Operating Manual V1.1 – 05/2007
A few rules:
Always begin at a low extraction level, then slowly increase it.
Do not use high extraction levels unless absolutely necessary.
Different specimen sizes require different extraction levels.
The faster the trimming or sectioning speed, the lower the extraction
level should be.
The larger and/or thicker the specimen to be trimmed, the lower the
extraction value.
When section specimens with a diameter of 0.5 cm, the anti-roll guide
stretches the section adequately. For larger specimens, we recommend
using the vacuum function.

The values listed here are possible
settings that depend on the tissue
type, specimen size, section thick-
ness and section speed, and are in-
tended for orientation purposes only.
These settings can also vary when using
different anti-roll plate!
