NOTICE
The safety of the vessels is guaranteed by the rupture discs. Pressure and temperature
measurement serve to control the digestion process, but have no primary safety func-
tion.

Pressure Vessels and Rotor System
All vessels can be opened and closed tool-free. A rupture disc placed in the vessel lid li-
mits the interior pressure of all vessel types to the maximum permissible value for the
individual type. For all vessels, except PM 40, acid vapors that escape when the rupture
disc activates are guided to a collection system integrated in the rotor. Thereby the va-
pors are vented or suctioned off through the PFA tube connected to the swiveling lid.
PM 40 vessels are made entirely of TFM -PTFE. Aside from chemical resistance to all
mineral acids including hydrofluoric acid, this ensures a high level of mechanical
strength, even at high digestion temperatures.

PM 60 and PL 100 vessels are made entirely of TFM-PTFE. Aside from chemical re-
sistance to all mineral acids including hydrofluoric acid, this ensures a high level of me-
chanical strength, even at high digestion temperatures.
