This Wheaton cylindrical diagnostic bottle has a PET body and a polypropylene screw cap with an F217 foam liner, and it is sterilized. This diagnostic bottle is used to hold small-volume buffer and reagent samples and for storage and shipment of applications. The PET (polyethylene terephthalate) body provides rigidity, and is lightweight and impact, liquid, and gas resistant. Its cylindrical shape is used for a wide variety of applications that require solution containment. This lab bottle has a polypropylene screw cap with an F217 foam liner to secure contents and help prevent spills and evaporation. The F217 cap liner has a LDPE (low-density polyethylene) foam core between two layers of LDPE. This lab bottle is sterilized by gamma irradiation for applications that require sterilization. This bottle is suitable for mixing, storing, and sampling of alcohols, solvents, reagents, and buffers, and for use with test kits and small-volume 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 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.
