Quartz slides and coverslips

These slides and coverslips are primarily used for microscopy applications where enhanced UV transparency is needed, such as for fluorescence microscopy. Other applications include requirements for improved optical performance, reduced light absorption, high temperature stability, chemical stability, and UV radiation transparency. Micro-Tec quartz microscope slides and quartz coverslips are made from type GE124 high purity fused quartz. This has been the choice of quartz for microscopy applications for many decades.

 Micro-Tec quartz slides are available in four sizes and the quartz coverslips in seven sizes with two different thicknesses. For improved optical performance please consider using 0.5mm thick coverslips as a substrate.
