Performing a Digestion
When assembling the vessel, visually inspect the metallic rupture disc. If there is
evidence of corrosion or other visible damage to the rupture discs, they must be
replaced.
A small bulge in the center of the rupture disc after use is normal and will not affect
its function. If this bulge exceeds 2mm in height or displays thinning at the edges
or top, it must be replaced.
Make sure the metallic rupture disc is properly centered and seated on the TFM™
seal with its edge sitting uniformly in the groove near the edge of the seal. Expand
the lip of the TFM™ seal using the included forming tool and then place the seal
with the rupture disc onto the vessel body. At this point, the cap can be placed on
the vessel and the vessel with sample is now ready to be placed in the Titan MPS.

Caution
Vessel minimum fill amount!
In each pressure vessel, no less than 5ml of liquid should be employed so
that the temperature sensor can determine the sample temperature
precisely.
The microwave oven requires a minimum load of approximately 20 mL of
liquid. The 20 mL minimum should be evenly spread amongst at least 4
vessels for each run in order to achieve the required total load. If the fluid
amount employed is too small, the oven may be damaged within a matter
of minutes! An inadequate liquid load can also result in rotor overheating
and in the worst case, rotor damage.
