Several pieces of equipment in histology laboratories utilize vacuum:
1. Tissue Processors: These use a vacuum to facilitate the infiltration of fixatives, dehydrating agents, and embedding media. 2. Vacuum Embedding Stations: Specialized stations that use vacuum to embed tissues in paraffin or resin. 3. Ultramicrotomes: For sectioning ultra-thin slices of tissue, a vacuum helps in stabilizing the knife and specimen. 4. Scanning Electron Microscopes (SEM): High vacuum conditions are essential for the operation of SEM, ensuring electron beam stability and image clarity.
