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-term preservation and quality during storage and transportation.

Argon gas cylinder

Argon gas is a colorless, odorless, and inert gas that makes up about 1% of the Earth's atmosphere.

It is a noble gas and is commonly used in various applications such as welding, lighting, and as a shielding gas in industrial processes. Argon is also used in laboratories for various analytical purposes.

The purity of argon gas can vary depending on its intended use. In industrial applications, argon gas is typically available in various purity levels, with common purities ranging from 99.99% to 99.9999% (4.0 to 6.0 grade).

The purity of argon gas is a measure of the percentage of argon present in the gas mixture, with higher purity levels indicating a lower concentration of impurities.

High-purity argon gas is often required for applications such as semiconductor manufacturing, where even trace amounts of impurities can affect the final product.
