Pure ethylene oxide gas
S broad-spectrum biocidal activity
Generation of steam under pressure
Porous loads (i.e. dressings) are of the types of ‘portable’ sterilizers
large-scale sterilizers generally have internal electric heaters
Bottled fluid sterilizers employing a minimum temperature of 121°C.
‘portable’ sterilizers, for routine hospital or industrial use
Shelves within the chamber are perforated to prevent cool spots developing inside the chamber.
A fixed temperature sensor connected to a chart recorder provides a permanent record of the sterilization cycle.
Appropriate door-locking controls should be incorporated to shorten the heating-up stage
A fan is fitted to the rear of the oven to prevent interruption of a sterilization cycle once begun
Pure ethylene oxide gas can be used below atmospheric pressure in sterilizer chambers from which all air has been removed
Formaldehyde limits the packaging materials that can be employed to principally paper and cotton fabric.
Formaldehyde cannot normally be detected by smell at concentrations lower than those permitted in the atmosphere
Ethylene chlorohydrin are potentially mutagenic and carcinogenic
Radiation sterilization is generally applied to articles in the aqueous state
Radiation sterilization has not proved to be a method of industrial sterilization of heat-sensitive products.
In the case of UV light , mould spores prove to be most resistant
Electron or gamma-irradiation is not as efficient a sterilization method as UV irradiation
Trapping within the matrix of the filter material is one of the mechanisms of filtration
The principal application of sterilizinggrade filters related to the venting systems on fermenters
Filtration sterilization cannot be used for the clarification and sterilization of liquids and gases.
UV light used in the sterilization of the treatment of manufacturing-grade water.
