Regarding the sterilization technology of vaporized hydrogen peroxide

Hefei Teling Biotechnology Co., Ltd. - Dry VHP technology uses a vaporized hydrogen peroxide generator to completely vaporize a hydrogen peroxide solution with a concentration of 35%, and then uses pipeline transportation or direct spraying to perform biological decontamination in enclosed spaces. Hydrogen peroxide generates free hydroxyl groups during vaporization, causing oxidative damage to cellular components such as lipids, proteins, and DNA. Gaseous hydrogen peroxide has the ability to kill various microorganisms such as bacteria, fungi, and viruses at room temperature. Suitable for sterilization of air and object surfaces under dry, low temperature (room temperature), normal pressure/vacuum/positive pressure conditions.

Working principle diagram of vaporized hydrogen peroxide

The characteristic of dry VHP technology is that the hydrogen peroxide gas in the room and chamber is always maintained below the "condensation point" for biological decontamination. Under the expected concentration of hydrogen peroxide gas, always control the relative humidity of the biologically contaminated space during the circulation process to prevent humidity saturation in the environment, thereby reducing the impact of hydrogen peroxide condensate formation. The advantage of dry sterilization is that it can achieve the expected uniform biological decontamination effect while reducing its impact on materials and optimizing the residual time of hydrogen peroxide gas.

Sterilization effect of vaporized hydrogen peroxide sterilizer on ambulance
Experimental observation of the disinfection effect of the Meizhuo biological vaporization hydrogen peroxide sterilizer TL-V100 on the air and object surfaces inside ambulances. The method shall be carried out in accordance with the "Disinfection Technical Specification". Result: Bacterial colony counting was performed on the ground, stretcher, and seats inside the ambulance, and a killing rate of more than 5 logarithms was achieved for thermophilic Bacillus subtilis; The vaporized hydrogen peroxide sterilizer can also achieve a killing rate of more than 5 logarithms against Bacillus subtilis. The concentration of hydrogen peroxide after residue removal is below 1ppm. Conclusion: The vaporized hydrogen peroxide sterilizer meets the sterilization requirements, has a short sterilization cycle, and is environmentally friendly and safe.
