This Wheaton Boston round media bottle has a borosilicate glass body, a polypropylene screw cap with a pour ring, and an exterior safety coating. This media bottle is used to hold samples 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 and solutions, and dry materials. This lab bottle's white polypropylene screw cap helps to secure contents and prevent spills and evaporation, and its polypropylene pour ring neck insert helps reduce drips when dispensing contents.

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).
