Durometer (hardness of the septum)
Durometer is the hardness of a septum, expressed in ° shore. The higher the "shore" number, the harder the septum, the lower the "shore" number, the softer the septum. The softest sealing disc is 45 ° shore A and the hardest 70 ° shore A is hard. In addition to the thickness of the disc, the hardness is an important indicator, which septum is suitable for the penetration of a certain needles (sensitive needles, thin or thick needles, pointed or blunt needles, etc.).
