TWINSBURG, Ohio, Oct. 4, 2011 /PRNewswire via COMTEX/ -- L.J. Star Inc., the leading provider of process observation equipment, announced a video that dramatically demonstrates the dangers of using a sight glass product that does not have thermal shock capabilities.

In just over a minute, the video shows what can happen when soda lime glass is exposed to thermal shock. It may shatter violently, creating a catastrophic failure and extreme safety hazard. On the contrary, L.J. Star's Metaglas® fused sight glass is made of borosilicate glass and, because it expands and contracts less with temperature fluctuations, it is far more thermal-shock resistant in industrial applications than soda lime sight glasses offered by other companies.

The Metaglas sight glass is made by fusing borosilicate glass to a duplex stainless steel ring in a unique manufacturing process that puts the glass into high compression. The result is a sight glass that has been described as having the transparency of glass with the strength of steel.

In addition, L.J. Star's Metaglas® fused sight glass is corrosion resistant, USP Type 1 compliant, and can withstand higher temperatures than sight glasses made of soda lime glass. These features are important for a clear view of processes, pharmaceutical and parenteral applications, steam-based cleaning, and long service life. Proven in thousands of installations, Metaglas is the #1 selling sight glass in the world.
