Qorpak Clear Glass Graduated Medium Round Bottle with Black Phenolic Polyseal Cone Lined Cap

The Qorpak wide-mouth medium round lab bottle has a clear flint glass body, a black thermoset cap with a cone-shaped LDPE polyseal liner, and milliliter graduations. 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 medium round shape, also known as Atlantic City (AC) round, is used for applications that require a rounded body and wide mouth for dry and viscous samples. The black thermoset phenolic seal-lined cap secures contents to help prevent spills and evaporation. The cap's liner is made of low-density polyethylene (LDPE) molded in a cone shape to form to the inside of the bottle's neck, providing a tight seal and a chemical barrier. The bottle is graduated in milliliter (mL) markings for volume measurements and for dispensing and storing. This bottle is suitable for use in mixing and storing samples or liquids, among other 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.
