Quartz-to-Pyrex Graded Seals

Quartz to Pyrex graded seals are commonly used in scientific and industrial applications that require hermetic sealing between Quartz and Pyrex glass components. These seals are specifically designed to join components made of quartz (silica glass) and Pyrex (borosilicate glass) due to their different coefficients of thermal expansion.

The graded seal design allows for a gradual transition in the coefficients of thermal expansion between quartz and Pyrex, minimizing stress and preventing the components from cracking or breaking when exposed to temperature changes. The resulting hermetic seal ensures reliable performance and longevity in demanding environments.
