What are the different methods of sterilization?

Sterilization can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.

What are the 3 types of sterilization?

Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.

  • Plasma Gas Sterilizers.
  • Autoclaves.
  • Vaporized Hydrogen Peroxide Sterilizers.

What is the most widely used method of sterilization?

Of all the methods available for sterilization, moist heat in the form of saturated steam under pressure is the most widely used and the most dependable. Steam sterilization is nontoxic, inexpensive 826, rapidly microbicidal, sporicidal, and rapidly heats and penetrates fabrics (Table 6) 827.

What is the most common method of sterilization?

Autoclaving
Autoclaving is probably the most common, quick, and safe sterilization method. Another thermal processing method is dry heat sterilization. In dry environments, bacterial spores can withstand higher temperatures for longer.

What are the two types of heat used for sterilization?

When a substance is exposed to the direct flame for a long time, the microbe molecules shrink and die. The two types of heat methods are dry heat methods and moist heat methods.

Which is the best method for sterilization of milk?

STERILIZATION BY MOIST HEAT. Methods of application of moist heat include: 1- Pasteurization: This method is used for sterilization of milk. Temperature required is either 63ºC – 66ºC for 30 minutes or 72ºC for 20 second by this method eating utensils, clothes and bed sheets of patient can also be sterilized.

How is the design of a continuous sterilization cycle approached?

The design of continuous sterilization cycles may be approached in exactly the same way as for batch sterilization systems.

Which is the best physical indicator for radiation sterilization?

Physical Indicator: In radiation sterilization a plastic or perspex dosimeterwhich gradually darkens in proportion to the radiation it absorbs give an accuratemeasure of the radiation dose and is considered to be the best technique currentlyavailable for the radiation sterilization process.
