5.1 Cleaning
Do not use acetone or xylene to clean the lacquered surfaces of the
instrument.
The cryochamber should be cleaned in regular intervals, especially
when large quantities of sectioning debris have been produced during a
work session.
Since sectioning debris (especially very soft rubber samples, such as
bitumen) melts during the chamber heating process, we advise you to
clean the chamber prior to the heating process (however, after all re-
maining LN

has evaporated / the chamber has reached ambient tem-
perature) with a vacuum cleaner or similar tool.
5. Cleaning and maintenance
For cleaning, proceed as follows:
• Remove knife, knife holder, specimen holder
and cold bridge.
• Displace the cryo specimen arm to the rear
limit stop and lower end position.
• Release the clamping lever (1) on the micro-
tome base plate.
• Carefully pull the chamber forward towards
yourself until the cryo specimen arm (2) is out-
side the chamber.
• Retighten the clamping lever (1) on the micro-
tome base plate.
