Twinsburg, OH – November 29, 2018 – L.J. Star, Inc. (www.ljstar.com), the leading provider of process observation equipment, has introduced the exclusive MetaPlex^® Optical Grade Polymer Sanitary Window. Specifically designed for applications where glass is not the desired choice, the MetaPlex sanitary windows are formed by injecting the polymer into a precisely formed sanitary metal ring, which eliminates the dangerous weak point of the thin section that appears on competitors’ all-plastic windows.

The patent-pending MetaPlex windows provide a level of safety and useful service life well beyond that provided by conventional plastic sight windows. They are the only polymer sanitary window to withstand temperatures up to 134°C, operating temperatures to 100°C and operating pressures up to 150 PSIG. They also provide good chemical resistance to acids, alkalis (caustics) and alcohols. While other plastic sight glasses are meant for short term use during validation, process development and engineering applications, MetaPlex optical grade polymer sanitary windows are durable enough for use even in CIP and SIP cycles, eliminating costly down time.

“We identified a need in the marketplace for a glass-free sanitary window that could hold up to the precise standards of the food and beverage processing plants,” said company President David Star. “Our MetaPlex sanitary windows are designed with a proprietary interlocking seal against the clear polymer, so the process media only comes into contact with a single material. This is vital in sanitary service, as it eliminates crevices where contaminants can collect, and micro-organisms can grow. The MetaPlex polymer window is the only non-glass sanitary window on the market to offer a stainless-steel ring which eliminates the weak point that other plastic windows have.”

Some of the unique features of the MetaPlex sanitary windows include:

• The only optical grade polymer sanitary window on the market that offers a stainless-steel ring
• Extremely strong and chemically resistant to acids, alkalis (caustics) and alcohols
• The only polymer sanitary window that can withstand:
  • Temperatures up to 134°
  • Operating temperatures to 100°C and
  • Operating pressures up to 150 PSIG
• Glass-like transparency with enhanced safety
• Stronger than competitor units that are all-acrylic or polycarbonate
• The only non-glass sanitary window durable enough for use in CIP and SIP cycles
