BOD Bottles for incubating diluted samples of clean water, waste water, effluent water and polluted water duting the 5 day biochemical oxygen demand (BOD) test. These bottles feature flared mouth to form a water seal to prevent the ingress of air during incubation. The interchangeable stoppers have a tapered bottom that also prevent air entrapment.
The stopper joint on BOD bottles is compatible with the probes of leading BOD and Do meters. Bottle have large, permanent marking squares. BOD Bottles are manufactured from high-quality Borosilicate tubing, this glass makes them much less susceptible to etching when compared to traditional BOD bottles.
