SPEX SamplePrep Spec-Caps are shallow, thin-walled aluminum cups which are routinely used in the production of pressed-powder sample disks for OES, XRF, and other analytical techniques. The Spec-Cap forms the bottom and sides of the finished pellet. Thus reinforced, sample disks are resistant to chipping and breaking, and are more easily handled, marked, and stored than unclad disks.
