Ideal for incubating diluted samples of sewage, sewage effluents, polluted waters, and industrial wastes.

These 60 ml borosilicate glass bottles feature a shoulder radius that sweeps all air from inside the bottle during filling.

The bottles are designed with a permanently screened-on label and are available with either glass robotic stoppers or glass pennyhead stoppers. Bottles may be used with B.O.D. bottle rack. Bottle rack is rugged with plastic coating for corrosion resistance and quietness and holds twenty 60 ml B.O.D. bottles.

The interchangeable stoppers have a tapered bottom that also prevents air entrapment. Bottles have a flared mouth to form a water seal around the stopper that prevents air from being drawn inside during incubation.
