Leica RM2125 Microtome

The Leica RM2125 Microtome is a manual microtome that can provide sectioning thickness of 0.5-60μm and trimming thickness of 10 or 50μm

Leica RM2155 Microtome

The Leica RM2155 is a reliable rotary microtome designed for fully motorized sectioning of both paraffin and resin-embedded specimens. Offering a broad application spectrum in histology laboratories, the RM2155 also has applications in industrial materials and quality control. The Leica microtome’s two-in-one design concept allows motorized as well as manual sectioning, and provides reproducible quality sections.

The RM2155 sectioning speed can be adjusted to cut hard materials as well as paraffin-embedded specimens at high throughput without affecting sectioning quality. This microtome is designed for users who require a fully motorized/electronic microtome for their laboratory needs, making it an ideal instrument for fundamental sectioning of standard and non-standard materials.

The fully motorized Leica RM2155 microtome can cut sections from 0.5 to 60 microns with an automatic motorized coarse feed as well as an adjustable hand wheel for speed control and selectable cutting modes. The knife holder comes with new clamping plates, ensuring the user accurate, non-erratic sectioning.
