Introducing our NEW rotary microtomes!

Published on February 6, 2023

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.

“Our goal is to develop and apply new ultrafast laser scanning multimodal imaging and spectroscopic technologies, such as stimulated Raman scattering (SRS), second harmonic generation (SHG), and multiphoton fluorescence (MPF) microscopy, for visualizing molecular composition and metabolic dynamics in situ at subcellular resolution to study aging and diseases,” explains Professor Lingyan Shi. The Laboratory of Optical Bioimaging and Spectroscopy, led by Dr. Shi, is at the forefront of this groundbreaking research.
