O'Brien Analytical AT A GLANCE

For over 50 years, O'Brien has been supplying the petrochemical, refining, pulp & paper, and power industries with quality products based on the application of our heat transfer expertise. In process and emissions analysis 80% of problems occur in the sample transport system. O'Brien recognizes the fatal flaws of cold spots and unheated transitions from the collection point to the sample delivery in the sample conditioning enclosure. 

O'Brien TrueTube is a family of tubing products developed to provide best-of-breed performance in sample transport for process and emissions analyzers. O'Brien Analytical starts with select ASTM grade tubing and enhances its physical characteristics to improve dry-down, adsorption and corrosion resistance. We do this by controlling surface roughness, cleanliness, surface chemistry and reactive contaminants.
