Incubator is the basic experimental equipment for biological, agricultural, environmental protection, and other scientific research departments. Commonly used incubators include biochemical incubators, carbon dioxide incubators, electric thermostatic incubators, water-tight electric thermostatic incubators, and so on. Each type of laboratory incubator has its own characteristics and unique functions for different fields of scientific research and teaching.

Biochemical incubator is suitable for environmental protection, livestock, drug testing, aquaculture, and other scientific research institutions’ experiments and production departments. It is also a special constant temperature equipment for water analysis and BOD determination, cultivation and preservation of bacteria, mold, microorganisms, plant cultivation, and breeding test.

Mold incubator is suitable for environmental protection, livestock, drug testing, aquaculture, and other scientific research institutions and production departments. It is a special constant temperature equipment for water analysis and BOD determination, cultivation, preservation of bacteria, mold, microorganisms, plant cultivation, and breeding test.

Low-temperature biochemical incubator is an important test equipment for scientific research institutions, universities, and colleges, production units, or departmental laboratories in biology, genetic engineering, medicine, health epidemic prevention, environmental protection, agriculture, forestry and animal husbandry, etc. It is widely used in low-temperature constant temperature tests, culture tests, and environmental tests.

Electric constant temperature incubator is widely used for the cultivation and preservation of bacteria, mold, and microorganisms, and is suitable for medical and health care, the pharmaceutical industry, biochemistry, and agricultural science, and other scientific research and industrial production departments to do bacterial culture, fermentation, and constant temperature test.

Constant temperature and humidity incubator is used for aerospace products, information and electronic instruments, materials, electricians, electronic products, and various electronic components in high temperature or hot and humid environments to test its various performance item indicators. It is commonly used in food, cosmetics, environmental monitoring, electronics, rubber, and other fields.

The light incubator is widely used in microbial tissue cell culture, seed germination, seedling test, plant cultivation, and insect and small animal rearing, etc. It can accurately simulate different environmental and climatic conditions.

A device for in vitro culture of cells/tissues by stimulating the formation of an environment similar to the growth of cells/tissues in an organism in an incubator chamber, which requires a stable temperature (37°C), a stable CO2 level (5%), a constant pH (pH: 7.2-7.4), and a high relative saturation humidity (95%), and is a cell, tissue, and bacterial culture. The CO2 incubator is an advanced instrument and key equipment necessary for conducting immunology, oncology, genetics, and bioengineering.

Microbiological incubator with natural convection circulation and no noise to avoid sample evaporation during the test. Used for microbiology culture, yeast or other microorganism growth, storage, and testing.

The anaerobic incubator is a special device for bacterial culture and operation under anaerobic environmental conditions. It can provide a strict anaerobic state of constant temperature incubation conditions and has a systematic and scientific working area.

Low-temperature incubators are widely used for storage of culture media, serum, drugs and microbial culture, environmental testing, etc.

Water-tight thermostatic incubator has high precision thermostatic equipment, a water-tight heating method to ensure a uniform temperature in the studio, and in the power-off state, it can still keep the thermostat for a long time. It can be used for the tissue of plants, germination, cultivation of seedlings, cultivation of microorganisms, rearing of insects and small animals, BOD determination of water quality testing, and constant temperature test for other purposes. It is the ideal equipment for production, scientific research, and education departments of biological genetic engineering, medicine, agriculture, forestry, environmental science, animal husbandry, and aquaculture, etc.

Incubators are widely used in research and production in medicine, immunology, genetics, microbiology, agricultural sciences, and pharmacology. They have become one of the most common and routine instruments used in laboratories in these fields by stimulating the formation of a culture chamber that simulates the growth environment of a cell/organism in a living organism such as a constant pH (7.2-7.4), a stable temperature (37 "C), and a stable temperature (3.5-7.4). (37 "C) too high relative humidity (95%) for the in vitro culture of cells/tissues.

