Product type
Gamma sterilization is a method used to eliminate harmful microorganisms from medical devices and lab equipment through the use of gamma radiation. This process involves exposing products to gamma rays emitted from a radioactive source, which penetrates the items and disrupts the DNA of bacteria, viruses, and fungi, rendering them inactive. Gamma sterilization is effective for a wide variety of materials, including plastics, metals, and glass, making it suitable for diverse medical applications.
| Radiation source | Cobalt-60 or Cesium-137 |
| Dose range | 10 kGy to 50 kGy |
| Sterilization time | Typically 24 to 72 hours |
| Temperature range | Room temperature to 60°C |
| Packaging types | Single-use pouches, bulk containers, and trays |
When selecting gamma sterilization services, buyers should consider the specific materials and products that need to be sterilized, as well as the required sterility assurance level (SAL). It is important to specify the desired radiation dose, packaging requirements, and any relevant certifications, such as ISO standards. Additionally, understanding the turnaround time and capacity for large quantities can help in making an informed decision.
