cryogenic tanks, liquid nitrogen dewars,gas 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...

Dewar flask , also known as dewar tank, is a double-walled glass vessel designed to store and transport liquid nitrogen or other cryogenic liquids. It is commonly used in industries such as scientific research, medicine, and cryogenics. The Dewar flask's vacuum insulation helps to maintain the low temperature of the stored liquid for an extended period, making it ideal for preserving biological samples, conducting experiments at low temperatures, and storing liquefied gases. The material of a Dewar flask is typically glass or metal, with a vacuum-insulated design. Dewar flasks come in various sizes and capacities, ranging from small portable ones for laboratory use to larger ones for industrial applications.
