Safety Practices
Pressure vessels!
Never attempt to use force to open the vessels. Never use tools to open
the vessels!
The pressure vessels are equipped with a rupture disc which
produces a spontaneous pressure release upwards through the screw-on
tube connections in case of excessive vessel pressure. In some cases, such
a spontaneous pressure release may occur after the vessel has been
removed from the microwave oven.
Hot gases and vapors may be released from the digestion vessel when
it is opened!
Always make sure the vent opening on pressure vessels
faces away from both yourself and other individuals!
Only open the digestion vessel under a fume hood or other exhaust
system.
Particular care is required when working with hydrofluoric acid (HF).
Due to the extreme damage it inflicts. Observe all relevant data sheets and
safety instructions!
Note
Replace the vessels after around 5000 digestions to maintain reliable
operating conditions and to prevent negative influences on your analysis
results (e.g. memory effects etc.). Perkin Elmer includes its digestion
vessels in the one year warranty coverage. Nevertheless all of the vessels
are subject to a certain aging process, which also depends on the type and
frequency of the application. Typically the service life is 5,000 digestion
processes or at least 3 years.
