Gravity: The most basic sterilization cycle. Steam displaces air in the chamber by gravity (i.e. without mechanical assistance) through a drain port. Glassware, unwrapped goods, waste, utensils, redbags. Pre-Vacuum and/or Post-Vacuum: Air is mechanically removed from the chamber and load through a series of vacuum and pressure pulses.

Gravity die casting is a metal casting process where molten metal is poured into a durable metal mold using gravity. Once the metal cools and solidifies, the mold is opened to retrieve the casting. In sand casting, compacted sand is placed around a wooden or metal pattern, and additional cores are inserted to create internal features.

The choice of the concentration process to be used in a mineral depends on the physical and chemical characteristics of the constituents to be separated. Gravity concentration can be defined as the process by which particles of different sizes, shapes, and densities are separated from each other by the force of gravity or the centrifugal force.

The gravity displacement autoclaves are primarily used to process laboratory media, water, pharmaceutical products, regulated medical waste, and nonporous articles whose surfaces have direct steam contact. For gravity displacement sterilizers the penetration time into porous items is prolonged because of incomplete air elimination.

A: Prevacuum sterilizers run vacuum (or pre-vacuum) cycles. Vacuum sterilization cycles remove air from the autoclave chamber and load mechanically through a series of vacuum and pressure pulses. This allows steam to penetrate porous areas of the load that couldn't otherwise be reached using gravity air displacement.
