| Analytical spectroscopic methods such as XRF, OES, and IR often require samples in the form of round, flat-surfaced discs. Although sample discs can be cast from a fusion melt, they often begin as a powder and are pressed to shape in a pellet die.
For preparation of pellet samples, SPEX SamplePrep offers presses ranging in size from 12 tons to 30 tons of force and die sets for standard pellets of 13 mm, 31 mm, 35 mm, and 40 mm diameter, and Spec-Caps for protecting the finished 31 mm, 35 mm, or 40 mm pellet.
While methods and mills for pulverizing are as varied as the samples themselves, pellet pressing requires simpler tools. SPEX SamplePrep presses and dies are sophisticated in design, but functionally simple and rugged to provide years of maintenance-free service.
Reproducibility is a cardinal virtue in sample preparation. SPEX SamplePrep dies and presses ensure production of uniform sample discs, whatever the sample or analytical technique.
