Introducing our NEW rotary microtomes!

We at Precisionary Instruments have been making tissue slicers for over 15 years. Now, we would like to launch a brand new product line: ROTARY MICROTOMES!

What are rotary microtomes?

A microtome makes tissue sections by making cuts that move vertically downward against a knife. A “rotary” microtome uses a rotational handwheel to control the cutting movement (see Figure 1). One rotation of the operating wheel produces a complete cycle of cutting (both downward and upward strokes). A rotary microtome can be used to cut ultrathin sections, often paraffin-wax embedded sections for pathology and histology studies.

How Rotary Microtomes work
Figure 1. How rotary microtomes work. Your sample is typically embedded in a specimen block, which is then held in the specimen holder. As the specimen block travels vertically in an up-and-down motion, thin slices are cut over a knife. These thin sections can then be plated on a glass slide.

Our new models

We offer three (3) brand new models:

Key features of our new rotary microtome models

  • Heavy and stable unit core, idea for serial sections in large numbers.
  • RF-600 manual model comes with 2 specimen clamp holders, one for universal cassettes and one for large paraffin blocks.
  • RF-800 and RF-1000 models come with LCD touchscreen control panels
  • RF-1000 had fully automated cutting abilities that are controllable through the touchscreen, the side control panel, and the foot pedal.
