Wheaton BOD Bottle 227667 300 mL (Black PVC Coated)

Wheaton BOD Bottle 227667 300 mL (Black PVC Coated)

The Wheaton 300 mL BOD Bottle with black PVC coating (cat. no. 227667) is designed specifically for water-quality and environmental testing—and for situations where you need to block light completely. The outer black PVC coating prevents visible light penetration up to ~800 nm, making it ideal for dark-bottle or “light vs dark” comparative testing such as BOD (Biochemical Oxygen Demand) assays.

Key Features

• Manufactured from Type I borosilicate glass for high chemical and thermal resistance.

• External black PVC plastic coating blocks all visible light up to ~800 nm, helping to eliminate light-driven oxygen production (e.g., from algae) during incubation.

• Comes with a glass robotic stopper and an opaque black over-cap (depending on packaging).

• 300 mL capacity matches standard BOD test volumes.

• Ideal for “dark bottle” experiments or where you must ensure the sample is completely shielded from light.

Specifications

• Brand: Wheaton

• Model: 227667

• Capacity: 300 mL

• Material: USP Type I borosilicate glass

• Coating: Black PVC plastic external coating blocking visible light to ~800 nm

• Typical dimensions: Diameter ~73 mm; Height ~167 mm (case referenced)

• Packaging: Usually sold in cases of 20.

Applications

• Use it for BOD testing, particularly when you need a dark bottle to compare “lighted” vs “dark” conditions or to prevent photosynthetic oxygen generation in the sample.

• Suitable for water/waste water analysis, environmental monitoring, and other labs where light exclusion is critical.

• Works for storage and incubation of samples where light exposure could alter the result or degrade the sample.

Maintenance & Handling

• Inspect the bottle before use; check for chips or cracks as damage may compromise light-exclusion or integrity.

• Use the supplied stopper and cap (or equivalent) to seal the bottle properly.

• Clean with mild detergent; rinse thoroughly and dry before reuse.

• Avoid using violent thermal shock; although borosilicate is durable, the PVC coating may be affected by extreme heat.

• Store upright in a stable, light-controlled area if you are preserving samples against light exposure.
