Wheaton 219817 Clear Glass Graduated Media Bottle, 250mL, With 33-430 Solid Black Phenolic PTFE-Faced Rubber Lined Cap (Case of 48)

This Wheaton Boston round media bottle has a borosilicate glass body and a black thermoset phenolic cap with a PTFE-faced rubber liner, and it is graduated. This media bottle is used to hold samples and for storage, mixing, and sampling applications. The 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, solvents, and chemicals, and dry materials. This lab bottle has a black thermoset phenolic seal-lined screw cap to secure contents and help prevent spills and evaporation. The white rubber cap liner provides resilience, moisture resistance, and low gas transmission. An additional PTFE (polytetrafluoroethylene) facing resists many chemicals, moisture, and temperatures ranging from -400 to 500 degrees F. This lab bottle has a marking area to label for security and accountability and graduations for measured dispensing and storing. A pour lip at the top of the neck opening helps prevent drips. It is autoclavable for applications that require sterilization. This bottle comes with an adhesive hazardous communication label for content identification and safety information that can be applied over the top of a closed lid to create a tamper-evident seal. The borosilicate glass conforms to United States Pharmacopoeia (USP) Type I requirements for glass containers. This bottle is suitable for use in mixing and storing analytical lab samples, food, high purity chemicals, acids and solvents, environmental samples, pharmaceuticals, and diagnostic 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. The company, founded in 1888 and headquartered in Millville, NJ, meets International Organization for Standardization (ISO) 9001/2008 and 14001/2004 standards.
