Second hand top three 10 cubic ethylene oxide sterilization cabinetThe low dosing rate of the ethylene oxide sterilization cabinet may affect the sterilization effect. It is necessary to check the equipment parameter settings and hardware status, and refer to relevant standards for adjustment and verification.
According to the operating specifications of the sterilizer, the dosing rate is one of the important parameters affecting the sterilization effect5During the operation, it should be ensured that the sterilization cabinet can accurately control the injection rate and amount of ethylene oxide to ensure the sterilization effect.
Equipment parameter inspection
Check if the dosing system of the sterilization cabinet is working properly, including components such as dosing pumps, pipelines, and valves
Confirm whether the temperature and pressure parameter settings of the equipment meet the requirements, as temperature and pressure can affect the vaporization and injection effect of ethylene oxide1
Standard requirements comparison
According to relevant standards, the ethylene oxide sterilization cabinet should have accurate dosing control capabilities5The equipment should be able to regulate the temperature and humidity inside the cabinet, and ensure that the injection rate of ethylene oxide meets the sterilization process requirements.
Verification method
Biological indicator method can be used to verify the sterilization effect5By placing Bacillus subtilis var. niger spore slices at different positions in the sterilization cabinet, conducting full load sterilization treatment and cultivation testing, evaluate whether the sterilization effect meets the requirements.
adjustment suggestions
If the dosing rate is indeed low, it is recommended to contact the equipment manufacturer for professional maintenance and calibration
Check for pipeline blockages or insufficient power of the dosing pump
Ensure proper maintenance and upkeep of the equipment to avoid a decrease in dosing rate due to equipment aging
It should be noted that changing the dosing rate may affect the entire sterilization process, so any adjustments should be fully validated to ensure that the sterilization effect is not affected
