Snap ring seals ND11 are made of PE and are supplied with fitted septa made of a variety of materials. They have a 6 mm centre hole.
By dispensing with the PTFE layer on the septa, these screw seals are ideal for PFAS analysis.
The snap ring seals do not have a septum, but are made entirely of PE. The special, thinned penetration point enables simple and safe sampling. The absence of a septum makes these closures ideal for PFAS analysis.
