Fused Sight Glasses: Reliable Observation Solutions Designed for Demanding Conditions

In environments with extreme pressure, vacuum, or significant temperature fluctuations, traditional sight glasses often struggle to meet long-term sealing reliability requirements. Borlan’s metal-to-glass fused sight glasses permanently bond stainless steel and glass through specialized processes, completely eliminating the leakage risks associated with sealing gaskets. This innovative design allows them to withstand a wide temperature range from cryogenic to high heat, as well as high-pressure and vacuum conditions. They are particularly suited for fields with stringent sealing requirements, such as biotechnology and fine chemicals. Leveraging years of manufacturing experience, we provide tailor-made fused sight glasses to ensure reliable and durable process monitoring even in the most demanding applications.
