Spex CertiPrep has developed a new line of pure and ultra pure fusion fluxes and additives.

The major benefit of these is the “micro bead” composition which eliminates the harmful dust that can clog the analytical instrumentation. The beads also help to cut down on weighing times and improve consistency, with each bead having the exact same ratio of components. The fluxes are conveniently pre-fused with additives for better accuracy and every batch is made to be exactly identical with no lot-to-lot variation.
