What is the difference between BOD incubator and incubator?

Answer 1

An ordinary incubator is generally based on ambient temperature for growth of bacteria. It can have some baic heating arrangements. It fails in cold weather. If the room where it is stationed has right ambiant temperature, it can still work. BOD Incubator has full control over the temperature as it is provided with both heating and cooling arrangements and provides +/- 0.5 Degree C variation over the set temperature. It does not provide control over relative humidity. The Environmental chamber provides control over Temperature and relative humidity.

Answer 2

A BOD incubator is an incubator designed to maintain 20°C necessary to perform a test called Biochemical Oxygen Demand (BOD). It involves incubating samples saturated with oxygen at 20°C for (usually) five days. Such an incubator has a compressor to depress the temperature below ambient and a heater to bring it back up to 20°C. These work against each other and produce very precise temperature control, often as close as +/-0.1°C. The term "incubator" is a general term which includes BOD incubators and other incubators designed to maintain other temperatures. The term used unqualified usually refers to an incubator designed to maintain temperatures of 5°C or more above ambient to as high as 100°C. Incubators designed to maintain temperatures below ambient to as low as about 10°C are generally called low-temperature incubators. Devices that maintain colder temperatures are called refrigerators or freezers.
