Terminal Sterilization Services Market Segmentation

By Sterilization Method

• Ethylene Oxide (EtO)

Ethylene Oxide is the choice for sterilizing medical devices. This is because Ethylene Oxide can handle devices that're sensitive to heat and moisture. It can also sterilize devices with shapes and packaged products. Ethylene Oxide is really good at getting into spaces and it is allowed by regulations. That is why Ethylene Oxide is the method for sterilizing large quantities of medical devices. Even though it can be hard to comply with rules Ethylene Oxide is still the best option, for large-scale sterilization of medical devices.

• Gamma Radiation

Gamma Radiation is often used for things that we throw away because it can go really deep and it is reliable. Gamma Radiation helps us treat a lot of things at the time and makes sure they are completely clean which is great, for medical products that are made to be cleaned with Gamma Radiation and can handle it.

• Electron Beam (E-beam)

People are starting to use Electron Beam sterilization more. This is because Electron Beam sterilization is really fast and it does not leave much stuff behind as EtO does. Electron Beam sterilization is good for things that're not too thick. It also lets us sterilize things when we need to which means we can get them back in use a lot quicker. Electron Beam sterilization is really helpful, for this reason.

• Steam

Steam sterilization is mostly used for heat- and moisture-resistant products, providing cost-effectiveness and validated protocols. The use of steam sterilization is still limited to compatible materials but remains effective for pharmaceutical and certain device sterilizations.
