The Leica VT1200 S is a fully automatic microtome with vibrating blade. It can be operated in automatic as well as
semiautomatic sectioning mode.
In semiautomatic sectioning mode, a manual feed to the desired section thickness must be carried out before
each cut. There is no automatic specimen retraction in this mode; however, retraction can be performed manually.
In automatic mode, an automatic feed (AUTO FEED) to the selected section thickness is carried out before each
cut, and the specimen is lowered to the desired retraction value after each cut to prevent the specimen surface
and the blade from coming into contact while the blade is being retracted.
