BOD Bottle 300ml

The BOD Bottle 300ml is a laboratory bottle used for biochemical oxygen demand testing of water and wastewater samples. Its 300 mL nominal capacity supports BOD laboratory procedures in environmental, water-quality, educational and research laboratories where dissolved oxygen is measured before and after controlled sample incubation.

Product Description

The STEMAids BOD Bottle 300ml is intended for holding water or wastewater samples during biochemical oxygen demand analysis. In the conventional five-day BOD test, dissolved oxygen is determined before and after incubation, allowing the oxygen consumed during microbial degradation of biodegradable material to be assessed.

The confirmed nominal capacity is 300 mL. The exact bottle material, glass grade, stopper configuration, calibrated volume tolerance, dimensions and numbering arrangement are [confirm]. These specifications should be verified before making claims about borosilicate construction, calibrated capacity or specific analytical-method conformity.

How to Use the BOD Bottle 300ml

1. Clean the bottle and inspect it for cracks, chips or contamination.
2. Prepare the water or wastewater sample according to the applicable BOD test method.
3. Fill the bottle using the procedure specified by the analytical method while minimizing unintended air entrapment.
4. Determine the initial dissolved oxygen concentration as required.
5. Stopper the bottle correctly and incubate the sample under the conditions specified by the chosen BOD method.
6. Measure dissolved oxygen again after the prescribed incubation period.
7. Calculate biochemical oxygen demand using the applicable analytical procedure and dilution factors.

Safety note: Handle wastewater samples as potentially contaminated material. Wear appropriate laboratory PPE, disinfect reusable equipment where required and follow the validated analytical method rather than relying on general instructions alone.

Care & Maintenance

• Clean and decontaminate the bottle after each test using the laboratory’s approved procedure.
• Keep the bottle and stopper free from residues that could affect subsequent samples.
• Inspect sealing surfaces and the bottle body for damage before analytical use.
• Store clean bottles protected from dust, impact and cross-contamination.

Frequently Asked Questions

What is a BOD Bottle 300ml used for?

A BOD Bottle 300ml is primarily used for biochemical oxygen demand testing of water and wastewater. Dissolved oxygen is measured before and after controlled incubation to determine oxygen depletion.

Why are 300 mL bottles commonly used for BOD testing?

A 300 mL bottle is a commonly specified vessel size in established five-day BOD laboratory procedures and is widely associated with BOD5 testing.

What material is the STEMAids BOD Bottle made from?

The exact material is [confirm]. Borosilicate glass or another specific glass composition should not be claimed until verified by STEMAids.

Does the BOD bottle come with a stopper?

The exact supplied stopper configuration is [confirm]. BOD testing requires appropriate closure of the sample bottle to control unwanted interaction with atmospheric oxygen.

Can this bottle be used for wastewater testing?

Yes. BOD testing is routinely applied to water and wastewater samples, including municipal and industrial wastewater, using an appropriate validated analytical method.
