With silicone / aluminium septa
Screw seals ND15 are made of PP and are supplied without or with fitted septa made of a variety of materials. They have a 15-425 thread, a 9 mm centre hole or are closed.
Screw seals ND18 are made of PP and are supplied with or without fitted septa made of a variety of materials. They have a 18-400 thread, a 12 mm centre hole or are closed.
These ND18 screw caps with 18-400 thread are not compatible with ND18 precision thread vials !
These septa are temperature-resistant from -60 °C to 220 °C and have better purity than septa made of natural rubber or red rubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications. The silicone is fully coated with a silver aluminium foil.
ND15 seals are suitable for items 7.616 898, 7.618 935, 7.616 655 and 7.618 936.
