BOD (biochemical oxygen demand)

Automated BOD analyzers for precise oxygen consumption testing.

MANTECH’s Automated BOD Analyzers – Precision in Biochemical Oxygen Demand Testing

MANTECH offers a range of instruments for Biochemical Oxygen Demand (BOD) analysis, designed to accommodate laboratories of all sizes and testing needs.

BIOCHEMICAL OXYGEN DEMAND (BOD)

Whether you require a manual or automated system, with small or large sample capacity, MANTECH provides customized solutions for every laboratory.

MANTECH’s automated BOD systems are robust, equipped with user-friendly software, and deliver fast, reliable results.

KEY ADVANTAGES

Fully automated 7-day BOD and CBOD analysis, compliant with ASTM 5210B, ISO EN 18991, and ISO EN 18992
Minimizes human error with automated reagent addition (supports up to five pumps per instrument), automatic rinsing between samples, and more
Intuitive user interface for easier operation
Efficient sample management, including prioritization of samples during analysis
Rapid access to results with barcode scanning for sample tracking

10-MINUTE BOD ESTIMATION

MANTECH has introduced a new automated BOD system package that includes a rapid 10-minute BOD estimation, performed alongside the standard 7-day automated test.

This combination provides the perfect instrument solution for laboratories handling high sample volumes, offering a faster indication of BOD levels. It is particularly useful for process optimization, such as chemical dosing adjustments.

ENVIRONMENTAL/WATER SAMPLE ANALYSIS

BOD analysis is a critical parameter in wastewater monitoring and is conducted by most laboratories analyzing environmental and water samples.

7-day BOD testing comes with strict requirements for sample handling, preparation, storage, and analysis. The time factor is the most crucial aspect, as oxygen demand (OD) in a sample changes rapidly over time. Additionally, dilution factors applied during sample preparation must be carefully controlled.

Due to strict acceptance criteria for oxygen saturation measurements before and after the 7-day incubation period, multiple test attempts are often required to obtain valid results—retesting a failed sample is not an option.

Given these challenges, laboratory operators face significant pressure to ensure traceability, correct sample preparation, accurate dilution, and precise analysis execution.
