2 should be used with high-pressure steam sterilization precautions
( 1 ) try to exclude the air sterilizers : You must have the device when using autoclaves air drained . If there is the presence of air in the sterilizer , the sterilization temperature will affect reasons: steam mixed with air, it will affect the thermal conduction time of the pressure in the right as shown , and heat is not consistent , and thus resulting in incomplete sterilization . There kiln retained partial retention effect , making it difficult to penetrate the heat , even the formation of temperature stratification , so sterilization should pay close attention to the temperature of the pot . Check that the air drained methods are: install a thermometer in the exhaust port , such as the exhaust gas temperature reaches 100 degrees Celsius when the air has drained pot instructions ; hose in the exhaust port set to the other end opening into the cold water basin , and if small bubbles emerging, there is still an air discharge instructions .

Various Sterilization Introduction

Various Sterilization Introduction

Sterilization by means of a suitable physical or chemical means to kill microorganisms living in the article or method to remove. This law applies to sterile preparation , raw materials, accessories and medical equipment and other items . Sterile refers to goods does not contain any living micro-organisms . However, for any number of steam bottle sterilizer products, both can not guarantee absolute sterility test can not be used to confirm . Physical or chemical means sterilization tests showed : kill microorganisms on the number of rules to follow , therefore , sterile sterilized items after items sterilization standards generally microbial survival probability – sterility assurance level SAL (Sterility Assurance Level) said . Probability of surviving microorganisms terminally sterilized product shall not exceed 10-6. Sterilized products meet the sterility assurance level can be determined by verification. Sterilization and sterility assurance products can not rely on sterility testing of the final product , but on the process used in the production of qualified sterilization process , strict management and good GMP comprehensive quality assurance system. Sterilization process should be determined by considering the nature of the items to be sterilized , effective and economic method of sterilization , the sterilization integrity and stability of the article and other factors .
Validate the sterilization process is a necessary condition of sterility assurance . Sterilization process validated only after the delivery of official use. Verify that include:

Also considered a dry heat sterilization . IR generated by the infrared lamp , no conduction through the air , the faster the heating rate , the heat radiation effect can only be produced to the surface and therefore can not make an object before and after uniform heating around . Bactericidal effect is similar to an infrared dry heat , temperature and time required likewise sterilized using infrared oven dry roasted . Used for sterilization of medical devices.

People affected by infrared radiation longer feel eyestrain and headaches ; prolonged exposure can cause damage to the eye . Therefore, the working people should at least be able to wear anti- infrared goggles injury .

Advantages And Disadvantages Of Dry Heat Sterilization And Moist Heat Sterilization

Advantages And Disadvantages Of Dry Heat Sterilization And Moist Heat Sterilization

Due to the high temperature steam heat latent heat , penetrating power, easy or coagulation protein denaturation , thus the high efficiency of the method of sterilization than dry heat sterilization .

There are three reasons : ① coagulation proteins related to the temperature required for its water content , the greater the water content , the lower the temperature required for coagulation . Moist heat sterilization of bacterial proteins absorb moisture , so dry compared to the same temperature as the hot air is easy to set.

② moist heat sterilization process steam release a lot of latent heat , and improve humidity. Thus the desired heat than dry heat sterilization temperature is low , as at the same temperature, the heat than dry heat sterilization time is short .

③ heat penetration than dry heat large, it can reach deep sterilization temperature , the thermal effect is better than dry heat . More details on http://www.autoclavesale.com/ .So pasteurized not simply look at sterilization temperatures , mainly to see whether the heat disinfection. In addition, from the use of perspective, heat sterilization is generally controlled 90 ° C can be achieved in a very thorough disinfection , the entire disinfection process all attachments are not removed within the incubator , can all be disinfected ; rather dry heat sterilization in order to achieve more good results, temperatures are generally in the 100 ° C or more, must be taken during the sterilization process in which the temperature sensor , HEPA filter sterilized inside the incubator , etc. , etc. disinfected and then loaded on the end , so that trouble, accessories and can not be disinfected , but also increases the chance of secondary pollution Moreover to reach temperatures above 100 ° C incubator heating wire heating system is bound to bold , which leads to increased difficulty in controlling the temperature of the incubator , uniformity becomes poor.
