Accurately distinguishing between quartz tubes and ordinary glass tubes is the key to ensuring experimental safety and production yield in the fields of industry and scientific research. Although the appearance of the two is similar, the core difference lies in the purity of silicon dioxide: the purity of quartz tube is over 99.9%, with excellent high temperature resistance and ultraviolet transmission performance; However, ordinary glass tubes contain impurities of fluxing agents, have poor heat resistance, and block ultraviolet rays. Mastering scientific identification methods can effectively avoid safety hazards caused by material misuse.

As a professional quartz product customization manufacturer, Luverre Quartz deeply understands the decisive impact of material selection on end use applications. Our products are designed to solve technical challenges under extreme working conditions, whether it is to cope with the ultra-high temperature environment in semiconductor manufacturing or the strict requirements for high transmittance in optical instruments, we can provide perfectly adapted solutions. We are committed to providing customized quartz products with full specifications and multiple scenarios to help global customers break through process bottlenecks, enhance product added value and production efficiency.

Scientific Identification: Core Differences between Quartz Tube and Ordinary Glass Tube

To ensure the professionalism and accuracy of material selection, it is recommended to conduct an objective evaluation from the following four dimensions:

Composition and purity differences: Quartz tubes are made of high-purity silicon dioxide (SiO ₂) with a molecular structure stability of over 99.9%; Ordinary glass is a mixture of silicon dioxide and additives such as sodium oxide and lead oxide, with relatively low purity.

High temperature resistance and thermal stability: The softening point of quartz tube is as high as 1730 ℃, and it can be used for a long time at 1100 ℃. Its thermal expansion coefficient is extremely low, and it can withstand severe temperature differences without bursting; The softening point of ordinary glass is usually around 800 ℃, and it is extremely prone to breakage when subjected to rapid cooling and heating.

Optical transmission performance: In the ultraviolet range of 200-300nm, quartz tubes have extremely high transmittance (greater than 70%), making them the only choice for UV sterilization, curing, and spectral analysis; Ordinary glass is almost completely opaque to ultraviolet light due to impurities.

Professional instrument detection method: The most authoritative way of identification is to use a spectrophotometer. At a wavelength of 250nm, after zeroing with air as a blank, it is placed in an empty tube for testing. If the absorbance is less than 0.07Abs, it is a quartz tube, otherwise it is a regular glass tube.

Full specification customization services and application empowerment

We provide customized quartz products with various outer diameters, wall thicknesses, and length sizes to meet the special needs of different industries. With high-purity raw materials and precise processing techniques, our quartz products are not only resistant to strong acid corrosion (except hydrofluoric acid), but also maintain extremely high chemical inertness, ensuring that no ions or pollutants are precipitated into the sample in high temperature or high cleanliness environments, fully guaranteeing the integrity and safety of the process flow.

Why Choose Us: Targeting Application Challenges and Customer Cases

In practical applications, many enterprises often face challenges such as deformation of high-temperature furnace tubes and rapid attenuation of ultraviolet light sources. We have successfully resolved these challenges for numerous clients through our profound technical accumulation.

Customer application case: A large environmental protection water treatment engineering enterprise

The company is facing severe technical challenges when developing a new generation of large-scale ultraviolet water disinfection equipment: traditional ordinary glass sleeves are prone to light transmittance attenuation and aging rupture under long-term high-intensity ultraviolet irradiation and water flow impact, resulting in a significant decrease in sterilization efficiency, and frequent replacement increases high maintenance costs. After receiving the request, we customized high-purity ozone free quartz tubing for it. Thanks to our excellent UVC band transmittance (≥ 90%) and outstanding thermal shock and water pressure resistance, the new casing not only ensures efficient output of ultraviolet energy, but also maintains long-term structural stability in complex outdoor water treatment environments. In the end, the equipment successfully passed various rigorous tests and was successfully put into commercial use, completely solving the problem of sterilization decay and greatly improving the overall efficiency of the system.
