2. Safety and Design
• When disinfecting the instrument, take appropriate protective measures (gloves, mask,
protective clothing, etc.).
• When using detergents and disinfectants please comply with the safety precautions of the
disinfectant manufacturer!
• The integrated glass anti-roll guide of the blade holders CE, CN and CN-Z can be cleaned
either with acetone or alcohol.
• Dispose of waste liquid according to the waste disposal regulations!
• Do not use external heaters for drying the cryochamber. This can cause damage to the cool-
ing system!
• Do not turn the instrument on before the cryochamber is completely dry! Frost formation!
• All components removed from the cryostat must be carefully dried before returning them to
the cryochamber!
• The front panel and the slit cover of the microtome must be completely dry before turning
on the instrument!
2.7 Cleaning, disinfection – Turning the instrument back on
It is not necessary to remove the microtome for disinfection.
Remove section waste after EVERY sectioning operation and BEFORE changing speci-
mens. Remove the section waste using a paper towel soaked in Cryofect (or an alcohol-
based disinfectant) or by means of an extraction nozzle (optional). Do not start the disin-
fection before swiveling the anti-roll plate to the side! Each new specimen is a potential
source of contamination.
• The instrument has been designed for UV disinfection! Spray disinfection with Leica Cryofect
is also possible, thanks to the special insulation of the microtome. (Cryofect is not available
in all countries!)
