Cleaning the knife holder CN
Daily cleaning
For daily cleaning, it is enough to fold the anti-roll
guide system forwards and remove the section
waste from the knife holder using a dry brush.
Please use a cold brush, as otherwise the sec-
tion waste will thaw and stick to the knife holder.

For disinfection, commercially avail-
able, mild cleaners and disinfectants
can be used – we recommend Leica
Cryofect.
It is not necessary to oil the parts, such
as the T-piece on the microtome base
plate, clamping lever etc.
The safety gloves included in the stan-
dard scope of delivery must be worn
when cleaning the blade holder to
prevent frostbite of the skin.
