UV-stop quartz tube
The UV‑stop quartz tube offered by Dongxin Quartz Products Co., Ltd. is manufactured from high‑purity fused silica glass with a silica content greater than 99.9 %. The tube incorporates a CE‑doped composition that blocks ultraviolet radiation, making it suitable for environments where UV protection is essential. While the supplier lists multiple sizes, the exact dimensions are not specified, so buyers should request length and outer‑diameter data that meet their system requirements.
Fused silica is the standard material for high‑performance optical components because of its low thermal expansion and high transmission in the visible spectrum. Typical quartz tubes in this category have outer diameters ranging from 10 mm to 50 mm, wall thicknesses of 1‑3 mm, and transmission rates above 95 % for wavelengths between 400 nm and 700 nm. The material’s thermal shock resistance usually exceeds 500 °C, allowing use in processes involving rapid temperature changes.
These tubes are widely employed in semiconductor processing equipment, UV‑curing devices, optical instrumentation and medical apparatus that demand UV‑radiation shielding. Importers targeting laboratories, clean‑room manufacturers or equipment assemblers should verify the tube’s UV‑blocking efficiency and confirm that the product conforms to relevant glass‑product HS classifications. Trade terms such as minimum order quantity, packaging style and incoterm are not disclosed, so direct negotiation with Dongxin Quartz Products Co., Ltd. is required.

| UV‑blocking feature | CE‑doped glass composition (typical for UV‑stop applications) |
| Typical outer diameter | 10‑50 mm (typical range) |
| Typical wall thickness | 1‑3 mm (typical) |
| Visible light transmission | ≥95 % (typical for high‑purity silica) |
| Thermal shock resistance | up to 500 °C (typical) |
| Typical length options | 100‑500 mm (typical) |
| Weight per metre | ≈2.2 kg/m (typical for fused silica) |

Sourcing UV-stop quartz tube from Dongxin Quartz Products Co., Ltd. - China Import Guide
Importers should first confirm that the quartz tube meets the required UV‑blocking performance by requesting a spectral attenuation report and a material purity certificate. Verifying compliance with relevant glass‑product standards and any regional safety regulations will reduce the risk of non‑conformance during installation.
Shipping from Dongxin Quartz Products Co., Ltd. is usually arranged via the Lianyungang seaport. Buyers need to agree on an Incoterm - commonly FOB or CIF - and obtain an estimated lead‑time, which the supplier does not publish openly. Accepted payment methods typically include T/T, L/C or escrow, and these terms should be defined in the sales contract before payment is made.
To ensure product quality, arrange a third‑party inspection that checks dimensional tolerances, UV‑blocking efficiency and surface integrity. Request the supplier’s ISO 9001 or equivalent quality‑management certification, as well as a full packing list, commercial invoice and certificate of origin to facilitate smooth customs clearance and downstream quality assurance.
