(P/N 049572 for E-916, P/N
11069533 for E-916XL, P/N 051249 for E-914) or glass
fiber filter (P/N 11057189 for E-916, P/N 11057190 for
E-914) carefully uniformly into the cell using the plung-
er
h
. The top glass fiber filters are recommended for
trace and ultra-trace analysis. Again, visually inspect the
cell for remaining grains above the filter and make sure
that the filter is in full lateral contact with the cell.
NOTE
Do not attach any labels to the cell! The dimensions of
this assembly have been optimized to provide optimal
and uniform heat transfer from the heating block to
the extraction cell. Additionally, the high temperatures
might damage the label. For unambiguous sample
identification, every single extraction cell is etched
with a serial number.

NOTE
Be sure to clean the sealing surfaces at the top and the bottom carefully, i.e. the offset and the surfaces above it.
Use the brushes for that purpose. Any remaining sample or grain of sand reduces the lifetime of the cup seals and
the extraction cells significantly. In case of proper operation the seals last for 100 extraction runs.
