    Summary
    This summary is machine-generated.

    A new surfometer technique accurately measures section thickness. Microtome settings are unreliable for quenched or wax-embedded tissues but accurate for araldite sections.

    Area of Science:

    • Materials Science
    • Histology
    • Biotechnology

    Background:

    • Accurate measurement of section thickness is crucial for reproducible scientific results in histology and materials science.
    • Traditional reliance on microtome settings for section thickness monitoring can be inaccurate, particularly for certain sample types.

    Purpose of the Study:

    • To describe a rapid, simple, accurate, and reproducible method for measuring section thickness.
    • To evaluate the reliability of microtome settings for monitoring section thickness across different embedding media.

    Main Methods:

    • Utilized a surfometer, a specialized instrument, for precise section thickness measurements.
    • Compared surfometer measurements with microtome settings for quenched, wax-embedded, dewaxed, and araldite-embedded tissue sections.

    Main Results:

    • The surfometer provides a reliable method for measuring section thickness.
    • Microtome settings are not dependable for monitoring the thickness of quenched or wax-embedded tissue sections.
    • A linear correlation was observed between microtome settings and the thickness of dewaxed sections.
    • Microtome settings accurately reflect the thickness of araldite sections.

    Conclusions:

    • The surfometer is a valuable tool for accurate section thickness determination.
    • Researchers should exercise caution when using microtome settings alone to control section thickness, especially for specific sample preparations.
    • Microtome settings are reliable indicators for araldite-embedded sections, offering a practical advantage in specific research contexts.
