You Will Understand The Functions And Differences Of Ten Incubators After Reading Them
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 etc.
With so many types, how do they differ?
The incubator, by simulating in the incubator a growth environment similar to cells/ tissues/ microorganisms in the organism or a certain situation, such as a certain temperature, a certain humidity, a certain light or a certain CO2 level, a certain It is a device for culturing cells/tissues/organisms in vitro. It is widely used in the fields of plants, biology, microorganisms, genetics, viruses, medicine, and environmental protection. It is widely used in low temperature and constant temperature experiments, cultivation experiments, Environmental tests and more.
The main types of incubators are as follows:
1. Constant temperature incubator
The constant temperature incubator is suitable for ordinary bacterial culture and closed cell culture, and is often used for pre-warming of equipment and reagents related to cell culture.
Features: heating control, without refrigeration.
The constant temperature incubator is divided into: water-proof constant temperature incubator and electric heating constant temperature incubator.
Water-proof electric heating constant temperature incubator:
The heating tube heats the water in the interlayer and utilizes water convection to form four-sided heating, effectively ensuring heating uniformity. The water jacket can still maintain a good temperature when the power is cut off. Two temperature control methods are adopted: a microcomputer intelligent temperature controller and a bimetal regulator. Temperature control range: room temperature +5°C-60°C, it can only stabilize the temperature above room temperature without refrigeration.
Electric constant temperature incubator:
Electric heating is adopted, the shell is made of cold-rolled plate electrostatic spraying, the inner tank is made of stainless steel, the insulation layer uses asbestos as the insulation material, and there is a heating tube at the bottom to heat the box through the heating tube. Its shortcoming is the temperature The uniformity is relatively poor, and the temperature shock ratio is high. It is mainly composed of several parts such as box body, heater, blower and temperature controller.

3. Biochemical incubator
This incubator is equipped with electric heating wire heating and compressor cooling at the same time. Therefore, it can adapt to a wide range and can be kept at a constant temperature throughout the year, so it is gradually becoming popular. The use and maintenance of this incubator is similar to that of an electric incubator. Since a compressor is installed, precautions for refrigerator maintenance must also be followed, such as keeping the voltage stable, not over-tilting, and cleaning the dust on the radiator in time.
Features: Biochemical incubators generally do not have humidity control and anti-virus functions. It has dual system cooling and heating temperature control. Usually with a glass observation window.
The biochemical incubator is an indispensable laboratory equipment for the scientific research of plants, biology, microorganisms, genetics, viruses, medicine, environmental protection, etc., and the education department. It is widely used in low temperature and constant temperature experiments, cultivation 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 growing at room temperature (25 degrees Celsius), and a certain humidity needs to be maintained when cultivating on a solid substrate, so the general mold incubator is refrigerated System, heating system, air humidifier and cultivation room, control circuit and operation panel, etc., and use temperature sensor and humidity sensor to maintain the stability of temperature and humidity in the cultivation room. Some special mold incubators can also set the temperature and humidity to change with the cultivation time.
Features: dual-system cooling and heating control, heating, cooling, humidity control
This product is suitable for environmental protection, sanitation and epidemic prevention, agricultural 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 analysis; BOD determination of bacteria and mold; cultivation and preservation of microorganisms; plant cultivation and breeding experiments.
5. Carbon dioxide incubator
The carbon dioxide incubator is to form a growth environment similar to cells/tissues in the organism by simulating in the incubator box. The incubator requires a stable temperature (37°C), a stable CO2 level (5%), and a constant pH value (pH value : 7.2-7.4), high relative saturation humidity (95%), a device for in vitro culture of cells/tissues.
Features: temperature control, generally only with heating, high temperature sterilization, some with refrigeration, CO2 level control, pH control, humidity control
Carbon dioxide incubators are widely used in the cultivation of cells, tissue cultures and some special microorganisms. They are commonly used in the study of cell kinetics, the collection of mammalian cell secretions, the carcinogenic or toxicological effects of various physical and chemical factors, the research of antigens 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 increased control of carbon dioxide concentration and the use of microcontrollers to precisely control the temperature of the incubator, the success rate and efficiency of the cultivation of biological cells and tissues are improved. In short, the carbon dioxide incubator is a new type of incubator that cannot be replaced by ordinary electric heating constant temperature incubators.
6. Anaerobic incubator
Anaerobic incubators are also known as anaerobic workstations or anaerobic glove boxes. Anaerobic incubator is a special device for bacterial culture and operation under anaerobic environment. It can provide strict anaerobic constant temperature culture conditions and has a systematic and scientific working area.
Features: anaerobic control, temperature control
This product is a special device for bacterial culture and operation in anaerobic environment. It can cultivate the most difficult anaerobic organisms to grow, and can avoid the risk of death of anaerobic organisms when they are exposed to oxygen when they are operated in the atmosphere. Therefore, the device is an ideal tool for anaerobic biological detection and scientific research.
7. Artificial climate box
The airtight isolation equipment that can artificially control factors such as light, temperature, humidity, air pressure and gas composition is called an "artificial climate box".
