The last issue talked about how to choose a drying oven, those who want to inquire can browse upwards, this issue talks about how to choose an incubator. Incubator as a reduced environmental simulation equipment, according to the temperature, humidity, light, air composition and culture of samples, size, etc., derived from a variety of incubator types, now the incubator to do under the classification, while briefly introduce the use, I believe that you will have an understanding of the incubator after reading.
1, Electric constant temperature incubator: the basic incubator models, the principle of hot air circulation heating, the temperature range is generally room temperature +5 ℃ to 65 ℃, there is also to 105 ℃, no refrigeration function, mainly used for bacterial culture, plant growth, seed nursery, yeast fermentation and other constant temperature test with, in particular, the food factory used to cultivate E. coli special incubator.
2, Water-isolated constant temperature incubator: while using water as a heat transfer and insulation material incubator, the advantage of high uniformity, power failure can maintain a long time thermostat, the temperature range is generally room temperature +5 ℃ ~ 65 ℃, the role of the same as the above electric thermostat incubator.
3, Low temperature incubator: also called low temperature preservation oven, with refrigeration and heating functions, the general temperature range in 5 ℃ ~ 65 ℃, there are to 100 ℃. Often used in the storage of culture media, serum, drugs and microbial culture, environmental testing, etc.
4, Biochemical incubator: refrigeration and heating functions, the temperature range is relatively wide, -60 ℃ ~ 105 ℃ at various stages are available, the scope of application is very large, is biological, genetic engineering, medicine, health epidemic prevention, environmental protection, agriculture, forestry and animal husbandry industries such as scientific research institutions, universities and colleges, production units or departments of the laboratory of basic test equipment.
5, Mold incubator: temperature range with biochemical incubator, the main difference is that the interior of the oven is equipped with ultraviolet sterilization lamp, the internal sterilization of the oven used to provide a pure environment for microbial culture.
6, Constant temperature and humidity incubator: general temperature range in 0 ℃ ~ 65 ℃, increased humidity control, humidity control range 10 ~ 90% RH, while achieving accurate control of temperature and humidity. Widely used in microorganisms, drugs, food processing, industrial raw materials, electronic products, furniture products, metal materials, etc. in high and low temperature or hot and humid environment to test its performance indicators.
7, Light incubator: the upgraded version of biochemical incubator, including refrigeration and heating functions, increased light function, temperature range in 0℃~65℃. Mainly simulate various environments, widely used in a variety of biological tissue, bacteria and mould microbial culture, plant selection and breeding, seed germination, animal and insect breeding, etc.
8, Artificial climate chamber: the upgraded version of constant temperature and humidity, both light, humidification function of high-precision cold and hot constant temperature equipment, temperature range in 0 ℃ ~ 65 ℃. Commonly used in plant growth and tissue culture, seed germination, seedlings, microbial culture test; insects and small animals rearing; water quality monitoring BOD determination; medicine, wood, building materials aging and life testing, and other uses of light, constant temperature, constant humidity of special test equipment.
9, Carbon dioxide incubator: conventional electric thermostat incubator improvement, adding CO2 gas in the chamber to simulate the formation of a similar cell, tissue growth environment in the organism, the tissue, cells or microorganisms in vitro culture, is immunology, oncology, genetics and biological engineering of key equipment.
10, Three gas incubator: carbon dioxide incubator based on the improvement, adding nitrogen and oxygen, controlled by computer and adjust the content of a variety of different gases, belongs to a high-end incubator, used for the reproduction and cultivation of some special microorganisms.
11, Anaerobic incubator: also known as anaerobic workstation or anaerobic glove oven, is a special equipment for cultivation and operation under anaerobic environmental conditions, it can provide a strict anaerobic state of constant temperature cultivation conditions and has a systematic, scientific work area.
12, Oscillating incubator: according to the oven environment can also be divided into artificial climate oscillating incubator and CO2 oscillating incubator, etc. It can also be said that the above incubator classification can be designed as an oscillating incubator, the sample is dynamically stored in the oven. They are particularly suitable for the oscillation of biological samples for a variety of comparative tests and are widely used for cell culture, fermentation, hybridisation, biochemistry and cell tissue research.
From the above classification it can be concluded that understanding the environment in which the experimental samples are to be cultured is the key to choosing which incubator to use, firstly for temperature, secondly for the air environment inside the chamber, then for humidity and light etc. Of course, the user's needs as a starting point, continuous technological innovation and the development of a variety of incubators, which is a trend of progress. So, how to choose culture, priority reference to their own configuration parameters, and then a collection of budget to choose the configuration of high and low series. Tip, a little high-end incubator, some times can be used as a lower level incubator, such as constant temperature and humidity chamber can be used as a mold culture or even as an electric incubator, without re-purchasing.
