In microbiology, an incubator is an insulated and contained apparatus that offers the ideal temperature, humidity, and other environmental conditions for organism development. An incubator is a piece of essential laboratory equipment used to grow microorganisms under controlled circumstances. The culture of both unicellular and multicellular organisms may be done in an incubator. This is not surprising because, according to incubator microbiology, a stable environment for isolated cells to thrive requires a pH of 7.2 to 7.5, a temperature of 37°C, and relative humidity of 95 percent.
Incubator Principles and Operation
An incubator is based on the idea that microorganisms require a certain set of conditions to grow and thrive.
All incubators are founded on the idea that when organisms are given the right temperature, humidity, oxygen, and carbon dioxide levels, they will develop and divide to produce new organisms.
The thermostat in an incubator maintains a consistent temperature that may be measured with a thermometer from the outside.
Using the heating and no-heating cycles, the temperature is maintained.
The thermostat heats the incubator during the heating cycle, and during the no-heating cycle, the heating is turned off, and the incubator is cooled by radiating heat to the surroundings.
Outside insulation provides an isolated environment within the cabinet, which helps the bacteria to thrive.
Other factors, like humidity and airflow, are also maintained by various methods that produce a habitat that is comparable to the organisms\' native environment.
Similarly, they are given modifications for maintaining CO2 concentrations to maintain the pH and humidity levels necessary for the organisms\' development. A shaking incubator, for example, is a type of incubator that provides for the continual movement of the culture necessary for cell aeration and solubility investigations.
Incubators are used for a broad range of purposes, including cell culture, pharmacological research, hematological research, and biochemical research.
Applications:
The following are some of the applications for incubators:
Microbial cultures and cell cultures are grown in incubators.
Incubators can also be used to keep organisms alive to utilise them later.
Some incubators are used to speed up the growth of organisms that would otherwise grow slowly in the natural environment.
For the reproduction of microbial colonies and subsequent measurement of biochemical oxygen requirements, special incubators are employed. In zoology, they are also employed for insect breeding and egg hatching. Incubators also provide a controlled environment for sample storage before laboratory processing.
Precautions
When using an incubator, take the following safety precautions:
Because bacteria are sensitive to temperature changes, it is best to avoid causing temperature swings in the cabinet by constantly opening the door.
Before the culture plates are placed inside the cabinet, the organism\'s growth conditions must be satisfied.
To avoid water condensation on the media, the plates should be put upside down with the lid at the bottom.
Clean the interior of the incubators regularly to prevent germs from collecting on the shelves or in the corners.
To prevent the culture media from drying out while the incubator is operating for an extended amount of time, sterile water should be put beneath the shelves.
Incubators in microbiology laboratories maintain the environmental conditions at all times. They do not alter until necessary once they have been adjusted to the correct values. The parameters in the incubator can be left unchanged for a few days until the cell culture is suitable for examination and particular application. Incubators provide a stable environment for cultures and microbes to develop and survive by combining natural and induced convection. It has a sophisticated control system and is well-insulated. Incubators use less power, resulting in lower costs and more savings. The parameters can then be adjusted based on the sort of cell culture being stored.
