The United Scientific 81203 Separatory Funnel Stopcock is an essential laboratory tool designed for precise and efficient separation of liquids. This 500ml separatory funnel, manufactured by United Scientific, is made of high-quality borosilicate glass, ensuring durability and resistance to thermal shock.
The separatory funnel features a stopcock, a critical component that allows for the controlled release of liquid. The stopcock is made of PTFE (polytetrafluoroethylene) material, which is known for its exceptional chemical resistance and exceptional low friction, ensuring a smooth operation. It also has a built-in bubble trap, which helps to prevent air from entering the funnel during the separation process, maintaining the accuracy of the experiment.
The stopcock is attached to the funnel with a PTFE stopper, which is easy to tighten and loosen, providing a secure seal. The stopper is also equipped with a rubber washer for an extra layer of protection against leakage. The funnel itself has graduated markings on the side, allowing for easy and precise measurement of liquids.
The United Scientific 81203 Separatory Funnel Stopcock is designed for practical use. It has a wide neck, making it easy to pour and transfer liquids without spillage. The funnel is also equipped with a tapered bottom, which helps to ensure that the layers of liquids separate effectively.
In summary, the United Scientific 81203 Separatory Funnel Stopcock is a reliable and durable laboratory tool. Its high-quality materials, PTFE stopcock, and built-in bubble trap make it an excellent choice for accurate separation of liquids in a variety of laboratory applications.
