These types of incubators are often called low temperature incubator used for the growth of yeast and mold as they require low temperature to grow.
Desirable Temperature and duration of incubation – Between 30˚C to 35˚C for 48 hours (2 to 3 days)īOD incubator (Low Temperature Incubator) These incubators are affected by temperature of surrounding environment because no cooling system is present. This incubator has only heating system which maintains the temperature for growth of bacteria.
#BOD INCUBATOR TEMPERATURE TRIAL#
Most of the incubators are programmable which do not need trial and error temperature setting. Accurate temperature can be seen on thermometer fixed on incubator. it has a thermostat which maintains a constant temperature set according to requirement. This type of incubator is used mainly in laboratory usually for the growth of bacteria. In pharmaceuticals industry, there are two types of incubator are used : Also when temperature reduces beyond desire temp.the contactor will be energized again thus switch on the system. When the switch off, current flows into the system thereby energizing the contactor that powers the bulbs which serves as heating elements to the system, the fan ensures Distribution of hot air in the entire system.when the temperature in the system gets to desirable(37˚C) the digital temperature controller sends an electrical signal to contactor which de-energized thereby switching off the heaters temporarily. This temperature is maintained by the compatibility operation of the temperature sensor, temperature controller and temperature contactor are major components. When any conductor is subjected to a thermal gradient, it generates voltage called as thermo-electric effect.Īs power is supplied to the circuit predetermined temperature (37˚C) is set in the incubator.
The incubator has a thermostat which maintains a constant temperature by creating a thermal gradient. Principle and working of incubator : incubator depends on the principle of thermo-electricity. We all know every organism has a incubation period for growth and development if incubation is not provided it will definitely degenerate the growth of any organism so incubation is important aspect for the proper growth and development. Why we need incubation temperature and time What is Incubation Incubation Is a period of time in which temperature, humidity and other environmental variables are provide desired temperature level for the growth and development of microbial culture. Incubator Incubator Is a device in which incubation process is done which conditions an enclosure to a predetermined temperature because it provides and maintains all artificial optimal conditions for growth of microbial culture.
