BOD Bottle, with Interchangeable Glass Stopper

The GISCOM BOD Bottle with Interchangeable Glass Stopper is a precision-engineered laboratory bottle designed for accurate Biological Oxygen Demand (BOD) measurements. It provides an ideal closed environment for determining dissolved oxygen levels in water, wastewater, and environmental samples. Manufactured from high-quality Borosilicate Glass 3.3, it ensures exceptional chemical durability, thermal stability, and long-term reliability. This bottle is essential for water testing laboratories, environmental monitoring facilities, and industrial QC labs requiring accurate and repeatable BOD analysis.

Key Features

• Interchangeable Glass Stopper: Provides an airtight seal to maintain sample integrity and prevent oxygen infiltration.

Handling & Precautions

• Handle with care to avoid breakage of the neck or stopper joint.
• Clean using mild laboratory detergents; avoid abrasive materials.
• Ensure the stopper and neck joint are completely dry before use to ensure an airtight closure.
• Autoclave at recommended temperatures only (do not exceed 121°C unless specified).
• Avoid sudden temperature changes to maintain glass integrity.
• Store in a padded rack or safe area to prevent accidental impact.
• Do not use with highly corrosive chemicals above the recommended limits.

Applications

• Water & Wastewater Analysis: Standard BOD5 and extended BOD testing.
• Environmental Monitoring: Evaluation of dissolved oxygen in natural water bodies.
• Pharmaceutical QC Labs: Water purity analysis, dissolved oxygen studies.
• Chemical & Biotech Industries: Process water testing and effluent monitoring.
• Academic & Research Institutions: Environmental science studies, hydrology projects.
• Industrial Laboratories: Routine compliance testing per regulatory requirements.

The bottle plays a crucial role in creating a controlled, oxygen-limited environment for accurate BOD determination—an essential parameter for wastewater treatment plants, environmental audits, and pollution monitoring.
