Product Description

Ethylene oxide sterilizers sales



Ethylene oxide sterilizers does not damage the sterilized articles and has a strong penetrating power.Therefore, most articles that should not be sterilized by ordinary methods can be sterilized and sterilized with ethylene oxide.For example, electronic instruments,optical instruments, medical instruments,books,documents,fur,cotton,chemical fiber,plastic products,wood products,ceramics and metal products,endoscopes, dialyzers,and disposable medical supplies.Ethylene oxide sterilizers is one of the most important methods of low-temperature sterilization at present.The sterilization mechanism of ethylene oxide is through its non-specific alkylation with microorganisms,thereby inhibiting the normal function of microbial reaction groups and causing their metabolism to occur. Obstructed and died.The sterilizing effect of ethylene oxide is related to the temperature, pressure,humidity,and concentration of ethylene oxide in the sterilization chamber.These process parameters can shorten the sterilization time and achieve the best sterilization effect with appropriate values.Therefore,the working process of the sterilizer first warms the sterilization chamber until the temperature reaches a predetermined sterilization temperature;then,the sterilization chamber is evacuated,and when the predetermined degree of vacuum is reached,the sterilization chamber is started to be filled;After the above process is finished,the fixed clock starts to work and the sterilization process starts;during the entire sterilization process,the temperature needs to be maintained; when the sterilization time arrives,the sterilization chamber starts to be ventilated,ie the filtered clean air is used.Replacing the residual ethylene oxide gas in the sterilization chamber and discharging the residual gas;the residual gas is discharged after being processed by the exhaust gas treatment system
Ethylene oxide sterilizers according to the analysis of the properties of ethylene oxide,the factors affecting the sterilization effect are temperature,humidity,concentration,time,pressure,and packaging methods.
1,temperature:
The normal temperature limit is generally 37°C~63°C,the most commonly used temperature is generally 50±5°C.However,when the temperature is high enough to maximize the effect of the drug, the bactericidal effect is no longer improved when the temperature is raised.The determination of the sterilization temperature is related to the following conditions:1) Temperature tolerance of the extinguished product.2) The loading capacity and loading method require that the loading volume be≤80%,and the cabinet wall should not be touched. There should be a clearance of not less than 5cm between each cabinet.3)The thickness, size, and bulk density of packaging materials.
2,humidity
The moisture content of the sterilized article,the degree of drying of the microorganism itself,and the relative humidity of the environment all have an effect on the sterilizing effect of EO.When the relative humidity is lower than 30% RH,the sterilization effect is significantly affected. Therefore,wet microbes are easier to extinguish than dry ones,but the extermination effect is not proportional to the relative humidity.The humidity is too high and EO is diluted and hydrolyzed.Therefore, the humidity before dosing after vacuuming should be controlled within the range of 30%RH to 80%RH.
3,pressure
The degree of pre-vacuum determines the amount of residual air,and the amount of residual air affects the pressure after the EO is added and the ease with which the hot and humid heat enters the interior of the article.Therefore,the pressure, especially the pressure before humidification,has a great influence on the sterilization effect.The pressure should be set according to the sealing performance of the equipment itself and the positive and negative pressure resistance of the extinguished items.In the equipment operation and the objects can withstand,the vacuum sterilization generally has a better effect than the positive pressure sterilization.
4,ethylene oxide concentration
As an important factor affecting the sterilization effect,the sterilization effect can be enhanced by increasing the concentration.In a certain concentration range,when the other conditions such as temperature and humidity are the same,as the concentration increases,the time required to exterminate and kill a certain concentration of microorganisms is shorter,and the killing effect is better.
5, time
Under the same conditions,the longer the sterilization time,the smaller the survival probability of microorganisms and the better the sterilization effect.In addition to time other than the same conditions of the parameters,determine the shortest effective time(half-cycle)of ethylene oxide without viable bacteria,the process requirements of the action time
