What Is A BOD Incubator
BOD stands for Biochemical Oxygen Demand. A BOD incubator keeps samples at a precise low temperature, usually 20°C, so a laboratory can measure how much oxygen microorganisms use to break down organic matter in water. Because it both cools and heats, it is also called a cooled incubator, refrigerated incubator or low-temperature incubator.
How it is used in the BOD test
In water and wastewater laboratories, diluted samples are sealed in BOD bottles and held at 20°C ± 1°C for 5 days, in the dark. Dissolved oxygen is measured before and after, and the difference gives the BOD value. This is the method described in APHA 5210 B and IS 3025 (Part 44). Holding the temperature steady is what makes results comparable between batches and laboratories.
Other ares where BOD Incubators are used:- Cell culture and microbiology requiring temperatures below room temperature
- Fungal and yeast growth
- Fermentation studies
- Seed germination, plant and insect studies (with the lighting option)
- Temperature-controlled storage of sensitive samples and reagents
Difference between General Incubator and BOD Incubator
| PARAMETERS | GENERAL INCUBATOR | BOD INCUBATOR |
|---|---|---|
| Heating | YES | YES |
| Cooling | No | Yes |
| Typical Working Temperature | 21°C | 10°C to 25°C; commonly 20°C |
| Working Below Room Temperature | No | Yes |
| Best Usage | Routine bacteriology at body temperature | BOD test, low-temperature culture, fermentation, plant studies |
NOTE:If your work is all at 37°C, a general incubator is enough. If you need to hold temperatures below ambient, you need a BOD incubator, and it can also run at 37°C when required.
How a BOD Incubator Works
- Load and switch on: Place samples on the trays and power on the unit.
- Set temperature and time: Enter the set value (SV) and timer on the PID controller. The display shows both SV and the actual process value (PV).
- Heat or cool as needed: The controller switches the compressor or the heater so the chamber moves to the set value and stays there.
- Circulate the air: A fan spreads air through the chamber to keep temperature even from shelf to shelf.
- Alarm: The buzzer sounds when the timer ends, and an alarm raises if temperature drifts outside the limit.

How to Choose the Right Capacity of a BOD Incubator
- 50 L: small laboratories and a few BOD bottles per run, or bench-top research.
- 150 L: the most common choice for water testing laboratories running a regular daily batch.
- 350 L and above: high sample volumes, pharma or industrial laboratories, or several users sharing one unit.
As a guide, a model should hold your daily batch with spare room, since bottles need space for air to circulate. e.g. "STXBOD50 holds 32-36 bottles"; Not sure? Tell us your daily sample count and we will recommend a suitable model.
BOD Incubator FAQs
What is a BOD incubator price in India? Prices start from ₹ 60,000/- for a 50 L model and depend on capacity, controller and options. Contact us with your requirement for an exact quotation.
At what temperature is the BOD test carried out? At 20°C ± 1°C for 5 days, in the dark, as per APHA 5210 B and IS 3025 (Part 44).
What is the difference between a BOD incubator and a normal incubator? A normal incubator only heats, so it cannot go below room temperature. A BOD incubator both heats and cools, so it can hold low temperatures such as 10°C or 20°C and can also run at 37°C.
Which capacity BOD incubator should I buy? Choose the one that holds your daily batch with free space around the bottles. 150 L suits most water testing laboratories. Our team can advise from your sample count.
What is the temperature range of a Stericox BOD incubator? All STERICOX BOD Incubators are designed with operating temperature 5°C to 60°C; this range can also be customized based on requirement.
Can I run it at 37°C? Yes, it works across its full range, so it can also do routine incubation. A general incubator is enough if you never need low temperatures.
Is a data recorder available? Yes, a USB data recorder is optional. Fluorescent or LED lights with a 24 × 7 timer and a humidity system are also optional.
How often should a BOD incubator be calibrated and maintained? STERICOX BOD Incubators come with one year standard calibration certificate. After one year, you may hire a calibration agency to calibrate the instrument or just calibrate in-house with a reference thermometer at least once a year, or as per your laboratory's quality protocol. Keep the condenser clean, leave space for air around the unit, and log temperature regularly.
Do you offer delivery, installation and service? Yes, we provide delivery, installation and service all over India.
Do you export? Yes, we also export to the Philippines, Malaysia, Africa, Middle East Countries, Nepal and Bangladesh.
