Difference between Bacteriological incubators, BOD incubators and Co2 incubators

• Microbiology laboratory incubators used  for incubation purpose.
• Microbiology laboratory mainly used 3 types of incubators for microbial growth.
• Bacterial growing purpose required temperature 30-35⁰ C for 2-3 days, Fungal growing purpose required temperature 20-25⁰ C for 5-7 days.

1. Bacteriological incubators
2. BOD incubators (Biological oxygen demand or Biochemical oxygen demand)
3. Co₂ Incubators

1. Bacteriological Incubators:

• Used for bacterial growth purpose.
• Bacteriological incubators provide ambient temperature for growth of bacteria.
• ambient temperature means relating to the surrounding temperature.
• It can some basic heating machines.
• It fails in cold weather.
• If the room where it is stationed has right ambient temperature, it can still work. 

2. BOD incubators:

• Biological oxygen demand or Biochemical oxygen demand
• Used for the growth of fungal (Yeast and Molds).
• BOD incubators mainly used for lower incubation purpose.
• BOD incubators is called Low temperature incubators and refrigerated incubators.
• BOD incubators has full control over the temperature as it is provided, with both heating and cooling arrangements and provides ±0.5⁰ C variation over the set temperature.
• BOD incubators contains heating coils as we as compressor for cooling process.
• BOD incubators is an incubation designed to maintain 20⁰C necessary to perform a test called Biochemical Oxygen Demand (BOD).
  
  

3. Co₂ Incubators:

• Carbon dioxide must be controlled.
• Mainly used for Anaerobic bacteria enumeration purpose.
