Koch's or Arnold's steam sterilizer: used for steam sterilization A pressure cooker: used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter:
A vacuum pump sucks air or air/steam mixtures from the chamber. Superatmospheric cycles: Achieved with a vacuum pump. It starts with a vacuum followed by a steam pulse followed by a vacuum followed by a steam pulse. The number of pulses depends on the particular autoclave and cycle chosen. Subatmospheric cycles:
This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave, sometimes called a converter or steam sterilizer. The object or liquid is placed in the autoclave chamber, which is then sealed and heated using pressurized steam to a temperature set point for a defined period of time.
The presence of moisture, such as in steam sterilization, significantly speeds up heat penetration. There are two types of hot air convection (Convection refers to the circulation of heated air within the chamber of the oven) sterilizers: Gravity convection; Mechanical convection
Soil steam sterilization, a farming technique that sterilizes soil with steam in open fields or greenhouses; Sterilization (medicine) renders a human unable to reproduce; Neutering is the surgical sterilization of animals; Irradiation induced sterility is used in the sterile insect technique; A chemosterilant is a chemical compound that causes ...
Moist heat causes destruction of micro-organisms by denaturation of macromolecules, primarily proteins. Destruction of cells by lysis may also play a role. While "sterility" implies the destruction of free-living organisms which may grow within a sample, sterilization does not necessarily entail destruction of infectious matter.
Soil steam sterilization (soil steaming) is a farming technique that sterilizes soil with steam in open fields or greenhouses. Pests of plant cultures such as weeds, bacteria, fungi and viruses are killed through induced hot steam which causes vital cellular proteins to unfold .
Pigeon keeping or pigeon fancying is the art and science of breeding domestic pigeons. People have practiced pigeon keeping for at least 5,000 years [ 1 ] and in almost every part of the world. In that time, humans have substantially altered the morphology and the behaviour of the domesticated descendants of the rock dove to suit their needs ...
