This Wheaton Boston round lab bottle has a soda-lime glass body, a screw neck opening that accommodates standard-sized caps, and an exterior safety coating. This lab bottle has a narrow mouth for substance control and containment. The soda-lime glass body resists heat, thermal expansion, and shock, and it 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 screw neck opening accommodates standard-sized threaded caps (sold separately). This lab bottle has a non-slip exterior safety coating that resists shattering and helps to retain contents for disposal in case of breakage, and it helps prevent slipping for ease of handling. The plastisol safety coating is a solution of PVC (polyvinyl chloride) resin in a liquid plasticizer that covers the glass bottle and cools to form a plastic coating. This lab bottle is autoclavable for applications that require sterilization. This bottle is available as a jug in the 80-ounce size with a finger handle for pouring and handling control. The soda-lime glass conforms to United States Pharmacopoeia (USP) Type III requirements for solvent, chemical, and sample storage, such as some dry powder types, and in heat-dry sterilization applications. This bottle is suitable for use in mixing and storing samples, liquids, and volatile substances.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.
