Wheaton 227580 BOD Bottle, 2 Liter, Robotic Stopper, Unnumbered, 128mm Diameter x 271mm Height

This Wheaton Boston round BOD bottle has a borosilicate glass body, a robotic glass stopper, and an unnumbered marking area. BOD (biochemical oxygen demand) bottle is used to hold a water sample for testing and analyzing dissolved oxygen, organic material, and aerobic biological organisms. The bottle's borosilicate glass body provides chemical, thermal expansion, shock, and heat resistance. Its Boston round shape is used for applications that require a rounded body, short neck, and narrow mouth to store liquid samples and solutions, and dry materials. The rounded shoulder forces air out of the bottle as it is filled, and the flared mouth forms a water seal around the stopper to help prevent air from being drawn into the bottle during incubation. The robotic glass stopper helps secure contents and allows robotic removal and replacement, and the stopper has a tapered bottom that helps prevent air entrapment. This bottle has an unnumbered marking area to label for security and accountability. This bottle is suitable for use in biochemical oxygen demand procedures and analysis including incubating diluted samples of sewage, sewage effluents, polluted waters, and industrial wastes.Lab bottles are used to store, hold, and mix liquids, powders, and other substances in a wide variety of scientific industries. Lab bottles have a more pronounced neck and shoulder than jars. Lab bottles are manufactured with a combination of characteristics in order to meet the demands of particular applications, such as for solution dispensing, mixing, and weighing, and use in centrifuge operations. They come in many shapes for specific applications, with a variety of mouth or nozzle shapes and sizes for specific use. Lab bottles are made from materials, such as glass (borosilicate or soda-lime) and an array of plastics, which are selected for chemical and thermal expansion resistance, transparency, and their adaptability in a variety of applications. Lab bottle interiors, caps, and lids are often lined with a protective material. Caps and lids help seal bottles to prevent solutions from spilling. The capacity refers to the fluid amount held by a lab bottle, and is commonly measured in milliliters (mL) and liters (l), and sometimes in ounces (oz). Lab bottles are suitable for use in chemistry and biology applications, as well as in pharmaceutical and scientific testing.
