What is ultra high purity tubing?

Ultra-high purity (UHP) stainless steel tubing is a type of tubing made from stainless steel that has an even higher degree of purity than standard high purity tubing. It is typically made with extremely low levels of impurities, such as sulfur, phosphorus, and carbon, and is often produced using specialized manufacturing processes and equipment. Ultra-high purity stainless steel tubing is commonly used in applications that require the highest levels of cleanliness and corrosion resistance, such as in the semiconductor, electronics, and biopharmaceutical industries. This type of tubing is often electropolished and may undergo additional surface treatments to ensure the highest level of purity and cleanliness.
