PVHP Pico-sized Vaporized Hydrogen Peroxide
The vapor from the hydrogen peroxide vapor sterilizer consists of particles in the picometer range, with 1 picometer being one trillionth (10-12) of a meter. In contrast, the particle size of spray-type sterilizers is typically in the micrometer range, whereas the hydrogen peroxide vapor used by GME Bio has particles that are about one ten millionth (1/10,000,000) of that size.
Conventional aerosol-type sterilization methods, with larger particle sizes, are significantly affected by gravity, making it difficult to achieve precise sterilization results based on the nozzle's diffusion direction and height. On the other hand, the hydrogen peroxide vapor sterilization method, with its much smaller particle size, consistently delivers the same sterilization results due to superior diffusion capabilities.
For example, aerosol-type sterilization methods typically use low-concentration hydrogen peroxide (6~10%), whereas vapor particle sterilization methods use high-concentration hydrogen peroxide (30~35%). The hydrogen peroxide concentration used for sterilization is usually maintained between 150 and 500 ppm, ensuring safety without significant risks associated with hydrogen peroxide.
However, when it comes to oxidizing power, there are risks when hydrogen peroxide is in liquid form. Using aerosol-type sterilization methods can lead to higher oxidizing power, posing a risk of damage to panels or epoxy. In contrast, utilizing the hydrogen peroxide vapor sterilization method ensures consistent sterilization values, providing higher diffusion capability and superior stability compared to other types.
