Do not use per-chloric acid.
No organic solvents (alcohols, hydrocarbons, etc.) may be placed in the pressure vessels
or the microwave.
WARNING
Highly reactive substances which spontaneously react at higher temperatures or in the
presence of oxidizing agents or which may be nitrated and are potentially explosive may
not be digested in the microwave. Examples of such substances include: explosives
(TNT, etc.), perchlorates, ether, pyrophoric substances, etc.
Use only digestion vessels and spare parts authorized by Analytik Jena for use with the
TOPwave.
These can be obtained either from your local dealer or directly from Analytik Jena.
WARNING
Always wear safety glasses/goggles and protective gloves when working with the pres-
sure vessels!
Note any changes in the appearance of the p
ressure vessel which could indi
cate possible
material fatigue, e.g., deformation of the vessel, difficulty screwing on lids, etc. even
when the vessel is cold and not under pressure. All such vessels should be immediately
returned to
Analytik Jena for inspection.
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
vess
el 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! Al-
ways 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). Observe all relevant data
sheets and safety i
nstructions!
Never use more than one rupture disc per vessel!
Only use rupture discs which are designed for the respective vessel!
Always wear eye protection!
WARNING
Always wear safety glasses/goggles and protective gloves during work
which may in-
volve contact with chemicals, that is, when working with acids, pressure vessels, during
cleaning, etc.!
