71 Leica CM1950 – Cryostat
12. Maintenance and Cleaning
12.1 General maintenance instructions
The microtome is virtually maintenance-free. To ensure a smooth operation
of the instrument over several years we recommend the following:
• At least once a year, have the instrument inspected by a qualified ser-
vice engineer authorized by Leica.
• Enter into a service contract at the end of the warranty period. For more
information, please contact your local Leica technical service center.
• Clean the instrument daily.
Do not use organic solvents or any other aggressive substances for
cleaning and disinfecting!
Use only disinfectants listed in these Instructions for Use, such as
Leica Cryofect (alcohol or other common alcohol-based disinfec-
tants).
• Drain the cleaning liquid through the hose after the recommended expo-
sure time is over and collect it in the waste container (1).
If completely defrosted, bacteria filters and filter bags MUST be
removed, as melted coverslip mountant clogs the extraction line.
The bacteria filter absorbs the moisture during defrosting and thus
becomes unusable!
• Every day, remove frozen section waste from the cryostat using a cold
brush or use the (optional) extraction device.
• 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 page. 75 "Replacing the fluorescent lamp" ).
