Bod Bottles - Glass Stopper

BOD Bottles with Glass Stoppers are high-precision laboratory glassware containers specifically designed for incubating diluted samples of clean water, wastewater, effluent, and polluted liquids to determine their Biochemical Oxygen Demand (BOD). Fabricated from premium borosilicate glass, these specialized bottles provide an optimized incubation environment for checking dissolved oxygen depletion over standard testing periods (such as 5-day incubation assays).

The bottle design features a specialized flared lip or water-seal collar that holds a small reservoir of water around the joint during incubation, completely preventing atmospheric air from drawing into the bottle. Each bottle is fitted with a precision-ground interchangeable glass robotic stopper featuring a distinct tapered bottom. This unique conical stopper profile displaces all internal air when inserted, ensuring an absolutely airtight, bubble-free liquid fit that protects sample integrity from external oxygen contamination.

Key Features

• Manufactured from high-purity borosilicate 3.3 glass for exceptional optical clarity and maximum chemical inertness
  
• Flared water-seal mouth configuration designed to maintain an external fluid barrier against ambient air migration
  
• Precision-ground interchangeable glass stopper with a sharp, pointed bottom profile to prevent air bubble entrapment
  
• Available with clear white or permanent black-enamel marking spots for efficient numbering and batch sequence recording
  
• Uniform wall thickness distribution with a reinforced flat base for stable placement on laboratory work surfaces and shaker trays
• International Standards

Our BOD incubation bottles are engineered and manufactured in strict compliance with globally accepted environmental testing standards and scientific dimensions, making them ideal for international distribution and public tenders:

• EPA Method 405.1 – Guidelines for Biochemical Oxygen Demand Analysis Compliance
  
• Standard Methods 5210B – Joint IPC/APHA Standard Guidelines for BOD Testing Analysis
  
• ASTM E438 – Standard Specification for Glasses in Laboratory Apparatus Manufacturing (Type I, Class A)
• Standard capacity is 300ml (with optional 60ml variants available). Bottles can be ordered in unnumbered sets, consecutively numbered sequences, or matched sets with barcode markings to integrate seamlessly with automated robotic dissolved oxygen probes and LIMS tracking setups.

Applications

Extensively utilized across municipal wastewater treatment plants, industrial effluent monitoring labs, environmental pollution testing centers, public health sanitation facilities, and commercial water quality auditing agencies.
