What are the commonly used sterilization methods for medical devices?

1.Glutaraldehyde Glutaraldehyde is a high level disinfectant and sterilizer, and its aldehyde group can alkylate amino, sulfhydryl, and carboxyl groups, altering bacterial RNA, DAN, and protein synthesis, which leads to bacterial death.

2. o-Phthalaldehyde (OPA) OPA kills bacteria by cross-linking with amino acids and denaturing proteins. The difference is that OPA has better lipid solubility, easier to penetrate the cell membrane of mycobacteria containing more lipids, and enter the bacterial body to play a role, so the killing effect on mycobacteria is stronger than glutaraldehyde.

3. Hydrogen peroxide is a strong oxidizing agent, releasing hydroxide molecules (primordial oxygen) to oxidize the enzyme system of microorganisms.

4. IFS international food standard certification, EU EMAS testing and certification, ISO9001, ISO14001 environmental management system certification and so on. It is an efficient broad-spectrum food-grade bactericidal disinfectant. It has the characteristics of thorough sterilization, does not produce microbial resistance, does not have any toxic residue, and does not cause repeated pollution.
