The Qorpak wide-mouth round bottle has a clear glass body, a black polypropylene cap with a PTFE disc liner, and it is autoclavable. This lab bottle has a wide mouth for filling ease, and is used for liquid and sample storage. The clear flint glass body provides visual clarity, solidity, solution compatibility, versatility, and heat, gas, and vapor resistance. Its round shape is used for a wide variety of common applications that require fluid containment. The black polypropylene screw cap with a liner secures contents to help prevent spills and evaporation. The cap's 0.015-inch disc liner is made of chemically-inert polytetrafluoroethylene (PTFE) to reduce interference with lab tests. PTFE resists many chemicals, moisture, and temperatures ranging from -400 to 500 degrees F. This lab bottle is ready to autoclave for applications that require sterilization. This bottle is suitable for use in general purpose mixing, storing, and sampling 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.

Qorpak manufactures and supplies glass jars, jugs, beakers, and bottles, and fiberboard mailing tubes and mailers for fluid containment and shipping applications in the pharmaceutical, chemical, petroleum, environmental, and educational fields. The company is headquartered in Bridgeville, PA.
