Septa, 11 mm
The choice of the right septa depends on the application. Many septa are PTFE coated on one side. PTFE is highly resistant against many chemicals and forms an inert border between the sample and the base material of the septa.
The septa's base material has various physical and chemical properties, like temperature resistance, resealability, cleanliness, hardness and thickness.
Septa with a double-sided PTFE coating show a very low particle formation during penetration.
