Ding She Ru takes the world Guinness record for Chinese medicine what technique

Section slide specimen. For optical microscope or electron microscope observation of animal and plant tissue thin section. Due to different requirements, can be used blade for freehand sectioning, can also be embedded in paraffin wax or fire cotton wool gel block of tissue or frozen at low temperatures, sliced with a slicer.

Slices were cut into 5 to 10 micrometer slices for light microscopy. Ultrathin sections cut from epoxy resin or methacrylic acid-embedded tissue blocks are 20 to 50 nanometers thick and are designed for observation under an electron microscope. Sections for general teaching purposes such as root tips and stems are commonly referred to as paraffin sections.

Sections: are made on a slicing machine. The thickness of the slices depends on the need, usually around 5-7 microns (μm).
