Flame-polished 99.99% clear fused quartz crucibles, lids, and evaporating dishes for ultra-trace acid digestion, phosphor firing, and thermal shock cycling.
Clear 4N fused quartz crucibles and evaporating dishes eliminate boron, sodium, and transition-metal leaching found in borosilicate glassware or clay-bonded ceramics. Capable of plunging directly from a 1,000 °C muffle furnace onto a cooling block—or even into cold water—without shattering, transparent quartz vessels streamline analytical chemistry, rare-earth oxide calcination, and high-purity salt/acid processing.
Available in tall-form and low-form crucibles with fitted ring lids, round-bottom pour-spout evaporating dishes, and heavy-wall laboratory quartz beakers.
