• To change the filter, follow the opposite proce-
dure: press the filter to the right, then pull it to
the left and out of the tube.
• The filter must be changed approx. every
3 months (we recommend writing the date on
the filter using a marker).
The filter must be disposed of accord-
ing to valid laboratory specifications.
If completely defrosted, bacterial
filters and filter bags MUST be re-
moved, as melted coverslip mountant
clogs the extraction line. The bacterial
filter absorbs the moisture during
defrosting and becomes unusable!
• Set the mark (A) of the extraction opening to
open (1) and pull it out. Plug the filter (3) into
the extraction hose connecting piece (3a) un-
til there is an audible click.
Now push the connected parts back into the
opening in the cryostat chamber (filter first) and
set it to the "closed" mark (2, Fig. 27).
When not using the extraction, tightly
close the opening for the extraction
hose using the silicone stopper (E)
included in the scope of delivery.
Reasons:
1. To prevent section waste from falling into the
opening.
2. To prevent cold from escaping from the
chamber.
3. To prevent moisture from penetrating the
chamber.
