4x40mm Borosilicate Glass Rod with Good Thermal Shock Resistance

This 4x40mm borosilicate glass rod combines excellent thermal shock resistance with high light transmittance and chemical durability. With a low thermal expansion coefficient, it withstands sudden temperature changes without cracking, making it ideal for laboratory stirring, optical light guiding and equipment support applications.

Product Parameters

Key Features

• Good Thermal Shock Resistance – Low thermal expansion borosilicate glass withstands sudden temperature changes without cracking or shattering, safe for heated laboratory operations.
• Chemical Durability – Resistant to common acids and alkalis used in routine laboratory and chemical processing environments.
• High Light Transmittance – Excellent optical clarity for light guide and positioning pillar applications inside optical instruments.
• Cost-Effective Performance – Superior thermal and chemical properties compared to soda-lime glass at a competitive price point.

Applications

1. Laboratory Use

Stirring rod and reaction support component for routine chemical experiments with common acid and alkali reagents and short-duration high-temperature heating.

2. Optical Equipment Accessories

Small light guide pillar and internal positioning transparent support for optical instruments and measurement devices.

3. Industrial Equipment

Equipment observation window support, small sealed transparent pillar, and heat-resistant accessory for small appliances.

4. Chemical Processing

Small corrosion-resistant positioning component and simple anti-corrosion guide accessory for chemical processing applications.

Advantages over Soda-Lime Glass

Compared to ordinary soda-lime glass, this borosilicate glass rod offers superior thermal stability—resisting cracking under sudden temperature changes—better resistance to weak acids and alkalis, and higher light transmittance, all at an excellent cost-performance ratio.
