Description
The Metaglas Sightglasses have an extreme compact construction and are suited for aspectic applications within the pharmaceutical industry. The Metaglas Type 99.NA Sight Glassses are designed to fit in NA-connection systems to offer clear visibility of the process.
The sight glasses are easy to install, have easy validation and connection for sterilization and cleaning. Next to this, the dead leag is eliminated by a standard ferrule connection, which is why air bubbles and unsolved trapped material is avoided.
Sight glasses from Metaglas are characterized by a sight glass that has been fused into a steel ring. The different expansion coefficients of glass and metal cause a compressive stress in the glass. The mechanical prestress commands a higher security compared to thermally prestressed glass; an unexpected rupture is fully excluded and the glass has an extreme resistance to shock and temperature. The sight glasses meet the requirements according to ASME BPE.
