300mL Black B.O.D. Bottle, Glass Robotic Stopper, Wheaton | DWK Life Sciences

This is a standard 300mL B.O.D. bottle with a heavy coating of black PVC plastic that blocks all visible light up to 800nm. This inhibits the production of oxygen by algae. This bottle is recommended for use in marine photosynthesis projects where a comparison of oxygen in a light and dark bottle is required. This bottle is supplied complete with a glass robotic stopper and an opaque black cap.
