Quartz Tubes

We currently possess 8 quartz tube furnaces, with a daily production capacity of up to 12 tons of quartz tubes.

Milky Quartz Tube

The milky quartz tube has the advantages of being resistant to strong acids and bases, allowing for long-term use below 1050°C. It is widely used for quartz heating elements and is the most economical choice compared to other colors.

Various Colors Quartz Tubes

Transparent Quartz Tube

Transparent quartz tubes are made of high-purity (99.99%+) quartz glass, suitable for working temperatures up to 1600°C. They exhibit excellent uniformity, outstanding inertness, strong pressure resistance, and a broad absorption range.

Yellow Quartz Tube

Yellow quartz tubes enhance far-infrared transmittance, providing soft lighting suitable for indoor heating. Commonly used sizes include an outer diameter of 10mm and 12mm.

High-Strength Red Quartz Tube

This red quartz tube not only possesses the characteristics and beautiful color of regular ruby quartz tubes but also exhibits higher strength. It is the only quartz tube capable of withstanding impact tests of up to 0.5 J, whereas ordinary quartz tubes cannot endure impact tests exceeding 0.2 J.

Ruby Red Quartz Tube

Enchanting gemstone-red quartz tubes, commonly employed in heaters and oven heating.

Quartz Capillary Tube
