Crimp seals ND11 are made of aluminium. They are clear or lacquered in different colours and have a 5.5 mm hole. They are supplied with fitted septa made of a variety of materials. Thickness: 0.06 mm. Package of 100 pieces.
Septa made of aluminium are free of halogens and elastomers and suitable for storing standards or reactive substances that can attack normal septum materials. There is also no risk of contamination of the samples with plasticizers, silicone or butyl rubbers or PTFE, FEP or TEF components. A ring placed above the aluminium septum achieves an excellent seal on the stopper system.
