WARNING
Risk of chemical burn!
Use only digestion vessels and spare parts authorized by Analytik Jena for use with the
TOPwave.
Always wear safety glasses/goggles and protective gloves when working with the pres-
sure vessels!
Note any changes in the appearance of the pressure vessel which could indicate 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.
The lip seal on the collection system should be occasionally replaced.
Unscrew the fixation screw on the collection vessel.
Exchange the lip seal for a new one.
Fasten the fixation screw finger-tight again.
