RS PRO PP Funnel, With 75mm Funnel Diameter, 10mm Stem Diameter Model No 2012424

RS PRO PP Funnel, With 75mm Funnel Diameter, 10mm Stem Diameter Model No 2012424 is a common laboratory tool used for transferring liquids or fine-grained substances from one container to another. It consists of a conical or cylindrical-shaped tube with a wide opening at the top and a narrow stem at the bottom. The funnel's design allows for controlled and precise pouring of liquids or substances, minimizing the risk of spillage and contamination.

Labware funnels come in various sizes, materials, and designs, each tailored to specific laboratory applications. The choice of funnel depends on factors such as the volume of liquid to be transferred, the type of substance being handled, and the desired level of accuracy.

One of the primary functions of a lab funnel is to aid in filtration. When equipped with a filter paper or a fine mesh, it allows the separation of solid particles from liquids. This is commonly used in various laboratory procedures, such as gravimetric analysis, where precise separation and measurement of solid samples are essential.

In addition to filtration, funnels are instrumental in the transfer of liquids between containers with minimal spillage. The wide opening at the top of the funnel makes it easy to pour liquids into the funnel without the risk of splashing or wastage. The narrow stem at the bottom ensures a controlled and steady flow of liquid into the target container.

Moreover, funnels are utilized in a range of laboratory processes, including decantation, extraction, and chemical reactions. For example, during extraction processes, a separatory funnel with a stopcock allows the separation of immiscible liquids by controlling the flow of one liquid over the other.

Labware funnels are typically made from materials such as glass, plastic, or stainless steel. Glass funnels are preferred for applications requiring chemical resistance and transparency to monitor the flow and level of liquid accurately. Plastic funnels, on the other hand, are lighter, durable, and more cost-effective, making them suitable for routine laboratory tasks.

In summary, a labware funnel is a versatile and indispensable tool in the laboratory setting. It facilitates the safe and precise transfer of liquids and substances between containers, aids in filtration processes, and is a fundamental component in various laboratory procedures, contributing to the overall efficiency and accuracy of scientific experiments and analyses.
