The biochemical incubator refers to the temperature-controllable enclosure device used to culture microbial, plant, and animal cells, and some of the models have a bidirectional thermostat system of refrigeration and heating. It can accurately simulate the climate conditions in different environments, compact, stackable, energy-efficient, and exceptionally reliable. It is special constant temperature equipment for water analysis and BOD determination, culture, preservation, plant cultivation, and breeding of bacteria, mold, and microorganisms. This biochemical incubator is the essential device of biochemical, agriculture, medicine, environment protection, and other scientific and research.
