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