The working principle and application field of a fully automatic biological tissue embedding machine

The full name of the embedding machine is the fully automatic biological tissue embedding machine, which is currently widely used in conventional histological slicing techniques. When making slices or ultra-thin slices, it is difficult to make slices with uniform thickness due to the soft or uneven local hardness of the tissue. So it is necessary to soak the inside of the tissue with a certain substance, and the entire tissue will harden. First, melt paraffin wax into the embedding bracket (mold), and then use tweezers to remove the tissue block that has been soaked in wax from the dehydration box. Place it in the center of the embedding bracket and place it on a small cold table. Use tweezers to gently press the tissue block to achieve flatness. Cover the bottom of the dehydration box, add paraffin wax, and move it to the freezing table. After freezing, remove the tissue wax block for cutting.

The embedding machine is not only used to observe the morphology and structure of normal cell tissues, but also as the main method for studying, observing, and judging the morphological changes of cell tissues in disciplines such as pathology and forensic medicine. It has also been widely used in research in many other disciplines; In teaching, to achieve the observation of sliced specimens under light microscopy. Because the embedding machine can be set with automatic startup and shutdown programs, and is equipped with washable tweezers heating holes, shadowless lighting, large capacity wax melting cylinders, and also has memory function, and fast cooling.

The embedding machine can be divided into independent models and integrated machine models (split design). Integrated machine models (split design): The entire machine is composed of various frozen parts of the embedding part, which is a split design of the embedding and cooling parts. The two parts can be separated or combined left and right; Fast heating, accurate temperature control, and reliable operation; Its independent cooling countertop.
