DURASITE® Constant Pressure Sample Cylinder Field-Proven Design, Reliable Results The DURASITE constant pressure sample cylinder is a portable sample vessel for transporting a liquid or gas hydrocarbon sample from its source to an analyzer. The cylinder design enables the product to be sampled and stored at pipeline conditions throughout the sample period and during final lab analysis. The patented design incorporates a free-floating piston to provide segregation between the product and pre-charge chambers. Once a pre-charge of inert gas has been applied to the DURASITE cylinder, constant pressure of the product can be maintained during sampling, transit and evacuation.
