Wheaton 227497 300mL BOD Bottle for Biochemical Oxygen Demand Testing

The Wheaton 227497 BOD Bottle is a precision-engineered laboratory vessel designed for biochemical oxygen demand (BOD) testing of diluted samples including sewage, polluted waters, and industrial effluents. Constructed from high-quality USP Type I borosilicate glass, this 300mL bottle adheres to the specifications outlined in the *Standard Methods for the Examination of Water and Wastewater* (21st Edition, 5210B, 2005), making it essential for environmental monitoring, wastewater treatment analysis, and molecular diagnostics in bioprocessing environments.

Key technical features include:

• Specially designed bottle shoulder radius that ensures complete removal of air during sample filling, critical for accurate aerobic biochemical oxygen demand measurement.
• Interchangeable tapered stoppers to prevent air entrapment and enable secure incubation conditions.
• Flared mouth design to create a water seal around the stopper, preventing external air contamination during incubation periods.
• Compatibility of stopper joints with probes from leading manufacturers for BOD and dissolved oxygen measurements, facilitating integration with oxygen meter probes widely used in cell culture and synthetic biology research.
• Permanently screened-on large numbering and writing patches for sample identification and traceability.

This bottle is widely adopted in biotechnology laboratories focusing on aquatic bioprocessing, molecular biology workflows, and biomanufacturing processes, where reliable oxygen demand measurements are critical for process control and environmental compliance. Its robust glass construction ensures chemical resistance and durability essential for repetitive use in clinical diagnostics and water quality labs.

The product supports precise monitoring of aerobic biochemical degradation, fundamental in biomedical engineering research and environmental biotechnology applications such as bioremediation studies and industrial waste characterization. The 300mL volume is optimized for the standard five-day BOD incubation period, providing accurate and reproducible analytical results.
