The Qorpak narrow-mouth Boston round bottle has a flint glass body and a black thermoset phenolic cap with a vinyl-coated pulp-board liner. This lab bottle has a narrow mouth for substance control and containment. The clear flint glass body provides visual clarity, solidity, solution compatibility, and versatility for use in an array of common applications, and it is heat, gas, and vapor resistant. 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 vinyl-coated pulp-board liner provides moisture and chemical resistance. It is made of high-density polyethylene (HDPE) coated paper, which is coated with vinyl and then laminated to the pulp board. This bottle is suitable for general use mixing and storing food, beverages, liquids, pharmaceuticals, and chemicals including mild acids, alkalis, solvents, alcohols, and oils.

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.
