The incubator is a very common laboratory instrument, but we often encounter various incubators, such as: constant temperature incubator, constant temperature and humidity incubator, carbon dioxide incubator, anaerobic incubator, mold incubator, light incubator and many more.
With so many types, how do they differ?
The incubator simulates a growth environment similar to cells/tissues/microorganisms in organisms or a specific situation in the incubator, such as a certain temperature, a certain humidity, a certain light or a certain CO2 level, a certain pH, etc., is a device for in vitro culture of cells/tissues/organisms. It is widely used in plants, biology, microorganisms, genetics, viruses, medicine, environmental protection and other fields. It is widely used in low temperature and constant temperature experiments, culture experiments, Environmental testing, etc.
There are mainly the following types of incubators:
1.constant temperature incubator
The constant temperature incubator is suitable for common bacterial culture and closed cell culture, and is often used for pre-warming equipment and reagents related to cell culture.

The constant temperature incubator is divided into: water-proof constant temperature incubator and electric heating constant temperature incubator.
Waterproof electric heating constant temperature incubator:
The heating tube heats the water in the interlayer and uses the convection of the water to form four-sided heating, which effectively ensures the uniformity of heating. The water jacket can still be kept at a constant temperature in case of power failure, and two temperature control methods are adopted: a microcomputer intelligent temperature controller and a bimetal regulator. Temperature control range: room temperature +5℃-60℃, the temperature can only be stabilized above room temperature without refrigeration.
Heated Incubators:
The electric heating method is adopted, the outer shell is made of cold-rolled plate electrostatically sprayed, the inner tank is made of stainless steel, the insulation layer is made of asbestos as the insulation material, and there is a heating tube at the bottom, and the box is heated through the heating tube. Its disadvantage is the temperature The uniformity is relatively poor, and the temperature impulse is relatively high. It is mainly composed of box, heater, blower and temperature controller.

Widely used in medical and health, biopharmaceutical, agricultural scientific research, environmental protection and other research applications.
3.Biochemical incubators
This kind of incubator is equipped with electric heating wire heating and compressor cooling at the same time. Therefore, it can adapt to a large range and can be maintained at a constant temperature throughout the year, so it is gradually popularized. The use and maintenance of this incubator is similar to that of an electric heating incubator. Due to the installation of a compressor, the precautions for maintenance of the refrigerator should also be observed, such as keeping the voltage stable, not tilting too much, and cleaning the dust on the radiator in time.
Features: Biochemical incubators generally do not have humidity control and antivirus functions. With dual-type cold and hot temperature control. Generally with glass observation window.
Biochemical incubators are indispensable laboratory equipment for scientific research and education departments such as plants, biology, microorganisms, genetics, viruses, medicine, environmental protection, etc., and are widely used in low temperature and constant temperature experiments, culture experiments, and environmental experiments.
4.mold incubator
The mold incubator is a test equipment suitable for cultivating eukaryotic microorganisms such as mold. Because most molds are suitable for growth at room temperature (25 degrees Celsius), and a certain humidity needs to be maintained when culturing on a solid substrate, the general mold incubator is refrigerated. System, heating system, air humidifier and culture room, control circuit and operation panel, etc., and use temperature sensor and humidity sensor to maintain the stability of temperature and humidity in the culture room. Some special mold incubators can also set the temperature and humidity to change with the incubation time.
Features: dual-type cooling and heating control, heating, cooling, humidity control
This product is suitable for environmental protection, sanitation and epidemic prevention, agriculture and livestock, drug inspection, aquatic products and other scientific research, college experiments and production departments. It is a special constant temperature and constant temperature oscillation equipment for water body analysis; BOD determination of bacteria and molds; microbial culture and preservation; plant cultivation and breeding experiments.
5.CO2 incubator
The carbon dioxide incubator simulates a growth environment similar to that of cells/tissues in vivo in the incubator. The incubator requires stable temperature (37°C), stable CO2 level (5%), and constant pH (pH value). : 7.2-7.4), high relative saturated humidity (95%), a device for in vitro culture of cells/tissues.
Features: temperature control, generally only with heating, high temperature sterilization, individual refrigeration, CO2 level control, pH control, humidity control
Carbon dioxide incubators are widely used in cell, tissue culture and the culture of some special microorganisms, commonly used in cell dynamics research, collection of mammalian cell secretions, carcinogenic or toxicological effects of various physical and chemical factors, antigen research and Production and cultivation of hybridoma cells to produce antibodies, in vitro fertilization (IVF), stem cells, tissue engineering, drug screening and other research fields.
Due to the increase of carbon dioxide concentration control and the use of microcontroller to accurately control the temperature of the incubator, the success rate and efficiency of biological cells, tissues, etc. have been improved. In short, the carbon dioxide incubator is a new type of incubator that cannot be replaced by ordinary electric heating incubators.
6.Anaerobic incubators
Anaerobic incubators are also known as anaerobic workstations or anaerobic glove boxes. Anaerobic incubator is a special device for bacterial culture and operation in anaerobic environment. It can provide strict anaerobic constant temperature culture conditions and a systematic and scientific working area.
