Quartz tubes are essential components in many modern industries, especially those that demand high-purity materials, extreme temperature resistance, and optical clarity. Their versatility makes them suitable for everything from semiconductor processing to UV sterilization.

What Are Quartz Tubes?

Quartz tubes are cylindrical glass products made from high-purity fused silica (SiO?). Unlike ordinary glass, they can withstand high temperatures, resist chemical corrosion, and transmit ultraviolet and infrared light efficiently. Quartz tubes are available in various lengths, diameters, and wall thicknesses, and can be produced in both transparent and opaque forms.

Features of Quartz Tubes

Quartz tubes are valued for several unique properties:

• High Thermal Resistance – Can withstand temperatures up to 1100°C or more

• Thermal Shock Resistance – Tolerates rapid heating and cooling without cracking

• Chemical Stability – Inert to most acids and alkalis

• High Purity – Suitable for cleanroom and semiconductor environments

• Excellent Optical Transmission – Allows UV and IR light to pass through

What Are Quartz Tubes Used For?

Due to these features, quartz tubes are used in high-performance systems across multiple industries. They often serve as protective covers, reaction chambers, or structural parts in equipment that operates under extreme conditions.

Common Applications

Here are some of the most common and important applications of quartz tubes:

Semiconductor Industry

• Used in diffusion furnaces, oxidation tubes, and wafer processing systems

• Maintains purity in chip manufacturing environments

UV and Lighting Systems

• Quartz sleeves in UV sterilizers for water, air, and surfaces

• Essential in halogen and HID lamps due to their heat resistance

Laboratory and Furnace Equipment

• Reaction tubes in chemical and thermal experiments

• Protective casing for heating elements and thermocouples

Water and Air Purification

• Quartz tubes allow UV light to pass through while isolating the lamp from moisture

• Used in municipal, commercial, and home filtration systems

Medical and Environmental Devices

• Used in sterilization devices and phototherapy equipment

• Stable under intense light and heat exposure

Why Choose Quartz Tubes Over Ordinary Glass?

Quartz tubes outperform ordinary glass in several critical ways:

For industries where performance, safety, and precision matter, quartz tubes are the superior choice.
