This Nalgene narrow-mouth centrifuge bottle has a polycarbonate body and polypropylene screw closure. This centrifuge bottle has a narrow mouth for substance control and containment, and is used with centrifuge equipment and for applications that require a durable container. The polycarbonate body resists oils, greases, detergents, most inorganic acids, and impact over a wide temperature range. It is transparent to allow visual monitoring of fluids. Its Atlantic City (AC) round shape is used for applications that require a rounded body for dry and viscous samples, and it has a narrow mouth for greater substance control and containment. This lab bottle has a polypropylene screw cap lid to secure contents and help prevent spills and evaporation. It is autoclavable for applications that require sterilization.

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.
