Glass Rods

Key Features of Borosilicate Glass Rods

• High Heat Resistance: Withstands extreme temperature fluctuations without cracking or breaking.
• Chemical Resistance: Resistant to acids, alkalis, and solvents, making them ideal for corrosive environments.
• Mechanical Strength: Robust and durable, capable of handling mechanical stress without shattering.
• Transparency: Crystal-clear optical properties — ideal for applications requiring visibility or light transmission.
• Low Thermal Expansion: Reduces thermal stress, ensuring long-term dimensional stability and integrity.

Common Uses

• Scientific Research: Heating, stirring, and handling samples in laboratory experiments.
• Glassblowing: A preferred material for forming intricate glass art and precision components.
• Art & Craft: Used in glass bead making, sculptural art, and decorative designs.
• Industrial Applications: Found in manufacturing processes such as electronics, optics, and medical devices.
• Everyday Products: Common in kitchenware (e.g., Pyrex) and high-performance laboratory glassware.

Benefits

• Durability: Long-lasting and resistant to physical and chemical wear.
• Versatility: Suitable for diverse applications across industries.
• Safety: Non-toxic and safe for use in laboratories and production facilities.
• Aesthetics: Visually appealing with a flawless, transparent finish.

Additional Options

40 mm OD and 50 mm OD rods are available and often used as base materials for small pressed glass items and precision components.
