With bromo-butyl / PTFE septa

Crimp and headspace seals ND20 are made of aluminium and are supplied with fitted septa made of a variety of materials. There are the following different types of caps available:

Plain caps with a 10 mm center hole. These caps are suitable for standard applications. They are available in several colours on request.

Clear lacquered caps, so called headspace caps, with a special score line that breaks when the internal pressure reaches 3.0 ± 0.5 bar. The excess pressure is then released, and the risk of the vial exploding can be avoided.

Clear lacquered centre tear-off caps and complete tear-off caps. These caps are available in several colours on request.

Gold lacquered, magnetic crimp caps with 5 mm centre hole to be used with CE HS500/HS800, CTC 500, as well as Fisons HS500 / HS800 instruments.

Gold lacquered, magnetic crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

Red lacquered, magnetic bimetal crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

These grey septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties. They are 3.0 mm thick and have a hardness of 50° shore A.
