Wheaton 300mL Black BOD Bottles with Robotic Stopper for Light Sensitive Samples

Wheaton Science Black 300mL B.O.D. Bottles with Plastisol Safety-Coating. These 300mL B.O.D. bottles are similar to the 60mL B.O.D. bottles but are offered with bar coding and coated with black PVC for use in light bottle/dark bottle testing. Coating blocks all visible light up to 800nm. This inhibits the production of oxygen by algae. Interchangeable ground stoppers are tapered to prevent air entrapment. Bottles have a flared lip for water seal. A white marking area on the bottles makes it easy to identify samples. Diameter x Height: 73 x 167mm. 20/Case
