Carbon dioxide incubator sterilization and disinfection related matters - Database & Sql Blog Articles

inductance

The volume of the carbon dioxide incubator is a factor that cannot be ignored. It is not enough for small, and it is wasteful and takes up space. Users need to have a more accurate understanding of the range of required incubator volume before purchase, and reserve a little space on this basis to ensure that it is needed. In addition, each user wants the instrument to be easy to use, micro-processing control system and other various functional accessories (such as high temperature automatic adjustment and alarm device, CO2 alarm device, password protection setting, automatic calibration system, LCD display system). The use of, etc., makes the operation and control of the carbon dioxide incubator very simple. Although the names of different microprocessor systems are different, the principle and control effect are not different. You don't have to care too much about the difference between their names when purchasing. The key is to make it easy to use and easy to operate.

High temperature sterilization is divided into high temperature dry heat sterilization and high temperature moist heat sterilization. High-temperature damp heat has high latent heat and strong penetrating power, which tends to denature or solidify proteins. Therefore, the sterilization efficiency of this method is higher than that of dry heat sterilization. There are three reasons for this:

1) The temperature required for protein coagulation is related to its water content. The higher the water content, the lower the temperature required for solidification to occur. The moist heat-sterilized bacterial protein absorbs moisture, so it is easy to coagulate in dry hot air at the same temperature.

2) During the moist heat sterilization process, the steam releases a large amount of latent heat, which accelerates the humidity. Thus, moist heat sterilization is lower than the temperature required for dry heat, and at the same temperature, the time required for moist heat sterilization is shorter than dry heat.

3) The penetration of damp heat is larger than that of dry heat, so that the deep part can also reach the sterilization temperature, so the damp heat is better than the dry heat. Therefore, high temperature sterilization is not a simple look at the disinfection temperature, mainly to see if it is hot and humid.

In addition, from the point of view of use, wet heat disinfection is generally controlled at 90 ° C to achieve a very thorough disinfection effect, all the accessories in the incubator are not taken out during the entire disinfection process, can be completely disinfected; and dry heat disinfection in order to achieve better The effect is that the temperature is generally above 100 ° C. At this temperature, the sensor in the sterilization incubator, the HEPA filter, etc. must be taken out during the sterilization process, and then the disinfection is completed and then installed, which is troublesome, and the accessories cannot simultaneously Disinfection, and increase the probability of secondary pollution, and in addition to reach a high temperature above 100 ° C, the heating wire of the heating system of the incubator must be thickened, which will lead to increased difficulty in temperature control of the incubator, uniformity is worse. Therefore, the user selects an incubator containing a high-temperature moist heat sterilization method when purchasing a carbon dioxide incubator.
