Borosilicate Glassware for Industrial Process & Laboratory Applications

Industrial Borosilicate Glassware — Process Equipment & Laboratory Grade

Borosilicate glassware encompasses the full range of industrial and laboratory glass components manufactured from borosilicate glass 3.3. From sight glass discs and gauge glass strips to process tubes and observation windows, borosilicate glassware is the material of choice wherever thermal stability, chemical resistance, and optical clarity are required simultaneously.

Key Properties

• Thermal shock resistance: withstands rapid temperature changes (ΔT up to 120°C)
• Maximum continuous operating temperature: 450°C
• Chemical resistance: Class 1 hydrolytic resistance (ISO 719); resistant to acids, alkalis, and solvents
• High optical clarity for accurate visual process monitoring
• Low coefficient of thermal expansion: 3.3 × 10⁻⁶/K
• Compliant with DIN 7080, DIN 7081, ISO 3585

Industrial Applications

• Sight glass discs and windows for pressure vessels and reactors
• Level gauge glass strips (reflex and transparent types)
• Borosilicate glass tubes for tubular level gauges
• Process observation windows in chemical and petrochemical plants
• Pharmaceutical manufacturing equipment (GMP-compliant)
• Food and beverage processing sight glasses

Available Product Forms
