Test tube basket in the laboratory
How to sterilize the laboratory?
A. Thermal sterilization
High temperatures denature or coagulate (structural changes leading to loss of function) the proteins and enzymes of microorganisms, and the metabolism is impaired and dies, thus achieving the purpose of disinfection and sterilization. In disinfection, heat can be divided into two categories: moist heat and dry heat.
B. Dry thermal sterilization
Dry heat is high heat with a relative humidity of 20% or less. Dry heat disinfection and sterilization is conducted by air, and the heat transfer effect is slow. The general propagules can be killed in dry heat 80-100℃ after 1 hour, and the budding cells need 160-170℃ after 2 hours to be killed.
a. Combustion method is a simple, rapid and thorough sterilization method, which has limited application because of the destructive nature of the items.
b. Some instruments that are resistant to high temperatures (metal, enamel type) can be cauterized in an emergency or when no other method of disinfection is available. Place the instrument on a flame and cauterize it for 1-2 minutes. For enameled containers, pour a small amount of 95% ethanol, slowly rotate the container so that the ethanol is evenly distributed, and ignite the flame until it is extinguished for about 1-2 minutes. When collecting specimens for bacterial culture, before and after the specimen (i.e., after opening the lid, before closing the lid) should be placed on the mouth and lid of the test tube (bottle) burned on the flame, rotating back and forth 2-3 times. When burning, pay attention to safety, must be away from flammable and explosive substances, such as oxygen, gasoline, ether, etc.. Burning process shall not add ethanol, so as not to cause flame upward and cause burns or fire. Sharp knives and scissors should not be sterilized by burning in order to protect the blade.
c. Certain special infections, such as tetanus, gas gangrene, Pseudomonas aeruginosa infected dressings, and other items that have been contaminated and have no retention value, such as soiled paper and garbage, should be placed in an incinerator and burned to char them.
C. Electric heating incubator
Sterilization using hot air from the incubator. The incubator is heated by electricity and the air is constantly convected in a certain space, producing a homogeneous effect of hot air to directly penetrate the object. General propagules can be killed in dry heat 80-100 ℃ after 1 hour, budding cells, viruses need 160-170 ℃ after 2 hours to kill. The hot air sterilization method is suitable for glassware, porcelain and gelatin sponge, liquid paraffin, various powders, etc. After sterilization, wait until the temperature inside the box drops to below 50-40℃ before opening the door to prevent blowing up.
D. Microwave sterilization
Microwave is a high-frequency electromagnetic waves, its sterilization principle of action, one is the thermal effect, where the molecules produced by the internal violent movement, so that the object inside and outside the humidity rises rapidly; one is a combination of effects, such as chemical effects, electromagnetic resonance effect and field commitment effect. At present, it has been widely used in the sterilization of food and pharmaceuticals, with microwave sterilization of surgical instruments, microbiological laboratory supplies, etc. have also been reported. If the goods first by 1% peroxyacetic acid or 0.5% Neosporin wet treatment, can play a synergistic sterilization effect, irradiation for 2 minutes, can make the rate of killing bud cells from 98.81% to 99.98% -99.99%. Use can be set impervious to microwave metal barrier or wear special protective glasses, etc.
E. Boiling method
Boil the water to 100℃, keep it for 5-10 minutes to kill the propagules, and keep it for 1-3 hours to kill the sprouting cells. When adding sodium bicarbonate to 1%-2% concentration in water, the boiling point can reach 105℃, which can enhance the sterilization effect and also can decontaminate and prevent rust. In the case of low air pressure and low boiling point in highland areas, the disinfection time should be extended (for every 300m increase in altitude, the disinfection time should be extended by 2 minutes). This method is suitable for enamel, metal, glass and rubber items that are not afraid of humidity and high temperature.
Before boiling, clean the items, open the shaft section or lid, and submerge them all in water. Bowls and pots of the same size should not be overlapped to ensure that all sides of the item are in contact with the water. Sharp, small, fragile items are wrapped in gauze to avoid impact or scattering. Glass and enamel are put in cold or warm water; metal and rubber are put in after the water boils. The disinfection time starts from the boiling water. If the items are added in the middle of the process, the timing is re-timed and the items are removed promptly after disinfection to maintain their sterile state.
F. Autoclaving method
The autoclave is tightly installed, the input steam does not escape, the temperature increases with the increase of steam pressure, and when the pressure increases to 103-206kPa, the humidity can reach 121.3-132℃. High-pressure steam sterilization is the use of high pressure and high heat release of latent heat for sterilization, the public number "laboratory ISO17025" reminded that this method is currently a reliable and effective sterilization method. It is suitable for items that are resistant to high temperature and pressure and not afraid of moisture, such as dressings, surgical instruments, drugs, bacterial culture media, etc.
Latent heat refers to the heat of 2255.2J released when lg100℃ water vapor becomes lg100℃ water.
The key issue of autoclaving is to provide good conditions for heat conduction, and the most important of them is to make the cold air discharged from the sterilizer smoothly. Because of the poor thermal conductivity of cold air, which prevents steam from contacting the sterilized items, and can also reduce the partial pressure of steam so that it does not reach the proper temperature.
G. Portable autoclave sterilizer
A metal cylinder, divided into two layers, holds water in the compartment, has a cover that can be screwed on, and produces steam after heating. There is a pressure gauge outside the pot, and when the steam pressure rises, the temperature also rises accordingly. The sterilizer is small, self-generating steam, and easy to carry.
