Leica Rotary Microtome

The fully automated Leica RM2255 microtome embodies the latest technological innovations in microtomy and perfectly harmonizes practical features with an ergonomic design and user safety. Its two-in-one design concept, which allows motorized as well as manual sectioning, provides reproducible, quality sections.
Features:

Compact, ergonomic design
Ergonomically designed handwheel handle
Smooth-running handwheel with integrated quick-lock mechanism for safety
Enclosed micrometer feed mechanism
Low-maintenance cross-roller bearings
Two forward and backward coarse feed speeds
Alternate trimming and sectioning modes, as indicated on the display
Speed control through the cutting window for enhanced efficiency
Automatic, variable specimen retraction, depending on sectioning speed
Section thickness totalizer and section counter
Intuitive control panel
Integrated communication display
Precise specimen orientation with zero point reference
Knife holder design with red colored knife guard
Precise lateral knife holder adjustment with click stop settings
Spacious and easy-to-clean section waste tray
Wide range of accessories
