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
with a preset minimum aging time of 16 hours.
OFITE Aging Cells are available in 260 mL and 500 mL sizes and utilize both
Viton
®
and Teflon
®
o-ring seals. Aging cells are typically constructed of stain-
less steel (grade 303 or grade 316) and are used for high-temperature testing
(up to 500°F / 260°C). For prolonged exposure to elevated salinity at high
temperatures (such as 20,000 mg/L chlorides at 350°F / 176.6°C), cells con-
structed from premium metals, such as Hastelloy
®
or Inconel
®
600 are avail-
able. The aging cell walls may be protected against corrosive fluids by using
the popular Teflon
®
liner (part no. 175-60), designed by OFITE. Refer to the
Teflon
®
liner instruction manual for more details.
For corrosion testing, a special 500 mL, 303 alloy stainless steel Corrosion
Test Cell is available with a modified inner cap designed to hold a corrosion
coupon. Also available in Hastelloy
®
upon request.
An optional calibrated rupture disk is available which can be installed in the
inner cap of the Aging Cells to rupture and release pressure at a predeter-
mined set point. OFITE can retrofit the rupture disk to existing cells.
