T4275 Sterilisation type code

Code Name Description Used in Sweden
AUTOCLAVE Autoclave Autoclave (Steam) is a method of sterilisation that utilizes pressure and heat to achieve a sterile environment. X
BETA_RADIATION Beta radiation Beta particles are able to penetrate living matter to a certain extent (radiation intensity from a small source of radioactive material decreases as one over the distance squared) and can change the structure of struck molecules. X
CHLORINE_DIOXIDE Chlorine dioxide Gaseous chlorine dioxide systems for sterilization of healthcare products are not mutagenic or carcinogenic in humans. As the chlorine dioxide concentration increases, the time required to achieve sterilization becomes progressively shorter. X
DRY_HEAT Dry heat This method should be used only for materials that might be damaged by moist heat or that are impenetrable to moist heat (e.g., powders, petroleum products, sharp instruments). There are two types of dry-heat sterilizers: the static-air type and the forced-air type. X
ELECTRON_BEAM_IRRADIATION Electron beam irradiation A commercially successful technology for sterilizing a variety of disposable medical devices with a wide range of densities. The e-beam inactivates micro-organisms either by causing microbial death as a direct effect of the destruction of a vital molecule or by an indirect chemical reaction. This is the same mechanism as in gamma irradiation, and the dose required is the same. X
ETHANOL Ethanol A chemical sterilisation method that utilizes ethanol as the sterilisation method. X
ETO_ETHYLENE_OXIDE Eto ethylene oxide A gas that is commonly used to sterilize objects sensitive to temperatures greater than 60 °C such as plastics, optics and electrics. Ethylene oxide treatment is generally carried out between 30 °C and 60 °C with relative humidity above 30% and a gas concentration between 200 and 800 mg/L for at least three hours. Ethylene oxide penetrates well, moving through paper, cloth, and some plastic films and is highly effective. X
FORMALDEHYDE Formaldehyde A chemical sterilisation agent used to provide sterilisation. Items being sterilized are usually immersed in the formaldehyde for a pre determined time period. X
GAMMA_RADIATION Gamma radiation Gamma rays are very penetrating and are commonly used for sterilisation of disposable medical equipment, such as syringes, needles, cannulas and IV sets. Gamma radiation requires bulky shielding for the safety of the operators; they also require storage of a radioisotope (usually Cobalt- 60), which continuously emits gamma rays (it cannot be turned off, and therefore always presents a hazard in the area of the facility). X
GLUTARALDEHYDE Glutaraldehyde A colourless liquid with a pungent odour used to sterilize medical and dental equipment. It is also used for industrial water treatment and as a chemical preservative. Glutaraldehyde is an oily liquid at room temperature (density 1.06 g/mL), and miscible with water, alcohol, and benzene. X
HIGH_INTENSITY_OR_PULSE_LIGHT High intensity or pulse light Pulsed light is a non-thermal sterilization method that uses brief intense pulses or flashes of white light to kill micro-organisms. X
HIGH_LEVEL_DISINFECTANT High-level disinfectant A germicide that inactivates all microbial pathogens, except small numbers of bacterial endospores. X
HYDROGEN_PEROXIDE Hydrogen peroxide Another chemical sterilizing agent. It is relatively non-toxic once diluted to low concentrations (although a dangerous oxidizer at high concentrations), and leaves no residue. X
LIQUID_CHEMICAL Liquid chemical A sterilization process that uses liquid chemical as its sterilant to kill microorganisms. X
MICROWAVE_RADIATION Microwave radiation Microwaves are used in medicine for disinfection of soft contact lenses, dental instruments, dentures, milk, and urinary catheters for intermittent self-catheterization. However, microwaves must only be used with products that are compatible (e.g., do not melt). Microwaves are radio-frequency waves, which are usually used at a frequency of 2450 MHz. X
NITROGEN_DIOXIDE Nitrogen dioxide A sterilization process that uses nitrogen dioxide radicals that are formed from dinitrogen tetroxide dimers to kill microorganisms. X
OZONE Ozone Is a method often times used in industrial settings to sterilize water and air, as well as a disinfectant for surfaces. It has the benefit of being able to oxidize most organic matter. It is a toxic and unstable gas that must be produced on-site, so it is not practical to use in many settings. X
PERACETIC_ACID Peracetic acid A chemical in the organic peroxide family. It is a bright, colorless liquid with a characteristic acrid acetic acid type odor. It has a strong oxidizing potential, is highly corrosive, and can explode at temperatures exceeding 110 °C. X
PLASMA Plasma A method of sterilisation that utilizes hydrogen peroxide vapour to sterilize heat sensitive equipment. X
SOUND_WAVES Sound waves Sound waves of frequency >20,000 cycle/second kills bacteria and some viruses on exposing for one hour. High frequency sound waves disrupt cells. They are used to clean and disinfect instruments as well as to reduce microbial load. X
SUPERCRITICAL_CARBON_DIOXIDE Supercrtical carbon dioxide A sterilization process that uses supercritical carbon dioxide in combination with a small percentage of additive to kill microorganisms. X
UNSPECIFIED Unspecified Trade Item Manufacturer has not specified the sterilisation method(s) of the trade item. X
UV_LIGHT UV light Useful for sterilisation of surfaces and some transparent objects. Many objects that are transparent to visible light absorb UV. UV irradiation is routinely used to sterilize the interiors of biological safety cabinets between uses. X
