BOD Incubator: Principle, Types, and Usage
A BOD (Biochemical Oxygen Demand) incubator is a specialized laboratory instrument designed to maintain a controlled environment for biological and biochemical studies, particularly for the measurement of BOD in wastewater and other environmental samples.
1. Principle of BOD Incubator
The principle of a BOD incubator is to provide a stable and uniform temperature for the incubation of microbial cultures, particularly for determining the Biochemical Oxygen Demand (BOD) of water samples. The incubator maintains a constant low temperature (usually 20°C ± 1°C) over a specified period (typically 5 days in BOD testing).
The incubator works by controlling temperature precisely, using a thermostatic or microprocessor-based temperature control system.
A cooling system (compressor-based refrigeration) and a heating element work together to maintain the required low temperature.
Forced air circulation (via fans) ensures uniform temperature distribution within the chamber.
The sample bottles or test media inside the incubator undergo microbial activity, consuming oxygen and thus allowing accurate BOD measurement.
