Highly transparent quartz glass perforated tube

Highly transparent quartz glass perforated tube is a precision quartz tube made of high-purity silicon dioxide (SiO ₂ purity ≥ 99.99%). By designing precise through-hole structures on the tube wall or inside the tube body, it achieves optical path transmission, gas/liquid flow guidance, or sensing protection. It has excellent UV visible light transmittance (≥ 93%) and ultra-high temperature resistance (long-term use at 1100 ℃ -1200 ℃), making it an ideal functional component in fields such as semiconductor, fiber optic communication, medical analysis, and scientific research experiments.

Product FAQ: The questions you are concerned about have answers here

Q: My laser equipment needs light protection in high temperature environments, and ordinary glass tubes are prone to bursting. What should I do?

Answer: Our highly transparent quartz glass perforated tube has an extremely low coefficient of thermal expansion (5.5 × 10 ⁻⁷/℃) and can withstand drastic temperature differences (from 1100 ℃ to room temperature without explosion), perfectly solving the problem of stable operation of equipment in high-temperature environments.

Q: In chemical analysis, it is necessary to transport multiple gases simultaneously without interfering with each other. How to select materials?

Answer: We provide customized porous (2-7 or even more) quartz tubes with micrometer level aperture tolerances to ensure independent laminar flow of multiple fluids. The quartz material is resistant to almost all acid and alkali corrosion except hydrofluoric acid, ensuring the purity and accuracy of experimental data.

Q: I need non-standard sized perforated pipes. Can I find the source factory to customize them?

Answer: Absolutely possible. As the source manufacturer, we provide full-size customized services ranging from outer diameter 0.5mm to 300mm and wall thickness 0.5mm to 15mm, supporting various special-shaped processing such as circular, square, D-shaped, triangular, and eccentric holes.

Core advantage: Redefine the standard for precision perforated quartz

Ultimate material purity and optical performance

We use high-quality fused silica raw materials with low hydroxyl content (below 5ppm). This not only ensures that the product has extremely high transmittance in the ultraviolet band (185-254nm), but also effectively avoids energy attenuation in laser applications. Its appearance is colorless and transparent, without bubbles, stripes, or scratches, and the pipe mouth has been finely polished.

Strict dimensional tolerances and hole control

By utilizing advanced laser drilling and precision drawing processes, we are able to control the aperture tolerance within a very small range (such as ± 0.05mm or ± 0.01mm). For porous structures, we ensure the parallelism and concentricity of each capillary tube, solving the alignment problem for users in fiber threading or microfluidic control.

Excellent high temperature and corrosion resistance characteristics

The softening point of quartz glass is as high as 1730 ℃, which enables our perforated tube to operate stably for a long time at a high temperature of 1200 ℃. Whether as a furnace tube for semiconductor diffusion furnaces or a protective sleeve for high-temperature thermocouples, it can exhibit extremely low deformation and excellent chemical stability.

Customer Application Cases

Case 1: A German medical laser equipment manufacturer

-Requirement: The customer requires a three hole quartz flow tube for beauty instruments, with extremely smooth inner walls to ensure non-destructive transmission of laser energy, and extremely high positional tolerances for the three holes.

-Solution: We use high-purity synthetic quartz material and control the outer diameter tolerance within ± 0.05mm through secondary drawing process. We also perform optical grade polishing on the inner wall and end face of the tube.

-Final effect: The customer feedback shows that this component significantly reduces the scattering loss of laser during transmission, increases the output energy of the device terminal by 8%, and greatly improves the heat dissipation performance of the device due to the high transparency of quartz material.

Case 2: Microfluidic Laboratory of a Renowned University in the United States

-Requirement: The research team requires a square outer wall and internal dual channel quartz capillary for the "droplet generation chip" to observe two-phase flow reactions.

-Solution: According to the drawings, we have customized a double hole quartz glass tube with an outer square and inner circle to ensure the flatness of the external light path observation, while the internal micropores achieve parallel injection of incompatible fluids.
