Finally clearly! The functions and differences of 10 laboratory incubators
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. What is the difference between such a variety of classes? The incubator simulates the growth environment of a cell/tissue/microbe in the living organism or in a specific situation, such as a certain temperature, a certain humidity, a certain light or a certain CO2 level, by a certain amount in the incubator. A device for in vitro culture of cells/tissues/organisms, such as pH, is widely used in plants, biology, microbiology, genetics, viruses, medicine, environmental protection, etc., and is widely used in cryostat tests, culture tests, Environmental testing and more. The incubator mainly has the following types The constant temperature incubator is suitable for common 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: a water-proof constant temperature incubator and an electrothermal constant temperature incubator. Water-blocking electrothermal constant temperature incubator: The heating tube heats the water in the interlayer, and uses the convection of water to form four-sided heating, which effectively ensures heating uniformity. The water jacket can still be well thermostated when it is powered off, and adopts two kinds of temperature control methods: a microcomputer intelligent temperature controller and a bimetal regulator. Temperature control range: room temperature +5 ° C -60 ° C, can only stabilize the temperature above room temperature, without refrigeration. Electrothermal constant temperature incubator: adopts electric heating method, the outer casing adopts cold-rolled plate electrostatic spray, the inner liner is made of stainless steel, the thermal insulation layer uses asbestos as insulation material, and the heating pipe is arranged at the bottom, and the heating body is heated through the heating pipe. Its disadvantage is that the temperature uniformity is relatively poor and the temperature is relatively high. It is mainly composed of a cabinet, a heater, a blower and a temperature controller. 2 constant temperature and humidity incubator The constant temperature and humidity incubator can accurately simulate a complex natural environment such as constant temperature and constant humidity, and has a box with precise temperature and humidity control system. Features: temperature control, humidity control, generally without observation window Generally used in plant culture, breeding tests; microbial culture, fermentation and other constant temperature tests, environmental tests, material denaturation tests and storage of media, serum, drugs and other items. Widely used in medical and health, bio-pharmaceutical, agricultural research, environmental protection and other research applications. This incubator is equipped with both electric heating and compressor cooling. Therefore, the adaptability range is large, and the temperature can be maintained at a constant temperature throughout the year, and thus it is gradually popularized. The incubator is similar to the electric heating incubator. Due to the installation of the compressor, the precautions for the maintenance of the refrigerator should also be observed. For example, keep the voltage stable, do not over-tilt, and clean the dust on the radiator in time. Features: Biochemical incubators generally do not have humidity control and no anti-virus function. With dual system cooling and heating temperature control. Generally with a glass observation window. The biochemical incubator is an indispensable laboratory equipment for plant, biology, microbiology, genetics, viruses, medicine, environmental protection, etc. It is widely used in cryogenic constant temperature test, culture test, environmental test, etc. The mold incubator is a test equipment suitable for the cultivation of eukaryotic microorganisms such as molds, because most molds are suitable for growth at room temperature (25 degrees Celsius), and a certain humidity is required to be cultured on a solid substrate, so the general mold incubator is cooled. The system, heating system, air humidifier and culture room, control circuit and operation panel are used, and temperature sensor and humidity sensor are used to maintain the stability of temperature and humidity in the culture chamber. Some special mold incubators can also set the temperature and humidity as the culture time changes. Features: dual-system hot and cold control, heating, cooling, humidity control This product is suitable for environmental protection, health and epidemic prevention, agricultural and livestock, drug testing, aquatic products and other scientific research, college experiments and production departments. It is water body analysis; BOD measures bacteria and mold; culture and preservation of microorganisms; special constant temperature and constant temperature oscillation equipment for plant cultivation and breeding experiments. The carbon dioxide incubator simulates the formation of a similar cell/tissue growth environment in the organism by incubating the incubator. The incubator requires a stable temperature (37 ° C), a stable CO 2 level (5%), and a constant pH (pH). Value: 7.2-7.4), higher relative saturation 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 culture of certain specific microorganisms, commonly in cell dynamics studies, 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. Since the carbon dioxide concentration control is increased, and the temperature of the incubator is precisely controlled using a microcontroller, the culture success rate and efficiency of biological cells, tissues, and the like are improved. In short, the carbon dioxide incubator is an irreplaceable new incubator for ordinary electrothermal incubators. Anaerobic incubators are also known as anaerobic workstations or anaerobic glove boxes. The anaerobic incubator is a special device for bacterial culture and operation under anaerobic conditions. It provides a constant anaerobic state with constant temperature culture conditions and a systematic, scientific work area. Features: anaerobic control, temperature control This product is a special device for bacterial culture and operation in an oxygen-free environment. It can cultivate the most difficult anaerobic organisms and avoid the risk of death from contact with oxygen when anaerobic organisms operate in the atmosphere. Therefore, this device is an ideal tool for anaerobic bioassay research. A closed isolation device that can manually control factors such as light, temperature, humidity, air pressure, and gas composition is called an "artificial climate chamber." Features: lighting control, humidity control, hot and cold control, air pressure control, gas composition control The artificial climate chamber is a high-precision hot and cold thermostat with illumination and humidification function, providing users with an ideal artificial climate experimental environment. It can be used for plant germination, seedling, tissue, microbial culture; feeding of insects and small animals; determination of BOD for water analysis and artificial climate test for other uses. It is an ideal test equipment for production and scientific research departments such as biological genetic engineering, medicine, agriculture, forestry, environmental science, animal husbandry, and aquatic products. The light incubator is a high-precision thermostat with illumination function. It is a special constant temperature culture device for the cultivation and breeding experiments of bacteria, molds and microorganisms. It is especially suitable for scientific research in the fields of bioengineering, medical research, agriculture and forestry science, aquatic products and animal husbandry. Production use. Features: lighting control, constant temperature control (cooling and heating) The housing of the light incubator is generally cold-rolled steel plate, the surface is electrostatically sprayed, the inner liner is engineering plastic or stainless steel, the thermal insulation layer is formed by polyester foam, and the light-transmissive window is double-layered insulating glass to ensure the thermal insulation performance inside the box. Inside the body, the gas circulation in the cold and hot air ducts is smooth and the temperature is more uniform. The light incubator is mainly used for plant cultivation, and the microbial incubator has different types depending on the type of microorganisms to be cultured. The plant incubator is actually a light-incubating incubator with humidity, in which the conditions of light, temperature and humidity can meet the growth needs of plants. The principle of the plant incubator is several sets of tubes and a temperature control device (usually 5-50 degrees). If there are lighting settings at the advanced point, such as when the lights are turned off, when the lights are strong, etc. Features: lighting control, humidity control, constant temperature control, dedicated to plant culture Low temperature incubators are widely used in storage media, serum, pharmaceuticals, microbial culture, environmental testing, and the like.
