conditions of the bottle.
Its design without a tamper-evident seal allows for quick handling in the laboratory, while the robustness of the aluminium ensures a firm and long-lasting closure. The cap-septum assembly is compatible with standard PP28 screw-neck bottles, making it a versatile and easy-to-integrate option for any working environment.
