To meet the complex demands of modern glass applications, manufacturers rely on testing methods designed specifically for the unique behavior of glass materials. From float glass to laminated or tempered products, precise measurements of thermal, mechanical, and rheological properties are vital for ensuring structural integrity and visual performance. Advanced testing tools enable early identification of variations, streamline production workflows, and drive innovation across both industrial and architectural glass development.

• Consistent, accurate data: High-precision measurement for glass testing and architectural glass testing
• Early detection of variations: Identify process deviations and material inconsistencies quickly
• Production optimization: Leverage detailed measurement data to control and improve manufacturing processes
• Supports material innovation: Equip your R&D with tools for advanced analysis and development

Precisely measure the viscosity and flow properties of glass across a broad temperature range. Our instruments enable you to:

• Analyze the effects of temperature and cooling rates on viscosity, helping to optimize forming, shaping, and refining processes in both optical and high-melting glass types
• Identify crystallization and devitrification points, supporting efficient process control and minimizing defects during production
• Establish glass reference materials by ensuring batch homogeneity, crucial for large-scale manufacturing consistency
