BOD Bottles, Black-WTN 227667

These 300 mL BOD bottles are similar to the 60 mL BOD bottles but are offered with bar coding and coated with black PVC for use in light bottle/dark bottle testing. 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. Sold in case quantities only.
