This Corning Pyrex cylindrical gas washing bottle has a borosilicate glass body, a taper stopper with an integrated plain-tip vertical tube, and a hexagonal base. This washing bottle is used to wash or dry gases and to hold a washing or drying medium. The borosilicate glass body provides chemical, thermal expansion, shock, and heat resistance. Its cylindrical shape is used for a wide variety of applications that require solution containment. A taper stopper helps secure contents and has an integrated plain-tip vertical tube to disperse gas into the contained medium. The stopper's inlet and outlet tubes accept 8mm flexible tubing (sold separately) for directing gas flow through the washing or drying medium. It has a hexagonal base for stability The lab bottle meets borosilicate glass code 7740 for quality assurance. This bottle is suitable for washing, drying, or humidifying gases, saturating a liquid with a gas, or saturating carbon dioxide and air mixtures with water for gassed cell culture incubators.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.Corning manufactures consumable glass, ceramics, and plastic laboratory tools for life science research, industrial, and educational applications. The company, founded in 1908, is headquartered in New York, NY, and makes ISO-certified products.
