Cassette Hydrogen Peroxide Sterilizer system is hydrogen peroxide (H₂O₂), in low temperature environment through the electromagnetic field of hydrogen peroxide (H₂O₂) to form hydrogen peroxide (H₂O₂) plasma, combined with hydrogen peroxide (H₂O₂) gas and hydrogen peroxide (H₂O₂) plasma for indoor items at low temperature, dry sterilization, and can effectively dissociate residual hydrogen peroxide (H₂O₂).
In operating rooms, the STL‑PW model delivers virtually immediate access to sterile tools. It’s easy to install and operate, requiring only single-phase power and hydrogen peroxide cassettes for a cassette plasma sterilizer system. This eliminates the need to send instruments to a central CSSD, thereby reducing the risk of damage or contamination during transport.
