About Epic Crystal Co., Ltd. - Electric Components Supplier in China

Epic Crystal Co., Ltd. is based in China and currently lists five active scintillator products. The catalogue falls under the electric components category, specifically radiation detection crystals. These products are identified by their material composition such as bismuth germanate (BGO) and lutetium‑yttrium oxyorthosilicate (LYSO). In international trade, scintillator crystals are classified under HS chapter 90 to 92, commonly reported with HS code 9022.99 for other measuring instruments. Buyers typically import these items to markets in North America, Europe and East Asia for medical imaging, security scanning and high‑energy physics applications.

The listed items include BGO scintillator, LYSO scintillator, thallium‑doped cesium iodide, thallium‑doped sodium iodide and cerium‑doped lanthanum bromide. Each crystal type offers distinct density and light‑yield characteristics; for example BGO has a density of about 7.13 g cm⁻³ while LYSO reaches a light yield near 32 000 ph MeV⁻¹. Thallium‑doped iodide crystals are widely used for gamma spectroscopy because of their high photon‑count efficiency. Cerium‑doped lanthanum bromide provides sub‑3 % energy resolution at 662 keV, a benchmark in high‑resolution spectroscopy. These specifications are standard reference points that buyers compare when evaluating supplier quotations.

Product Range and Specialties of Epic Crystal Co., Ltd.

Epic Crystal’s catalogue comprises five scintillator crystals: BGO, LYSO, thallium‑doped cesium iodide, thallium‑doped sodium iodide and cerium‑doped lanthanum bromide. In the scintillator market, BGO is valued for its high density (7.13 g cm⁻³) and radiation hardness, while LYSO is prized for its fast decay time (~40 ns) and high light output. Thallium‑doped cesium iodide (CsI(Tl)) and thallium‑doped sodium iodide (NaI(Tl)) are standard for low‑energy gamma detection, typically supplied in cylindrical form with diameters from 25 mm to 76 mm. Cerium‑doped lanthanum bromide (LaBr₃:Ce) is classified as a high‑resolution crystal, often offered in dimensions up to 50 mm × 50 mm and requiring hermetic sealing due to hygroscopicity.

Industry practice groups scintillator grades by light yield (ph MeV⁻¹), decay time (ns), density (g cm⁻³) and intrinsic energy resolution (% at 662 keV). Buyers often request data sheets showing these parameters together with impurity levels (ppm) and surface finish (polished vs. rough). Typical packaging includes vacuum‑sealed, moisture‑controlled containers inside double‑wall cardboard, sized for 20‑ft or 40‑ft containers depending on order volume.

Trade and Export Information - Epic Crystal Co., Ltd.

China is a major exporter of inorganic scintillator crystals, with the United States, Germany and Japan representing the largest import destinations. HS chapter 90 to 92, especially code 9022.99, is used for customs declaration of these measurement instruments, and customs authorities frequently ask for conformity certificates such as ISO 9001 or IEC 60598 for related equipment. Importers usually require a material safety data sheet (MSDS), a certificate of analysis (CoA) and, for European buyers, compliance with REACH registration of hazardous substances.

Logistics for scintillator crystals favor temperature‑controlled, low‑vibration shipping; most suppliers ship in wooden crates with foam inserts and desiccant packs. Common Incoterms are FOB Shanghai or CIF Hamburg, allowing buyers to manage insurance and freight according to their supply chain preferences. Export documentation often includes the test report for light yield, energy resolution and dimensional tolerance, which facilitates smoother clearance in the destination country’s regulatory environment.

Sourcing from Epic Crystal Co., Ltd. - Buyer Guidance

When sourcing from Epic Crystal, buyers should request the latest test report that details light yield, decay time, energy resolution at 662 keV and impurity concentrations for each crystal type. Verification of ISO 9001 certification or an equivalent quality management system is advisable, as it signals adherence to documented manufacturing controls. Samples are typically supplied in standard dimensions (e.g., 25 mm × 25 mm × 10 mm) and packaged in moisture‑proof containers; confirming the packaging method helps prevent hygroscopic damage before integration into detection systems.

Buyers should also confirm the crystal’s surface finish, tolerance on dimensions (often ±0.1 mm) and the presence of any protective coatings. For large orders, request a batch‑level certificate of analysis and, if required by the destination market, a conformity statement to IEC 60598 or REACH. Clarifying the minimum order quantity, lead time (commonly 4‑6 weeks for custom cuts) and preferred Incoterm will streamline the procurement process.
