BOD Incubator

A specialized laboratory incubator designed to maintain a precise and stable temperature environment, typically between 20°C and 25°C, for the biochemical oxygen demand (BOD) test, which measures the amount of oxygen consumed by microorganisms in a water sample.

Types of BOD Incubator

Standard BOD Incubators: Basic models offering temperature control for BOD tests.

Refrigerated BOD Incubators: Essential for maintaining temperatures below ambient (e.g., 20°C for standard BOD).

Programmable BOD Incubators: Allow for multiple temperature setpoints and cycles for various applications.

Large Capacity BOD Incubators: For high-volume testing, often with multiple shelves.

Illuminated BOD Incubators: With internal lighting for plant growth studies or other applications (though not strictly for BOD).

Applications in Various Industries

Environmental Laboratories: Primary application for BOD testing of water and wastewater samples.

Water Treatment Plants: Quality control and compliance monitoring.

Food & Beverage Industry: Microbiological testing, shelf-life studies.

Pharmaceutical Industry: Stability testing of drugs and chemicals.

Research & Development: Microbiology, biotechnology, cell culture (where precise low temperature control is needed).

Technology:

Precise Temperature Control: PID microprocessor control for tight temperature uniformity and stability.

Refrigeration System: Compressor-based cooling for maintaining temperatures below ambient.

Forced Air Circulation: Internal fan for uniform temperature distribution.

Inner Glass Door: Allows observation of samples without disturbing the internal environment.

Digital Display & Controls: For easy setting and monitoring.

Safety Features: Over-temperature protection, alarm systems.

Data Logging: Some models offer data recording capabilities.

Material Selection Considerations

• Inner Chamber: Stainless steel (304 or 316) for corrosion resistance, hygiene, and ease of cleaning.
• Outer Casing: Powder-coated mild steel or stainless steel for durability and aesthetics.
• Insulation: High-density PUF (polyurethane foam) or mineral wool for efficient thermal insulation and energy saving.
• Shelves: Stainless steel wire mesh or perforated sheets.
• Door Gaskets: Magnetic rubber gaskets for a tight seal.
• Refrigeration Components: Copper tubing for refrigerant lines, standard compressor components.
• Controller & Sensors: Electronic components, platinum resistance thermometer (Pt100) for temperature sensing.
