These fused quartz crucibles and lids consists of high-purity silica (SiO₂) with a purity level of 99,998%, making them valuable in research and industry.

• Optical transparency over a wide range
• Low thermal expansion
• Excellent thermal shock
• Resistance to large numbers of elements and compounds

These crucibles offer several unique properties that make it ideal in a variety of applications where other materials prove to be problematic. These properties include high purity, high softening temperature (1670 °C), optical transparency over a wide range.
