The Leica VT1200S is a fully automatic microtome with a 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 be-
fore each cut. There is no automatic specimen retraction in this mode; however, retraction can be per-
formed 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 speci-
men surface and the blade from coming into contact while the blade is being retracted.
