What are speciality gases?

Speciality gases represent rare or ultra-high purity (g9.995% and above). Many industries, including analytical, pharmaceutical, electronics, and petrochemical, beneft from their unique properties, which help improve yields, optimize performance, and reduce costs.

Speciality gases, also known as high-purity or calibration gases, are gases produced with high levels ofpurity and used for specifc applications that require precise and controlled gas properties. These gasesare typically used in industries such as manufacturing, healthcare, electronics, scientific research, and environmental monitoring.

Dewar Cylinder

图片
DSW is a leading provider of liquid cylinders designed to safely contain a variety of liquefied gases, including nitrogen, oxygen, argon, and carbon dioxide. These gases are stored at incredibly low temperatures, maintaining a liquid state within the cylinders. The Dewar cylinders offered by DSW come in a range of sizes and capacities, providing flexibility to meet diverse storage requirements. One key advantage of DSW's liquid cylinders is their simplicity in infrastructure requirements and ease of maintenance and operation. This makes them a cost-effective choice for cryogenic storage needs, as they offer a practical and efficient solution for storing and transporting liquefied gases. Liquid argon tanks and cylinders are specifically engineered by DSW for the safe storage and transport of liquid argon, ensuring the integrity of the gas throughout the process. Similarly, liquid oxygen bottles provided by DSW offer a cost-effective alternative for cryogenic storage when compare

YDS dewar flask liquid nitrogen cylinder

Cryogenic dewar flasks are typically constructed with a double-walled design, with a vacuum-sealedspace between the inner and outer walls. This vacuum acts as a thermal barrier, preventing heat fromentering the flask and maintaining the low temperature inside. The inner wall is usually made of stainlesssteel or other materials with high thermal conductivity, while the outer wall provides structural supportand additional insulation. The space between the fences is often evacuated to further reduce heattransfer through conduction and convection. Additionally, some dewar flasks incorporate reflectivecoatings on the inner surface to minimize radiant heat transfer. The YDS liquid nitrogen cylinder is used in various industries such as biotechnology, healthcare, and research. It contains liquid nitrogen, which is a commonly used cryogenic fluid. Its main purpose is to store and transport biological samples, cells, tissues, and other materials at ultra-low temperatures to ensure their long

DSW is a leading provider in the cryogenic tanks market, offering our customers standard and custom-made accessories and storage for cryogenics worldwide. Our selection of containers - including tanks, dewars, and vessels - and valves and hoses of all sizes ensures the safe storage and transport of our cryogenic gases (LIN, LOX, LHe, LAr, LH2). Cryogenic storage tanks are designed to store materials at extremely low temperatures, typically below -150°C. These tanks can store a variety of substances, including gases (liquid nitrogen and liquid helium), as well as liquids such as liquid oxygen, natural gas, or hydrogen. Cryogenic tanks come in different types and sizes: Dewar flasks, Cryogenic liquid cylinders, Cryo storage tanks, ISO Tank Container, Semi-Trailer Tanker. Cryogenic storage tanks are the most significant and durable type of cryogenic vessels.Liquid Oxygen Tank: These tanks are used to store and transport liquid oxygen, which ismaintained at temperatures below -183 degrees
