Septa N 20, butyl/PTFE (Pharma-Fix), dark gray/gray, 3.0 mm, 50° shore A

Description

Replacement septa are not offered for all cap types and sizes, as manual assembly is not recommended due to the risk of contamination and possible incorrect side orientation. For the most common sizes and septum materials, however, we offer these together with the corresponding empty caps. The septum is a butyl/PTFE molded disc with only centric PTFE lamination, which therefore seals extremely tightly. It is temperature-resistant from -40 °C to 120 °C.
