Ethylene oxide sterilizer is mainly through its non-specific alkylation with genetic materials such as protein and DNA / RNA in microorganisms, resulting in the denaturation of proteins and genetic materials, and finally the death of microorganisms due to blocked metabolism.
Humidification: Utilizes steam degradation analysis method with built-in steam generator for comprehensive and uniform humidification and heating while minimizing water mist.
3.5" LCD screen: Equipped with a filter for stability, prolonging the service life and accuracy of the control screen.
Power-off memory function: Preserves sterilization data and automatically resumes unfinished work procedures in case of accidents or power loss.
Safety protection function: Includes alarm protection for abnormal temperature, ultra-high temperature, abnormal pressure, low vacuum rate, residual faults, phase sequence errors, and power shortage in the sterilization chamber to prevent further issues.
Ethylene Oxide Consumable: Steam EO sterilization pouch roll, chemistry indicator strip, biological indicator, chemistry indicator tape, chemical indicator label, EO sterilization gas, medical non-woven fabric, sealing machine, EO sterilization gas.
