Diffusion pump

A diffusion pump is a device used to create a very high vacuum environment by removing air and gases from a chamber. It works by heating a special oil and forcing it to vaporize, then allowing the vapor to flow downward through intricate pathways. As the vapor moves, it captures gas molecules from the chamber and carries them away to a cold trap where they condense, effectively pumping out air. Diffusion pumps are essential in applications like scientific research and manufacturing, providing ultra-clean, low-pressure conditions needed for precise experiments and processes.
