EOG sterilization refers to the ethylene oxide gas (EOG), a toxic gas, which is  infused into the package to kill bacterial. The gas is infused over a period of hours to days, depending on how long it takes in a given package to kill the necessary bacteria. The packages for EOG Sterilization is generally a plastic side that conforms to the shape of the item being sterilized attached to a paper-like backing that is permeable to the gas. The paper-like backing allows only very small molecules, such as ethylene oxide gas, and the components of air, to pass through. High pressure pushes the gas through the backing displacing all the air, the ethylene oxide has is allowed to cycle around the components, followed by the toxic gas getting flushed out with air. The backing of the EOG sterilized products are where the item name, lot number and other necessary information, including expiration date, is listed. Many items in dentist and doctors' offices are sterilized with EOG sterilization.

Ethylene Oxide Gas sterilization companies use what's referred to as the overkill method. This is designed to kill one million spores of what's referred to as the most resistant organism, something called bacillus astrophase, in half of the normal cycle time.

The second type of sterilization used with electrolysis probes is referred to as x-ray or gamma radiation. The packaging looks different than for EOG sterilization, especially has the sterilization is marked via a color changing dot. This dot is prominently placed on the packaging and the color change for after exposure to radiation is clearly defined.  and that's usually in a package like this this kind of a package. It generally has a dot and that dot tells you if the product has been sterilized. This type of all paper packaging can be seen in Doctor and Dentists' offices as well. The sterilzation company, using gamma or X-ray radiation, determine the amount of radiation, also referred to as the dosage, that's necessary for the overkill method. Note that after the irradiation complete, the dot on the packaging should have changed color, usually from blue to red.
