3.2 Instrument specifications
Basic instrument with sectioning motor, separate control panel, programmable retraction with ON/OFF
selection, unique ergonomically positioned electronical lateral coarse feed wheel with user selectable
turn directions, without specimen orientation or additional accessories. 100-240/50-60Hz.
• Fully-Motorized Rotary Microtome with low-maintenance and backlash-free precision micrometer
feed system with step motor.
• Horizontal feed and vertical stroke mechanisms are based on cross roller bearings.
• The HistoCore AUTOCUT is primarily designed for motorized sectioning, but is also suitable for
manual sectioning applications.
• Smooth-running hand-wheel allows two manual sectioning modes: rocking mode and conventional
manual sectioning with full hand-wheel rotation, and 3 motorized sectioning modes: single,
continuous and step.
• The sectioning speed can be adjusted while motorized sectioning is in progress.
• The ergonomic handle of the safety handwheel can be centered while working motorized.
• The emergency stop button on the microtome front or E-stop function in optional foot stop will
interrupt motorized sectioning immediately in case of emergency.
• Two independent hand-wheel locking systems, plus one electronic brake after motorized usage,
ensure that the hand-wheel is safely locked.
• Unique operator-adjustable force balancing system with spring force compensation offers two
advantages:
1. Flexibility to adapt the spring force to different weights of specimen/clamps, eliminating the
risk of an object head dropping into the knife.
2. No need for a heavy counter balance in the hand-wheel.
• All important controls are located on the user friendly separate control panel with adjustable
inclination angle for ergonomic operation.

• Section thickness settings for trimming and sectioning can be selected and saved independently of
each other.
• Individually adjustable sectioning range on the specimen size (sectioning window).
• Important operating information is indicated on the front of the instrument:
1. trimming or section thickness,
2. specimen retraction (Retract),
3. emergency stop (E-stop),
4. hand-wheel/specimen head locking function (Lock),
5. section counter and section thickness totalizer with reset function.
• Programmable specimen retraction system for manual cutting mode with ON/OFF function
• Self-adjusting specimen retraction in motorized sectioning mode, speed dependent.
• Unique rocking mode function on the control panel for rapid trimming. Allows turning the hand-wheel
back and forth over a short distance without the need of deactivating the retraction. Each change in
the sense of rotation will be electronically detected and automatically converted into an advance or
retraction movement of the specimen, without compromising the ribboning of the sections.
• Motorized horizontal specimen head movement can be done in 2 ways:
1. Using the coarse feed buttons on the control panel in two speeds per direction in continuous
or in step feeding mode.
2. Using the ergonomically positioned and unique coarse feed wheel which can be personalized
by user selectable preferred turn direction.
• Visual/acoustic signals indicate the remaining feed and the front and rear travel limits.
• Efficient and rapid specimen exchange
1. by using the user programmable Memo position
2. the fast homing function of the object head within 13 +/- 2 seconds from front to rear position.
• Large top surface area allows placement of objects that require a flat surface.
• Optional removable top tray allows storage of sectioning tools and prevents items from falling.
