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 Teon®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 uids by using
the popular Teon®liner (part no. 175-60), designed by OFITE. Refer to the
Teon®liner instruction manual for more details.
For corrosion testing, a special 500 mL, 303 alloy stainless steel Corrosion
Test Cell is available with a modied 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 retrot the rupture disk to existing cells.

Specications Maximum Temperature: 500°F (260°C)
Maximum Pressure: 2,000 psi (13.8 MPa)
For tests above 200°F, refer to the chart below for the appropriate pres-
sure.
Do not use nitrous oxide cartridges as pressure sources for high-
temperature, high-pressure (HTHP) aging. Under high temperature and
pressure, nitrous oxide can detonate in the presence of grease, oil, or
carbonaceous materials. Nitrous oxide cartridges are to be used only
for Garrett Gas Train Carbonate Analysis.
Carbon dioxide and nitrous oxide cartridges are pressurized to approxi-
mately 900 psi at 1 atmosphere (sea level). Therefore, they should never
be transported by airplane without proper packing because cabin de-
pressurization may cause an explosion.
If the aging cells are going to be rolled in a roller oven during a test,
install o-rings on the outer perimeter on the top and bottom of the cells.

Cell Corrosion
Test uids under high tempreature and pressure can corrode the cell body
and caps. Carefully inspect the cell body and calls for corrosion before and
after each test.
Some materials are more susceptible to corrosion than other. Also, some
uids and additives are more corrosive than others. OFITE offers a variety of
cell materials for different levels of corrosion resistance and cost.

Operation 1. Carefully inspect the o-ring for defects and place it in the groove in the
cell body. Replace the o-ring if it is hard or has cuts and nicks. Blow air
through the valve stem to make sure it is not plugged.
O-ring
2. Determine a safe volume and safe initial pressure for the temperature at
which the sample will be tested (refer to the chart on page 5). Place
the correct volume of uid into the cell. Be careful not to get uid in the
o-ring groove or on the o-ring.
Donotoverllthecell.
3. Clean any spilled uid from the edge of the cell and place the inner cap
on top of the cell body o-ring so that it seats in place. Hand tighten the
outer cap in place. Using the Allen wrench, tighten the set screws in the
outer cap. Insert the valve stem with the o-rings in place into the inner cap
and tighten completely. Loosen the valve stem approximately one half
turn before pressurizing.

4. When the desired pressure is reached, close the valve stem by tightening
it with a wrench. To ensure there are no leaks, immerse the cell in water
and check for any bubbles coming from the valve stem or cell cap.
5. Place the Aging Cell inside the oven and adjust to the desired tempera-
ture.
6. After the desired aging time has elapsed, remove the cell from the oven
and allow it to air cool until the sample temperature is 300°F (149°C) or
less. The cell may then be either air or water cooled.
The sample temperature must be equal to the ambient temperature
before you release the pressure and open the cell.
7. Loosen the set screws, unscrew the outer cap, and remove the inner cap.
8. Clean out the valve stem with water. Blow air through the stem to remove
any residual water.
9. Observe the aged uid and record the condition as “uid”, “gelled”,
“plastic”, “hard”, etc. You may also want to test for viscosity, shear or gel
strength, or ltration control.
10. Thoroughly clean the entire cell with soap and water.

Maintenance Regular maintenance will extend the useful life of the aging cells.
After every test:
1. Thoroughly clean and dry all components including the cell body,
inner cap, outer cap, valve stem, and o-rings.
2. Inspect all o-rings for damage or wear. Discard any that are nicked,
cracked, or distorted from their original shape. Replace them with new
o-rings.
3. Apply grease to the threads on the outer cap and cell body.
Every three years (yearly for highly corrosive conditions):
1. Sand blast the metal components (cell body, inner cap, outer cap).
2. Visually inspect the cell body and inner cap for pitting or other signs of
corrosion. If any material loss is present, replace the damaged com-
ponent.
3. Inspect the threads on the outer cap and cell body for burrs.
4. Replace all o-rings and apply grease to the threads on the outer cap
and cell body.
5. Pressure test with water up to 4,000 psi.
OFITE offers aging cell recertication that includes all of the above plus a
one-year certicate. Contact your sales representative for more information.
