BOD Bottles with Penny Head Stopper

BOD Bottles with Penny Head Stopper are precision laboratory glass containers specifically designed for conducting Biochemical Oxygen Demand (BOD) testing. This test measures the amount of dissolved oxygen required by aerobic biological organisms to break down organic material in water. These bottles are a critical standard in water and wastewater analysis. The penny head stopper is a flat, disk-shaped ground-glass stopper designed to rest snugly in the bottle’s narrow neck. This ensures a gas-tight seal while minimizing headspace and air exchange during incubation. The flat “penny” design helps prevent pressure buildup and enables easy insertion and removal without disrupting the test. These BOD bottles are manufactured from borosilicate glass, known for its thermal stability, high clarity, and chemical resistance, making them suitable for repeated autoclaving and consistent test performance.