Users have two basic requirements for a laboratory incubator. The first is that the incubator provides the most accurate and stable control of temperature and humidity to facilitate the progress of their research, and the second is that the incubator provides effective protection against microbial contamination in the incubator and can be decontaminated regularly to protect research results and prevent sample loss.

Both air-jacketed and water-jacketed heating systems are accurate and reliable, and both have their own advantages and disadvantages.
Both have their advantages and disadvantages.

The advantages of water-jacketed heating are that water is a good insulator, and in the event of a power failure, the water-jacketed system can maintain temperature accuracy and stability in the incubator for a relatively long period of time (3-4 times longer than the gas-jacketed system), which is beneficial for experimental environments that are less stable (e.g., with power restrictions or frequent power outages) and require long periods of time. The gas-jacketed system is used by users who need to maintain stable incubation conditions over a long period of time.

Gas-jacketed heating is the direct heating of the inner chamber by means of heaters in the air-jacketed layer of the chamber, also known as six-sided direct heating.

Compared with the water jacket type, the air jacket type has the characteristics of rapid heating and temperature recovery than the water jacket type incubator, especially for short-term incubation and incubation that requires the door to be opened and closed frequently. In addition, the air-jacketed design is simpler for the user than the water-jacketed design (the water-jacketed design requires a filling, emptying, and cleaning of the tank, and constant monitoring of the tank operation).

Maintaining a constant temperature in the incubator is an important factor in maintaining healthy cell growth, so an accurate and reliable temperature control system is an essential part of the incubator. Users choose incubators with triple temperature control functions that are independent of each other, i.e., internal temperature control, over-temperature alarm control, and ambient temperature monitoring for stable incubator operation.

Temperature uniformity within the incubator is also a major consideration for the user. Generally, incubators equipped with fans and ducts in the chamber are much more uniform, and the device also facilitates rapid recovery of the temperature and relative temperature inside the chamber.

Humidity in the chamber is a very important yet often overlooked factor for culture work. Maintaining adequate humidity levels and level and a fast enough recovery rate (e.g., after opening and closing the door) to ensure that the culture does not fail due to excessive dryness. The culture will not fail due to excessive dryness. When choosing an incubator, it is important to choose one with a large humidity area, because we know that the larger the humidity area, the easier it is to reach the maximum relative saturation humidity and the shorter the recovery time after opening and closing the door.

Contamination is a major factor in cell culture failure, so incubator manufacturers have designed a variety of devices to reduce and prevent contamination, primarily by minimizing the areas and surfaces where microorganisms can grow and by incorporating automatic contamination removal devices to effectively prevent contamination. Some have designed and produced HEPA filters to filter the air inside the incubator to remove 99.97% of particles above 0.3 microns, and have also developed and designed incubators to kill contaminating microorganisms for disinfection purposes by bringing the incubator to a high temperature, humid and hot environment. These devices are indispensable for cell culture.

The disinfection power of UV is inversely proportional to the distance of the UV lamp from the target, the further the distance, the less disinfection power.

High-temperature moist heat is more efficient than dry heat sterilization because of the high latent heat of the steam and strong penetration, which can easily denature or coagulate proteins. There are three reasons for this.

a. The temperature required for protein coagulation is related to its water content, the higher the water content, the lower the temperature required for coagulation to occur. Humid heat sterilization of the bacterium protein absorption of water, so the more agreeable temperature of the dry hot air is easy to coagulate.

b. The moist heat sterilization process releases a large amount of latent heat from steam, which accelerates the increase of humidity. Thus, the temperature required for wet heat sterilization is lower than that required for dry heat, and the time required for wet heat sterilization is shorter than that for dry heat, if at the same temperature.

c. The penetrating power of moist heat is greater than that of dry heat, which makes it possible to reach the sterilization temperature even in the deep part, so moist heat has a somewhat better effect than dry heat. So high temperature sterilization does not simply look at the temperature of sterilization, but mainly at whether wet heat sterilization.
