PART 5 MAINTENANCE AND CARE
5-1 CLEANING AND CARE
Cleaning and care of the microtome should be
carried out daily. Please proceed as follows:
• Lock the hand wheel.
• Remove the knife from the knife carrier. Clean
it and store it in a knife case!
• Remove section waste by using a
dry brush.
• Pull the section waste tray towards
the front and dispose of the section waste
according to your specific lab regulations.
Caution:
Never put the knife with the cutting
edge upward on the table!!
• Loosen the clamping lever on the left side of
the knife carrier and pull the knife carrier
towards the front.
• Clean the operating controls and the surfaces
of the knife carrier, especially the space where
the knife carrier is installed.
• Clean the consoles, hand wheel, coarse feed
wheel, specimen clamping system, specimen
orientation as well as the base plate and
housing.
Note:
Mild domestic cleaners can be used to
clean the microtome. Do not use
aggressive cleaners or solvents, as the paint and
plastic parts can be affected.
Warning:
When getting in contact with cleaning
agents or paraffin repellents, e.g. Para
Gard, the surface of the cover ribbon behind the
specimen clamping might be affected. For this
reason, please note that the cover ribbon does not
get in contact with these agents when cleaning
the housing, knife carrier or the base plate.
• Before starting sectioning, instrument, knife
carrier and section waste tray should be
treated with a commercially available paraffin
repellent.
Note:
This medium considerably reduces the adhesive
force of paraffin waste on the individual parts of
the microtome.
