What is bacteriological incubator?
In laboratory, there are two types: bacteriological incubator and BOD incubator.
Bacteriological incubator is mainly used in the laboratory for the growth of bacteria. It has a thermostat that maintains a constant temperature setting as needed. An accurate temperature can be seen on a thermometer fixed to the incubator.
Most bacteriological incubators are programmable and do not require trial and error with temperature settings. The incubator only has a heating system that maintains the temperature at which bacteria grow. These incubators are affected by the ambient temperature as there is no cooling system.
What is BOD incubator?
BOD incubator is
called low temperature incubator and are used for yeast and mold growth because they require low temperatures to grow. This incubator is called BOD (Biological Oxygen Demand
) because low temperatures around 20-25°C are required in the biological oxygen demand incubator
test, so not to be confused with the term, as the purpose of a BOD incubator
is also the same as a bacterial incubator . There is both a cooling system and a heating system in a BOD chamber
, which makes it different from a bacterial incubator. BOD incubators are not affected by the surrounding environment and are completely independent.
What is incubator?
Incubator is a device in which the cultivation process is carried out, the housing is regulated to a predetermined temperature, as it provides and maintains all artificial optimal conditions for the growth of the microbial culture.
What is incubation?
Incubation is a period of time during which temperature, humidity, and other environmental variables provide the desired temperature level for the growth and development of a microbial culture.
Why do we need incubation temperature and time?
We all know that if culture is not provided, every organism has a latency period for growth and development, which will surely degenerate any organism. Therefore, culturing is an important aspect for proper growth and development.
Function of bacteriological incubator
is a kind of incubator to culture molds, the function of this incubator is to culture biology and plant, and then set the corresponding temperature and humidity in a confined space so that the bacteria can grow for about 4-6 hours. Therefore, laboratory bacteriological incubator
is a piece of testing equipment that is suitable for the cultivation of mold and another eukaryotic microorganisms.
Bacteriological incubator parts
Because most molds are suitable for growing at the room temperature which is about 25 degrees Celsius, and need to maintain certain humidity when culturing on a solid substrate, the general bacteriological incubator is consisted of refrigeration system, heating system, air humidifier and culture room, control circuit and operation panel and other small parts. In addition, there have temperature sensor and humidity sensor which are used to maintain the stability of temperature and humidity in culture room.
Bacteriological incubator working principle
In simple terms, the temperature sensor in the bacteriological incubator converts the actual temperature into electrical signals, which are transmitted to the microcomputer. Then the microcomputer works according to the preset temperature parameters and then controls the refrigeration compressor or heater to reach the specified temperature in the incubator so that it cultivates the desired bacteria.
How bacteriological incubator work?
The bacteriological incubator work depend on the thermoelectric principle. The incubator has a thermostat that maintains a constant temperature by creating a thermal gradient. When any conductor is subjected to a thermal gradient, it produces a voltage called the thermoelectric effect.
A predetermined temperature (37˚C) was set in the incubator when power was applied to the circuit. This temperature is maintained through the compatible operation of temperature sensors, temperature controllers and temperature contactors, which are the main components. When turned off, current flows into the system, which energizes the contactor, which powers the light bulb that acts as the heating element of the system, and a fan that ensures the distribution of hot air throughout the system when the temperature in the system reaches the desired value (37) ˚C), the digital temperature controller sends an electrical signal to the contactor, which de-energizes, temporarily shutting down the heater. Likewise, when the temperature drops beyond the desired temperature, the contactor will energize again, turning on the system.
Bacteriological incubator temperature
Ideal temperature and incubation time:
Bacteriological incubator: 48 hours (2 to 3 days) between 30°C and 37°C
BOD incubator: 72 hours (3-5 days) between 20°C and 25°C
Where bacteriological incubator can be used?
Bacteriological incubator is used to accelerate the growth and reproduction of mold, storage species, as well as the cultivation of other types of microorganisms special incubator laboratory. Bacteriological incubator can also be used to examine the mildew resistance of electronic components and electronic products, and test and judge product performance changes in a hot and humid environment. In artificial three climate protection, this incubator is important testing equipment. Therefore, a bacteriological incubator is widely used in the fields of environmental protection, drug testing, agriculture, livestock, epidemic prevention, water analysis, BOD determination, bacteria, mold, microbial culture in the laboratory, plant cultivation, and breeding experiment.

SOP for bacteriological incubator
The full name of SOP is a standard operating procedure, as important experimental testing equipment in the laboratory, the standard use of bacteriological incubator must be clear. The following is the correct operation method of bacteriological incubator:
1. Plugin eh power, and then press the power switch of the bacteriological incubator, the actual temperature and humidity inside the incubator will be shown on the display screen.
