Manufactured with metal seal MFC’s and orbitally welded joints, Ultra High Purity (UHP) configured systems have minimal dead volume and maintain a low leak rate to prevent atmospheric contamination of gas calibration standards. An ideal option for those in the semiconductor, aerospace, research/biotech and advanced materials industries, with a >20 year history of designing and manufacturing highly reliable systems with low upkeep, long lifespan, and high repeatability and accuracy.

S4000 and S3000 gas mixing systems as well as S4040 gas dilution systems can be designed with UHP configuration, and UHP permeation ovens are available as an option.

• Low internal volume UHP metal seal valves.
• Leak tested to 1 X 10-9 ATM cc/sec He or better
• Orbitally welded and VCR (face seal) fittings with metal gaskets.
• Caps with lanyards on input/output ports (optional)
