The thermostat provides the desired temperature and maintains the temperature during heating and non-heating cycles. The control panel is outside the cabinet and has many switches to control different parameters of the incubator. Note: Unlike a hot air oven there is glass for visualizing contents in the incubator. The gaskets prevent hot air from escaping outside the cabinet and non-sterile air from entering the cabinet.
Asbestos door gaskets provide air tight seal between the door and the cabinet. The door has glass for visualizing the contents present inside the cabinet.
The door is present at the front part of the incubator. The storage capacity of the cabinet ranges from 20 liters to 800 liters. The glass wool insulates the gap between the double-wall to prevent heat loss. The inside of the cabinet is made up of aluminum, whereas the outside is made up of stainless steel. The cabinet of the incubator is double-walled. Parts of a laboratory incubator Cabinet with Door The laboratory incubatory has the following parts: A thermometer displays the temperature inside the instrument. When the incubator reaches the desired temperature, the contractor is de-energized, temporarily shutting off the power supply. The bulbs are the heating element of the incubator, and fans ensure equal hot air distribution in the incubator. Once the power is supplied to the incubator, the contractor is energized, which powers the bulbs.
The temperature control depends on the temperature sensor, controller, and contractor. The temperature inside the incubator increases when power is supplied. For example, the suitable incubation temperature for mesophilic bacteria is 37℃, whereas for molds and yeast, it is 28℃. Thus, the formed thermal gradient generates a thermoelectric effect which is a voltage.Ī predetermined temperature is set in the instrument because different microorganisms require different temperatures for growth. The thermostat in the incubator maintains a constant temperature by creating a thermal gradient. The basic principle of a laboratory incubator depends on the thermo-electricity principle, i.e., heat or thermal energy converts into electrical energy.
