High-purity krypton (Kr) gas supplied from China for lighting, electronics, and medical applications.
High-purity krypton (Kr) gas for high-efficiency lighting, insulation glazing, semiconductor manufacturing, and medical diagnostics.
Krypton is a colorless, odorless, non-toxic, and non-flammable noble gas, known for its high density, low thermal conductivity, and high luminous transmittance. As a rare atmospheric gas, it exhibits excellent light emission properties when electrically stimulated, offering higher luminous efficiency and longer lifespan than argon-filled bulbs. Krypton serves as a filling gas for high-performance lighting, mining lamps, off-road vehicle lights, and airport runway indicator lights. It is also widely used in insulation glazing, semiconductor manufacturing, medical diagnostics (cerebral blood flow measurement), and as a tracer isotope in leak detection and thickness measurement applications. Krypton-86 has been used as an international length standard, typically transported as a liquefied compressed gas.
Global Shipping & Export Compliance
Krypton (UN 1056) is classified as a non-flammable compressed gas and must be handled under strict hazardous materials regulations.
- Sea freight (FCL / LCL) – standard export method
- Air freight – available with regulatory compliance
Required Export Documents
- Material Safety Data Sheet (MSDS)
- Certificate of Analysis (COA)
- Dangerous Goods Declaration (DGD)
- UN-certified cylinder documentation
- Commercial invoice & packing list
How to Order Krypton Gas from China
- Send technical requirements (purity, pressure, application)
- Receive quotation (EXW / FOB / CIF options)
- Confirm cylinder specification & compliance
- Review COA, MSDS, and certification documents
