The OFITE Aging Cell is a patented (U.S. Patent No. 4,805,443) pressure vessel that enables samples to be subjected to temperatures higher than the boiling point of water and still be maintained in a liquid state. The cells may be used for static temperature exposure or in a dynamic mode in a roller oven.

Aging Cells are available in three sizes: 260 mL, 500 mL, and 1000 mL.  They are typically constructed of grade 303 or 316 stainless steel and are used for high temperature testing (up to 600°F). For prolonged exposure to highly corrosive test fluids, cells constructed from premium metals, such as Hastalloy® or Inconel® 600 are available.  The aging cell walls may also be protected against corrosive fluids by using the Teflon® liner.

For corrosion testing, a special 500 mL Corrosion Test Cell is available.  It has a  modified inner cap designed to hold a corrosion coupon suspended in the test fluid.

An optional calibrated rupture disk is available, which can be installed in the inner cap to rupture and release pressure at a predetermined set point.
