J.G. Finneran's Ultra Low Bleed Aluminum Seals and 9mm R.A.M.™ Caps are lined using LCMS high purity septa. 

The ultra low bleed septa are ideal for very sensitive applications such as Mass Spec or when multiple injections are required.  Our Ultra Low Bleed Septa eliminates particulates with no interfering peaks.  Aluminum seals are available in 11mm and 20mm crimp finish. The 9mm R.A.M.™ short thread closures with a smooth or ribbed finish, are available with either a friction fit or bonded ultra low bleed PTFE/Silicone Septa.
