LLG-Aluminium Crimp Seals ND11, ready assembled

Crimp seals ND11 with aluminium septa
Septa made from aluminium are suitable for storing standards or reactive substances that can attack normal septum materials. There is also no risk of contamination of the samples with plasticisers, silicone or butyl rubbers or by PTFE, FEP or TEF components. A ring placed above the aluminium septum achieves an excellent seal on the stopper system.
