• Narrow-mouth lab bottle for substance control and containment.
• Soda-lime glass body for heat, shock, and thermal expansion resistance, and its ability to be used for packaging some dry powders.
• Boston round shape for applications that require a rounded body, short neck, and narrow mouth to store liquid samples and solutions, and dry materials.
• Black thermoset phenolic seal-lined cap secures contents to help prevent spills and evaporation.
• Cone-shaped LDPE polyseal cap liner provides a tight seal and a barrier.

This Wheaton Boston round lab bottle has a soda-lime glass body, a black thermoset phenolic cap, and a cone-shaped LDPE polyseal cap liner. This lab bottle has a narrow mouth for substance control and containment. The soda-lime glass body resists heat, thermal expansion, and shock, and can be used for packaging some dry powders.. 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 black thermoset phenolic seal-lined cap secures contents to help prevent spills and evaporation. The cap's liner is made of LDPE (low-density polyethylene) molded in a cone shape that forms to the inside of the bottle's neck, providing a tight seal and a barrier. This bottle comes with an adhesive hazardous communication label for content identification and safety information, which can be applied over the top of a closed lid to create a tamper-evident seal. The soda-lime glass conforms to United States copoeia (USP) Type III requirements for solvent, , and sample storage, such as some dry powder types, and use in dry-heat sterilization applications. This bottle is suitable for use in mixing and storing samples or liquids, among other applications. 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 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 a 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 ceutical and scientific testing.
