How to Choose the Right Borosilicate Glass Product: Practical Selection Guide
Borosilicate glass is known for its excellent thermal resistance, chemical durability, and mechanical strength, making it a preferred material in laboratory equipment, industrial sight glasses, lighting, and food containers. However, selecting the right type of borosilicate glass requires a careful match between application needs and material properties. Here’s a practical guide:
1. Understand Your Application Environment
-
High-temperature conditions: For applications like reaction vessels or heating equipment, choose glass with a low thermal expansion coefficient and strong thermal shock resistance.
-
Corrosive environments: Opt for glass with high boron content, offering better resistance to acids and alkalis.
-
Mechanical stress: For pressure-bearing sight glasses or fluid pipelines, use thick-walled or tempered glass products with enhanced strength.
2. Focus on Dimensional Precision and Customization
For high-precision assemblies such as lab instruments or custom fittings, prioritize:
-
Tight dimensional tolerance (as precise as ±0.1 mm)
-
Special shapes or cuts (bent tubes, slots, or non-standard geometries)
-
Polished edges and drilled holes for safety and integration
3. Check Material Grade and Certifications
Choose borosilicate glass that meets relevant standards and regulations:
-
DIN ISO 3585 (standard for borosilicate glass 3.3)
-
RoHS / REACH compliance for environmental safety
-
Food-contact certifications like LFGB for consumer applications
4. Evaluate Supplier Capabilities
A reliable supplier should provide:
-
Full technical specifications and inspection reports
-
Application support and material selection advice
-
Rapid prototyping and scalable production options
Summary
Choosing the right borosilicate glass means aligning your application’s requirements with the material’s strengths. A successful selection balances performance, precision, and reliability, ensuring long-term efficiency and safety.
