A volumetric flask with a polypropylene (PP) stopper is a type of laboratory glassware used for accurately measuring and dispensing precise volumes of liquids. The volumetric flask is a cylindrical-shaped container with a narrow neck and a graduation scale for measuring the volume of liquid. The polypropylene stopper is a type of plastic cap that fits snugly onto the neck of the flask, providing a secure and airtight seal.
The glass volumetric flask with a PP stopper is used in laboratory experiments and analyses that require precise liquid measurements. The flask is designed to hold a specific volume of liquid and is calibrated to deliver an exact volume when filled to a certain mark. The PP stopper provides a secure seal, preventing evaporation and contamination, and making it ideal for storing and transporting liquids.
The glass volumetric flask with a PP stopper is typically made of high-quality, chemically-resistant glass, ensuring its durability and longevity, even when used in harsh laboratory environments. The polypropylene stopper provides a tight seal, making it ideal for use in a wide range of applications, from chemical and biological experiments to clinical and industrial analysis.
