The CX 100 consists of TFM-PTFE pressure vessel, ceramic pressure jacket, TFM-PTFE –
inline, a TFM-PTFE lid and a Titanium-rupture disc. The PP rotor can hold up to 8 CX
vessels.
After the sample material and the acids have been added in the TFMTM insert (li-
ner) it is advisable to leave the digestion vessel open for approx. 10-20 min so that
reactions already taking place can sub-side.
Thereafter the TFM insert (liner) is locked by means of the TFM lid. Considerable re-
sistance must be tangible here. If this is not the case, the sealing lip must be dilated
again as described above.
The locked TFM liner is now inserted into the CX 100 pressure digestion vessel toge-
ther with the ceramic pressure jacket.
The titanium rupture disk is now placed on the locking lid and the digestion vessel
locked by means of the coupling cap. It is sufficient to lock it hand-tight without
exerting any additional pressure.

Fit the rotor symmetrically
(see section "Positioning of the vessels in the rotor" p. 77).
Screw the vent fitting onto the associated collection vessel tube (it may be necessary to
first move the vessel into the proper position). Seal any unused positions on the
