最常用的醫用採樣拭子滅菌方法

Sterilization is an incredibly important part of any medical process. Here at Medico, all of our sterile products undergo either ethylene oxide gas sterilization or gamma irradiation sterilization before they are sent to our customers, which ensures the swabs are free from human DNA, enzymes that degrade DNA and RNA, and polymerase chain reaction inhibitors.

How are Medical Sampling Swabs Sterilized?

The following are the three most common methods of medical sampling swab sterilization:

• Ethylene oxide (環氧乙烷或環氧乙烷) – EtO 是一種利用 99-145°F 之間介質溫度的滅菌方法 (37–63°C), 在細菌或病毒中產生蛋白質和 DNA 的化學反應. 該過程的最後一步是加熱空氣循環，溫度通常在 122-140°F 之間 (50-60℃) 從產品和包裝中去除 EO 氣體.
• Autoclaves – Autoclave sterilization uses steam and pressure to increase the temperature between 250-270°F (121-132℃) 殺死細菌和病毒.
• Gamma irradiation – Gamma irradiation sterilization uses a radioactive material that emits high energy gamma rays, 分解細菌或病毒中的 DNA.
