    How to choose suitable ETO sterilizer
    How to choose suitable ETO sterilizer

    Choose the size of sterilizer according to the daily output of materials
    According to the difference of packaging space of products and cartons, the throughput of each time is slightly different. Each time of sterilization is 8-12 hours, and it can work for 2 cycles every day.

    Three standard types of sterilizers

    BE: Basic Type, Meet YY0503/ISO11135
    LE: General Type, CE Standard, Meet EN1422/ISO11135
    GE: Advanced Type, CE standard, Meet EN1422/ISO11135

    Q:Amount of ethylene oxide consumed by ethylene oxide sterilizer per time
    A: 0.6-0.8 kg / m3. Each consumption of  ethylene oxide is 3.6-4.8kg. Ethylene oxide is a dangerous chemical, which is not suitable for long-distance transportation and can be purchased nearby.

    Sterilization process

    Sterilization process: packaging → sterilization → analysis → testing → delivery.
    1. The products shall be packed in cartons
    2. Put the products into the sterilization cabinet for sterilization (8-12 hours)
    3. Take the products out of the sterilization cabinet and analyze it.There are three options for analysis: forced analysis of sterilizer, or analysis room, or directly placed in a well ventilated workshop.
    4. After analysis, it is tested to be qualified and sold on the market
    Respirator sterilization is to use ethylene oxide gas for sterilization. After sterilization, ethylene oxide gas residue should be removed. The process of removing ethylene oxide residue is defined as analysis.

    How long does it take to resolve the products after sterilization with ethylene oxide.

    1. If natural parsing is used, it will take about 14 days.
    2. If the analysis room is used, it will take about 5 days.
    3. If the sterilization cabinet is used for analysis, it will take 2.5 days. This requires that the sterilization cabinet has a forced resolution function, which is forced to resolve for 12 hours, and then placed naturally for 2 days.
    It only takes 12 hours to parse directly in the sterilizer. This kind of equipment adopts our new technology and greatly reduces the parsing time. Our products have advantages.
    It can be parsed directly in the sterilization cabinet, which has requirements for packaging. Dialysis packaging is needed, or small pieces of dialysis paper are left on the packaging. In order to save packaging cost, a dialysis window can be added to the packaging. Then the dialysis bag is analyzed for 12 hours, and taken out for natural analysis, that is, it is placed for 2 days.
    The time needed for the analysis is different due to the different process. As long as the content of ethylene oxide is below the standard, it is possible to use any analytical method, mainly depending on the choice of customers.

    We suggest using the analysis room.

    Most of the products and medical equipment factories use sterilizer internal analysis or analytical room analysis?
    Most of the medical instrument factories use analytical room. The supporting equipment also includes tail gas treatment equipment.

    Q:What kind of packaging is more convenient for sterilization

    A:1. It is recommended to use dialysis bag for products packaging, otherwise the sterilization cycle will be longer. Sterilization dialysis bag packaging for 8 hours (with preheating).
    2. Packaging is the first step. After packing, sterilize, analyze and test.
    Analysis depends on whether it is directly in the sterilization cabinet, or placed in the analysis room, or natural analysis.
    It takes 12 hours to parse directly in the sterilizer. If there is an analysis room, it will take 5 days; if it is natural, it will take 14 days if it is well ventilated.
