This Wheaton cylindrical reagent bottle has an amber borosilicate glass body, a ground glass stopper, and a pour lip. This reagent bottle has a narrow mouth for substance control and containment, and it is used to hold fluids that can have a solvent or chemical reaction. The amber borosilicate glass body provides chemical, thermal expansion, shock, and heat resistance, and provides UV ray protection for light-sensitive samples. Its cylindrical shape is used for a wide variety of applications that require solution containment. The octagonal ground glass stopper seals the bottle to secure contents and help prevent spills and evaporation. This bottle has a pour lip at the top of the neck opening to help prevent drips. It is autoclavable for applications requiring sterilization. This bottle is suitable for use mixing and storing light-sensitive samples, liquids, and reagents.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.Wheaton Industries Inc. manufactures and repackages laboratory ware, instrumentation, containers, and associated products under the brands Wheaton Science Products and Wheaton Science Packaging.
