Warning
Never work with only one clamping jaw, as this does not ensure the stability required for the sectioning
process. Also, a long knife will not be sufficiently protected by the safety guard in this instance.
3. Lift off the clamping jaw
on the right side (caution: do not lose the washers!)
and feed it into the adjacent hole
. Tighten the screws from the underside of the
segment arc. Repeat on the left side.
Now use the longer knife backrest provided.

7.4.7 Cleaning the blade and knife holders
Note
•
For daily cleaning, just remove the section waste from the blade/knife holder using a dry brush.
Please use a cold brush, as otherwise the section waste will thaw and stick to the blade or knife
holder.
•
Mechanical damage to the pressure plate will strongly affect the sectioning quality. For this reason
it is important to ensure that the clamping area is not damaged during cleaning or other work.
•
For disinfection purposes, standard commercial detergents and disinfectants can be used at room
temperature outside of the cryostat chamber.
•
Wear gloves during cleaning to prevent freezer burn.
