HISTOLOGY & PATHOLOGY

Histopathology is the study of disease by using a microscope to examine tissues or surgical biopsies that are processed, fixed, sectioned, and plated onto glass slides. Tissue slices are then processed by staining, where different dyes and antibodies help visualize specific components of tissues and proteins. Hematoxylin-Eosin (H&E) staining has been used in pathology for over a century.
Because histopathology requires extremely fine and thin tissue sections (often down to 5µm or thinner), obtaining consistent sections is crucial for further processing. The process of cutting tissue slices also needs to occur rapidly because serial sections are needed. Therefore, histology and pathology require a rotary microtome that can quickly make high quality thin tissue slices without friction, chattermarks, or inconsistencies.
COMMON PROBLEMS WITH TISSUE SLICES FOR HISTOPATHOLOGY

Tissue specimens for histopathology are typically fixed and embedded in paraffin wax for slicing. This preservation and embedding method allows for long-term storage of tissue samples. However, paraffin wax and other resins are extremely hard, so they require a type of microtome that can adequately cut through hard materials. Furthermore, pathology sections for histology need to be very thin, so a microtome needs to be able to cut tissue slices down to just a few microns–and consistently too! Microtomes also need to be stable so that no chattermarks appear on the surface of tissue slices.
MAKING BETTER TISSUE SLICES FOR HISTOPATHOLOGY
PRECISIONARY ROTARY MICROTOMES
Rotary microtomes are routinely used for making paraffin-wax embedded tissue sections for histology and pathology. Because they are used for high volume sectioning, rotary microtomes need to be robust.
Precisionary Instruments offers a full line of high quality rotary microtomes for histopathology, research, and clinical purposes. Our microtomes give you reliable sections over a range of tissue slice thicknesses.
