Cleaning
• Remove frozen section waste from the cryostat with a cold brush every day.
• Remove the section waste tray for emptying.
• Remove the storage shelves and the brush shelf for cleaning.
• Remove the closed sliding window from the front by gently lifting it (see 9.3.3, "Replacing the
fluorescent lamp").
The use of flammable sprays within the cryostat chamber is permitted only with the Leica
Cryofect tested by us.
Do not use organic solvents or any other aggressive substances for cleaning and disin-
fecting!
Wear safety gloves at all times when cleaning, to prevent contact with contaminated
substances!
Use only disinfectants listed in these Instructions for Use, such as Leica Cryofect (alco-
hol or other common alcohol-based disinfectants).

• After the exposure time is up, wipe out clean-
ing fluid from the cryochamber with a suitable
soft cloth.
• If the cryostat is completely defrosted, the
plug on the floor of the cryochamber must be
removed. Afterward, reinsert and check that
they are securely in place.
• The defrosting fluid is drained to a separate
catch bin alongside the instrument through a
drain tube.
The catch tank (1) collects the con-
densate that accumulates during de-
frosting. Therefore, check the level
regularly and empty the container ac-
cording to applicable laboratory regu-
1
lations.
