Aluminium cups for pressing

Spex SampePrep® Spec-Caps® are shallow, thin-walled aluminium 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.
