SpeedExtractor E-916/E-914 Operation Manual, Version D
C Keep the sealing surfaces clean
Insert the upper cellulose g (P/N 049572 for
E-916, 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 plunger 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.
