Quartz glass sight glasses

Product catalog summary

Usage
Quartz glass sight glasses are designed for visual process control under high thermal and chemical stress. Made from high-purity quartz glass (99.98% SiO₂), they provide excellent UV transmission and high chemical resistance, making them ideal for high-temperature applications in process engineering, analytics, or laboratory environments.

Operating Conditions
These sight glasses undergo production and quality checks to ensure property values and tight dimensional tolerances, making them suitable for extreme conditions.

Optical Properties
The spectral transmission ranges from 190 to 4977 nm at a thickness of 1 mm.

Delivery Forms and Dimensions
Available in various designs such as round, elongated, square, as a tube, or custom-made according to requirements or drawings.

Quartz glass sight glassesfor sight glass fittings, round/longitudinal/square/ ©f Use our transmission calculator for quartz glass! Quartz glass sight glasses are ideal for visual process control under high thermal and chemical stress. Made of high-purity, natural quartz glass (99.98% SiO2), they offer excellent UV transmission as well as exceptionally high chemical resistance. Thanks to their temperature resistance, they are particularly suitable for high-temperature applications - such as in process engineering, analytics, or laboratory environments. Optical Properties The graph next to it shows the spectral transmission from 190 -4977 nm at a thickness of 1 mm. We supply high-quality sight glasses made from natural or synthetic quartz glass in various designs: round, elongated, square, as a tube or in custom-made designs - just according to your requirements or according to drawing. 17092025 - Subject to technical changes and errors!