2. Connect the humidifier to the power socket on the back of the bacteriological incubator, and then connect the humidifier pipe to the humidifier, and check whether the humidifier is tightly connected or not. Add water to the humidifier tank, if the humidifier malfunction, repair it according to the warranty points on the humidifier manual.
3. Adjust the temperature which you want according to the press temperature button.
4. If the actual temperature in the incubator is lower than the set temperature, the heat indicator lights up and starts heating. Otherwise, the refrigeration indicator light is on, and the refrigeration system starts to refrigerate.
5. Adjust the humidity by pressing the humidity setting button. If the actual humidity in the incubator is lower than the set humidity, a humidification indicator light will be on, and the incubation chamber for humidification.
6. Because the humidity sensor is in a high humidity state for a long time, the humidity display value keeps high. If the humidity value wants to be accurate, bacteriological incubator should open the door after using it, to let the humidity sensor be at room temperature, and then can continue to use after natural drying.
7. Please unplug the bacteriological incubator when the incubator stops using.
8. To maintain the appearance of the incubator, please do not wipe the surface with acid or alkali or other corrosive materials. The incubator can clean regularly with a dry cloth.
How to clean bacteriological incubator?
Bacteriological incubator is a device that is specially used in the experiment. It provides a good growth environment for the data collection of many microorganisms. However, after many times of use and cultivation, the residuum will leave in an incubator, which will affect the later test and research if the bacteriological incubator is not cleaned in time, and it can affect the service life of the machine.
Therefore, we must pay attention to the daily cleaning of the bacterial incubator, and here are 4 common cleaning methods for bacteriological incubator:
1. After removing dirt and debris from the interior and exterior, using low-concentration alcohol to wipe the wall, ventilate for 10minutes and then use ultraviolet light for 30minutes to complete simple disinfection
2. Under the circumstance that does not have ultraviolet rays illuminate, use 70% ethanol to scrub commonly, and then scrub with 0.1% bromogeramine, and then use Potassium Permanganate1:1 ratio for disinfection. It should be noted that, due to the irritating taste, the bottom of the incubator can not be put anything before sterilization, this way is to prevent the solution and corroding the glassware.
3. You can also use formaldehyde to sterilize bacteriological incubator, but the characteristic of formaldehyde is toxic, explosive, flammable, and volatile, you should use it carefully and avoid the residue of formaldehyde after disinfection because it will affect the culture of the microorganism.
4. The last method is to use disinfectant for sterilization, but bacteriological incubator has sensors to detect temperature and humidity, disinfectant is generally corrosive, which might cause the damage to sensors, so you should be very careful when using a disinfectant. This disinfection method is not recommended.
What is difference between BOD incubator and bacteriological incubator?
In laboratory experiments, bacteriological incubator and BOD incubator are the most commonly used instruments. Although they are very similar in the appearance and function, these two machine has an emphasis and differences which can be divided three main differences:Functional difference
The most obvious functional difference between bacteriological incubator
and BOD incubator is temperature control function and disinfection function. Bod incubator does not contain moisture and sanitizer functions. However, Bacteriological incubator has both functions. In addition, bacteriological has two options of humidification and no humidification, BOD incubator has no humidity choice. Application difference
is also called biochemical incubator, it is suitable for the analysis of the water body, determining BOD, bacteria and microorganism culture
, preserving and planting plant and breeding test, enzyme and enzyme engineering research, biology, medical products, vaccines, blood, and various specimens preserved. It is mainly used for biochemical reactions of a hatch, to be able to observe its particular temperature incubation reaction. Therefore, the door of BOD incubator is mainly composed of double vacuum glass, which can effectively isolate the interaction of temperature inside and outside the incubator, and enable the operator to observe the change of reaction outside without destroying the reaction conditions. It can also be used for the cultivation of bacteria, mold, and control bacteria.
Bacteriological incubator is widely used in colleges and universities, medicine, electronics, chemical industry, biological scientific research
departments for all kinds of mold, microorganism, tissue cell culture, storage bacteria, also can be used for insects, small animals feeding and other purposes of constant temperature test. Compared with BOD incubator, bacteriological incubator has increased sterilization function, which is installed with ultraviolet sterilization lamp, using ultraviolet sterilization principle to kill mold spores. This function can provide pure culture space for the cultivation of microorganisms, and BOD incubator does not need to be installed with an ultraviolet sterilization lamp.Bacteriological incubator price VS BOD incubator price
Bacteriological incubator and BOD incubator can be used for bacterial culture, but the function of bacteriological incubator is more complete than BOD incubator. It can be used instead of a BOD incubator. But it is also because the function of a bacteriological incubator is more, the price in the same volume of Bacteriological incubator is slightly more expensive than a BOD incubator.
Bacteriological incubator VS BOD incubator
