The segment arc and universal specimen holder are highly suitable for
the clamping of small specimens embedded in plastic.
• The specimen is inserted in the holder [a] and clamped with the
screw [b] with the hex head wrench [c].
• Then the holder together with the specimen is put into the segment
carrier [e], where the holder can be turned 360°.
• Thus, the specimen can be aligned as required.
• Then, the holder is clamped into the selected position with the
screw [d].
• The carrier [e] can be moved on the base [f]. This way, the surface
of the specimen can be placed parallel to the knife/blade.
• The screw [g] is used to swing the carrier onto the base.

INJURIES
Due to moving parts on the knife/blade holder and the extrem sharp-
ness of the microtome knife or blade, a danger area arises, which
might lead to hand injuries if the safety features and the instruction
manual are not followed carefully. The knife or blade carriers are
equipped with a knife guard for user safety while adjusting knife or
blade and specimen.
