Septum N19 NK or/TEF, 45°, 1,3

Replacement septa are not offered for all cap types and sizes, as manual assembly is not recommendable due to contamination risk and possible wrong side orientation. Nevertheless, for the most common sizes and septa materials we offer them along with the appropriate empty caps. The septa shown is only suitable for PE caps N 20 (70266 nad 70267). Stoppers N 20 that generally come unassembled are also part of our offering. Please consider that the nominal diameter of the septa sometimes might be smaller than the ND of the cap due to the cap's wall thickness (e.g. N 12 septa are asembled in to N 13 screw caps).
