Magnetic precision thread cap ND18, silver, 8 mm hole, septum Silicone white/PTFE red, Ultraclean, 45° shore A, 1.3 mm, pack of 100, LABSOLUTE®, Art. No. 18 03 1578

Precision thread screw seals ND18 are made of metal and supplied with fitted septa made of a variety of materials. The hole size is selected so that the cap is suitable both for SPME and headspace applications. However, enough surface is left for the magnet to be able to transport a completely filled vial. The screw-on mechanism ensures that the cap always has a flat surface so that the bottle cannot fall from the magnet. Separation of the vial and cap for disposal after analysis is much easier than with crimp caps. Closed caps in combination with precision thread screw vials ND18 are ideal for sample storage.

Septa are temperature-resistant from -60 °C to 200 °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.
