![]() Temperatures range from ambient to 100 degrees Celsius.It has a basic function of temperature control and insulation. Most of the laboratories contain Benchtop incubators.These are classified based on the types of parameters or the purpose of the incubator. There are different types of incubators in microbiology. Incubator diagram | Image Source: Types of Incubator in laboratory It separates the hot environment of the cabinet from the external environment and prevents the outside air from entering the cabinet.It provides an airtight seal between the door and the cabinet.The shelves contain perforations which help in the movement of hot air throughout the inside of the incubator. ![]() These shelves are removed, which means we can clean them properly.The plates of culture media are placed over it. It is located on the inner wall of the incubator.It constantly maintains the specified temperature within the incubator by the heating and no-heating cycles.It is used to achieve the desired temperature within the incubator.It also controlled the thermostat device.It consists of many switches and indicators which monitor the different parameters of the incubator. It is located at the outer of the incubator.There also presents a glass door that enables the visualization of the interior of the incubator.The incubator contains an insulated door that encloses the insulated cabinet.It prevents heat loss from the incubator. To provide insulation to the incubator the inner gap between the inner wall and outer wall is filled with glass wool.It consists of an inner wall which is made of aluminum and an outer wall which is made of stainless steel sheets.The cabinet is made of a double-walled cuboidal enclosure.The parts of an incubator are (i) Cabinet Components of an IncubatorĪn incubator is made up of different parts or components which help to maintain the optimum condition required for the bacteria growth. Some incubators also contain a shaker or aeration device which continuously shake the culture for cell aeration and solubility studies. Similarly, the incubator also maintains the other parameters such as humidity, airflow, co2 concentration, pH, through different mechanisms which are required for the growth of the organisms. The cabinet contains an insulation system that separates it from the outside and allows the microbes to grow effectively. In heating cycle, the thermostat increases the temperature of incubator whereas in the non-heating cycle the incubator is cooled by radiating heat to the surrounding. By utilizing the heating and no-heating cycles we maintain the inside temperature of the incubator. We can monitor this temperature from the outside via the thermometer. Incubator contain a thermostat which maintains the inside temperature of the incubator. An incubator provides an optimum level of temperature, humidity, oxygen, and carbon dioxide so that the microorganism can multiply and increase their numbers. Working Principle of IncubatorĪll incubators work based on a simple principle that microorganisms require an optimum environment for their growth and development. Both bacterial and eukaryotic cell organisms are cultivated by using an incubator. In laboratories, it is used to grow and maintain microbiological cultures or cell cultures. It creates an optimum environment which is required for the growth of microorganisms by providing optimum temperature, humidity, and other environmental conditions such as the CO2 and oxygen content inside’s atmosphere. An incubator is an insulated and enclosed device used in biological laboratories.
