Operation
Pressure Vessels!
Note any changes in the appearance of a pressure vessel which could
indicate possible material fatigue. Deformation of the vessel, difficulty
screwing on a lid and a melted or scorched appearance to the interior of
the vessel body all indicate damage. If a vessel lid is difficult to screw on
when the vessel is cold, this is due to a deformed lid or vessel. All such
vessels should be immediately returned to Perkin Elmer for inspection.
Never attempt to use excessive force to open the vessels.
Never use tools which do not come with the Titan MPS to open the
vessels!
Pressure vessels!
The pressure vessels are equipped with a rupture disc which produces a
spontaneous pressure release upwards through the gas containment
manifold when vessels experience excessive pressure. In rare cases,
pressure release may occur after the vessel has been removed from the
microwave oven.
Always make sure the vent opening on pressure
vessel faces away from both yourself and other individuals!
Hot gases may be released from the digestion vessel when it is
opened!
Only open the digestion vessel under a vent hood or other exhaust system.
Particular care is required when working with hydrofluoric acid (HF).
Observe all relevant MSDS and safety instructions!
Never use more than one rupture disc per vessel! This can cause a
dangerously unsafe condition with severely over pressurized vessels.
