Methods of Sterilization

Filtration Sterilization: Types, Mechanism, Uses

Filtration Sterilization: Types, Mechanism, Uses

Filtration is the preferred method of sterilizing heat sensitive liquid and gases without exposure to denaturing heat.

Radiation Sterilization: Types, Mechanism, Applications

Radiation Sterilization: Types, Mechanism, Applications

Sterilization and decontamination in the medical supplies (surgical supplies, vaccines, and drugs) is done using radiation sterilization.

Disinfection: Methods and Uses

Disinfection: Methods and Uses

Disinfection is a process whereby pathogenic organisms, but not necessarily all microorganisms or spores, are destroyed.

Autoclave: Principle, Procedure, Types, Uses

Autoclave: Principle, Procedure, Types, Uses

Autoclave kills microorganisms using saturated stem under pressure. Autoclave comprises of three parts: a pressure chamber, a lid and an electrical heater.

Ethylene Oxide (ETO) Sterilization: Features and Limitations

Ethylene Oxide (ETO) Sterilization: Features and Limitations

ETO is an effective sterilizing agent for heat and moisture-sensitive materials in hospitals, industries, and laboratories.

Moist Heat Sterilization: Principle, Advantages, Disadvantages

Moist Heat Sterilization: Principle, Advantages, Disadvantages

Moist heat has better penetrating power than dry heat and at a given temperature, produces a faster reduction in the number of living organisms.

Dry-Heat Sterilization: Principle, Advantages, Disadvantages

Dry-Heat Sterilization: Principle, Advantages, Disadvantages

Dry heat ovens are used to sterilize items that might be damaged by moist heat or that are impenetrable to moist heat.
