10 mm Wide Mouth screw caps with septum
ms-Pure septum: non-pigmented silicone septum
The ms-Pure silicone/PTFE septum is produced from natural non-pigmented silicone/ PTFE. Tests show that it is 60 % purer than „standard“ silicone/PTFE septa from other producers. With an increasing sensitivity of analytical instruments, there is an increasing demand for extra pure septum material to prevent a contamination of the sample with extractable substances from the septum.
