Ultra-high purity (UHP) gases—rated 99.999% pure or greater—are essential for critical applications in welding, laboratory research, semiconductor manufacturing, and advanced material processing. UHP grades of argon, helium, nitrogen, hydrogen, and specialty mixtures deliver precise results in TIG and laser welding, fiber optics, gas chromatography, electronics, and cleanroom operations. Stringent purity standards eliminate contaminants that can compromise weld quality, analytical accuracy, or sensitive manufacturing. Our complete UHP gas portfolio is produced and analyzed to the highest specifications, and is offered in a range of cylinder sizes and delivery systems to meet specialized industrial and scientific requirements. Rely on proven expertise, rapid local delivery, and uncompromising quality in every cylinder.
